Rapid diagnostic testing for malaria has revealed that most febrile patients in Africa and Asia do not have malaria. FIEBRE will find out what they have and how to treat them.
Funded by the UK Foreign, Commonwealth and Development Office, FIEBRE collaborators include LSHTM, Liverpool School of Tropical Medicine, Universities of Barcelona, Oxford and Otago, and partners in Laos, Malawi, Mozambique and Zimbabwe.
Study protocols, standard operating procedures, data collection tools and related materials will be made available as they are finalised and approved.
The objective of FIEBRE is to provide evidence:
- on the most common infectious causes of fever;
- on antibiotic susceptibility of bacterial causes;
- on how local perceptions of fever affect treatment practices including the use of diagnostics and antimicrobial drugs;
- to inform clinical guidelines and algorithms on how to manage non-malarial fevers.
The FIEBRE study will help to fill the gaps in evidence by means of a multi-centre study in countries with a high burden of infectious disease from which few or no data are available. The clinical and laboratory components of the study will focus on detecting infections that are treatable and/or preventable. Ethnographic work with community members, prescribers and public health workers will seek to understand how fever is understood by different communities of practice, and how this affects treatment practices.
The results will help to inform updated, evidence-based algorithms for the management of febrile illness, and provide data that may be used to design new diagnostics and rational approaches to disease surveillance. These outputs will ultimately help health systems and providers to provide more appropriate care to patients and lead to better clinical outcomes.

We currently know little about the antibiotics being used to treat febrile illnesses and how we could safely reduce antimicrobial use. Social science research has been called for to understand our relationships with antibiotics and how we can optimise their use in fever case management. The social science component of FIEBRE seeks to understand how fever is understood by different communities of practice and how this affects treatment practices. It aims to explore how fever case management and antimicrobial use are entwined with social, economic and political life in Malawi, Myanmar and Zimbabwe.
The work includes participant observation and interviews in a variety of settings including clinics, hospitals, pharmacies, markets and households, as well as a medicines survey to identify broader patterns of antibiotic use and access at the community level. Findings will be used alongside clinical data to inform revised guidelines for fever case management that are sensitive to the contexts in which they are used. See the protocol (pdf) for more details.
What are we looking for?
Some diagnostic tests are performed at or near the point of care at each study site. Further pathogen-based diagnostic tests and quality control tests will be performed at internationally recognised reference laboratories. For more details see the FIEBRE protocol paper.

The Mahidol Oxford Tropical Medicine Research Unit (MORU) develops effective and practical means of diagnosing and treating malaria and other neglected diseases such as melioidosis, typhus, TB and leptospirosis. MORU was established in 1979 as a research collaboration between Mahidol University (Thailand), Oxford University (UK) and the Wellcome Trust UK. It is a network of a diversity of subunits including the Lao-Oxford-Mahosot Hospital-Wellcome Trust Research Unit, Lao PDR (LOMWRU). This is a small clinical tropical medicine research group based at Mahosot Hospital, Vientiane. LOMWRU builds diagnostic, clinical and research capacity to help improve global, regional and Lao public health. LOMWRU’s main areas of research interest are in the diagnosis, epidemiology and treatment of malaria, rickettsial infections, leptospirosis, melioidosis, community-acquired septicaemia, central nervous system infections, the causes of acute fevers and public health aspects of medicine quality problems.
The main study site is Vientiane provincial hospital, a 100-bed hospital approximately 70 km from Mahosot Hospital. The team consists three study doctors and two laboratory technicians. The principal investigator is Assoc Prof Mayfong Mayxay with Dr Elizabeth Ashley and Prof Paul Newton as co-investigators.
The Malawi site is in Chikwawa district in the southern region of Malawi. Chikwawa district is 5,000 km2 with a population of 350,000 and is served by Chikwawa District Hospital. The study is taking place in Chikwawa District Hospital and a second site at St Montfort Hospital, Ngabu 30 km away has been opened up to help increase inpatient recruitment.
The work is based out of the Malawi-Liverpool Wellcome Trust Clinical Research Programme (MLW) . Established in 1995, MLW is an internationally-recognised health research institution led by Malawian and international scientists with the aim of improving the health of people in sub-Saharan Africa. MLW is built around laboratories, located at Queen Elizabeth Central Hospital, in Blantyre.
CISM was established in 1996 with the objective of conducting biomedical research in those diseases that affect the most poor and vulnerable. The Centre includes a fully equipped laboratory including parasitology, haematology, biochemistry, microbiology, (including biosafety level III premises), molecular biology (including PCR and RT-PCR) and immunology. CISM has been running a Demographic Surveillance System (DSS) since 1996, covering the whole district’s population and it set up a morbidity surveillance system at Manhiça District Hospital (MDH) in 1998. Overall, data on over 70,000 paediatric admissions and more than 1.2 million outpatient visits have been collected in the past 18 years. CISM’s other activities include: malaria screening, microbiological surveillance; pneumonia surveillance and conducting studies on issues with an important impact on public health policies in the country.
The study is being conducted in the district of Manhiça (population 182,000 inhabitants, 2300 km2), a rural area located 90 km away from the capital Maputo. MDH acts as the referral health facility for the area. The study is also working at the Hospital Geral José Macamo in Maputo.
The study’s Principal Investigator at the site is Professor Quique Bassat, supported by co-investigators Dr Marta Valente and Dr Pio Vitorino, in addition to a larger team of Mozambican-based staff: Dr Nelson Tembe; Dr Sozinho Acácio; Dr Ajanovic Andelic, Campos Mucasse (Project manager); Vânia Afuale (Project assistant); Humberto Mucasse (Field coordinator); Teodimiro Matsena (Data manager); Anelsio Cossa (Laboratory coordinator); Manuel Muamede (Adult nurse coordinator); and Ilídio Cherinda (Paediatric nurse coordinator).
The researchers in Zimbabwe are based at the Biomedical Research and Training Institute (BRTI) in Harare. Established in 1995, the BRTI provides effective and professional research facilities including laboratory facilities for molecular diagnostics, micro-biology, serology, TB and immunology. BRTI aims to improve health and quality of life in Africa through conducting research and training. Its role is to provide the infrastructural support that researchers in all aspects of health need to become effective in influencing policy.
The study site incorporates major hospitals in Harare (urban setting) Harare Central Hospital (HCH) and Chitungwiza Hospital. These hospitals have both inpatient and outpatients care of all age groups with patients referred from local clinics and provincial hospitals. The hospitals serve urban and peri-urban communities in southern Harare. In addition, outpatients are being recruited from Glen View and Rutsanana polyclinics in south-western Harare.
The BRTI team is led by Dr Katharina Kranzer (Principal investigator) with Professor Rashida Ferrand (Co-principal investigator) and comprises: Dr Ioana Olaru (Study coordinator), Ethel Dauya (Field manager), Tsitsi Bandason (Data manager), Salome Manyau (Social science lead), Beauty Makamure (Laboratory manager) and Tendai Muchena (Administrator). Partners include the Department of Medicine and Paediatrics at Harare Hospital and Chitungwiza Hospital, the University of Zimbabwe and Harare City Health Services.
Even though rapid diagnostic testing (RDT) for malaria has revealed that most febrile patients in Africa and Asia do not have malaria, FIEBRE still needs to confirm this by testing all participants at the point of care. In order to standardise diagnostic testing further external quality confirmatory (EQC) assessment of site results are performed at the Clinical Diagnostic Parasitology Laboratory (CDPL) at Liverpool School of Tropical Medicine.
Many stages are involved in testing for malaria starting from the point when a patient is enrolled on site to the final results being logged on the database at LSHTM:
- mRDT performed at patient enrolment
- Positive results reported to clinical team
- Thick and thin blood smear prepared on microscopic slides
- Slides double-read for malaria only (presence or absence, density and species) by in-country microscopists who have achieved expert status in the WHO (or similar) qualification scheme.
- In-country microscopists read the smears for all mRDT-positive and 10% of mRDT-negative study participants. FIEBRE uses a combination mRDT that detects two different parasite antigens: histidine-rich protein 2 (HRP2) which is produced only by Plasmodium falciparum parasites; and pan-specific Plasmodium lactate dehydrogenase (pLDH) which is produced by all malaria parasite species.
- Site coordinators select 10% of all slides collected at their site for EQC at the CDPL, to be read for malaria and also for Borrelia spp and other pathogens
- Slides are received in by the LSHTM team who distribute to the reference laboratories
- CDPL receive stained thick and thin blood smears where they are checked and catalogued
- Each slide is read by two Health and Care Professions Council (HCPC) registered biomedical scientists with experience in reading blood smears. They are examined for the presence or absence of malaria, borrelia and any other relevant blood parasites. The smears are read blind without the knowledge of the results from the originating site.
- Results are recorded for each slide and once complete the data is submitted to the FIEBRE co-ordinator at LSHTM.
Site activities essentially finished during 2021 as recruitment ended and sample shipments were despatched. The main work now revolves around team collaboration on data queries and analysis of findings.
The final participant samples (sera, blood, plasma, blood cell pellet, buffy coat, PAXgene tubes, swabs) arrived at LSHTM from Laos and Mozambique in November 2021. Microbiology and mycobacteriology isolates were shipped directly to international reference laboratories in Germany and New Zealand.
FIEBRE enrolled child and adult inpatients and outpatients who presented with fever over ≥24 months. A venous blood sample and pharyngeal swabs were collected from all participants; a urine sample was collected from selected participants. In addition, blood and pharyngeal samples were taken from community controls matched to outpatients by age, gender, residence and month of recruitment. The controls were also surveyed to obtain representative data about treatment seeking and medicine use.

The MLW team held two successful local dissemination meetings in a COVID-19-safe format for St Montfort Hospital and Chikwawa District Hospital in mid-May 2021. The meetings were attended by representatives from the hospital management teams, lead clinical officers, district health officers, the matrons, and other members of staff from all sections of the hospitals including clinicians, nurses, anaesthetists and administrators.
The meetings covered presentations on:
- Study operations review
- Community field work
- Scientific and statistical data
- Social science key findings
The meetings were very well received and emphasised some basic practice points. Further meetings at a national level will be organised when the reference laboratory results are available later in the year.
The social science team discussed their research from clinical observations and the focus on cotrimoxazole being the most frequently used drug at the facilities and within the community.
The key take home messages were:
• A limited number of antibiotics are recognised and there are very low stocks of antibiotics in public health clinics – not suggesting that antibiotics are overused everywhere
• Health workers are very committed and manage in challenging conditions where essential medicines beyond those provided by the international donor programme are very limited
• Opportunities exist for rapid gains through antimicrobial resistance policy that reflects the context of this limited access and centres on foregrounding care not restricting access to antibiotics.
FIEBRE finished recruiting patients in Malawi on 31 March 2021. Follow up activities will continue during April.
Congratulations to everyone involved in contributing to the study in both Blanytre and Chikwawa. Many thanks to the clinical, laboratory and technical staff, community engagement team, administrators, data scientists, patients and the local community.
The first patient was enrolled on 4 July 2018 at Chikwawa District Hospital (CDH). In total, 1765 patients were recruited (over 6200 screened) and the team reached the outpatient recruitment target of 600 for both adults and children. Control recruitment was very effective at 98% and 28-day follow up was high at 91%. This reflects the dedication of the community engagement team.
Initially, FIEBRE started at CDH and second site opened at St Montfort Mission hospital in May 2019 in order to help increase inpatient recruitment.
Community engagement was integral to the study. FIEBRE was helped by long-established community sensitisation work to research in the area. There's been particular interest and concern about the amount of blood taken. These issues are addressed by the team through their continued commitment to working with the local community.
The team faced many challenges such as flooding, Cyclone Idai in March 2020, the COVID-19 pandemic and a high number of eligible patients declining to participate for a variety of reasons including:
- Concern about donating blood/large volume when anaemic (severe anaemia is commonplace in Chikwawa)
- Traditional beliefs about losing and sharing blood
- Wanting to seek consent from husband or elder
These sensitive issues were addressed over the course of the study by many staff and patient education and sensitisation sessions explaining the safety and desirability of blood testing in patients who might be suffering from infections. On the whole, these efforts were bearing fruit with increased inpatient recruitment until the arrival of COVID-19 in the spring of 2020.
The COVID-19 pandemic had a considerable impact on the study’s activities; national and institutional restrictions were imposed which slowed down enrolment and limited activities. Although personal protective equipment was available for staff, and infection control measures were in place, with masks and screening at the hospital entrance, people were reluctant to seek healthcare due to a fear of COVID-19 transmission in health centres and of being diagnosed and being sent to a COVID-19 treatment centre.
Despite all the challenges, the FIEBRE team have been able to help support and add to the overall level of care and treatment in the area by providing clinical microbiology services in CDH and SMH for the first time and diagnosing HIV and TB in patients who might otherwise have slipped through the net. FIEBRE staff followed up any positive blood cultures immediately and advised clinicians on antibiotic choice and length of treatment. The study hopes to leave a legacy whereby this service will be continued by the MLW core team.
Many of the FIEBRE team members in Malawi were undertaking their first research role. It has been rewarding to see the team develop and no surprise to see team members grow into more senior roles or be taken up by other studies, research support units or research institutions in Malawi.

FIEBRE finished recruiting patients in Mozambique on 26 February 2021. Control and follow up activities will continue throughout March.
CISM began enrolling adult patients at Manhiça Health Research Centre on 13 March 2019 after paediatric recruitment started in November 2018. A second site, Hospital Geral José Macamo in Maputo, was opened on 28 November 2019. This helped boost inpatient numbers significantly and improved the patients’ care with access to blood culture results.
In total, 2136 patients were enrolled during this period; the highest number of participants of all the sites. This is a great achievement. The team reached the outpatient child recruitment target of 600. The site is the only one which has recruited participants who tested positive for SARS-CoV-2.
Congratulations to everyone involved in contributing to the study’s success - the clinical, laboratory and technical staff, administrators, data scientists, patients and local communities.
Initially, there were some clinical issues which included difficulty in taking blood and urine samples from children. Day 28 follow up has been quite problematic with a high rate of refusals and some loss to follow up due to migration (families moving for work), accessibility during the rainy season and local perception of loss of blood. Blood extraction in particular is a sensitive issue and can be associated with ill-health especially among children. Moreover, some healthy people were not interested in participating as controls.
The COVID-19 pandemic had a considerable impact on the study’s activities; inpatient recruitment was closed down in Maputo and community activities were stopped during the first wave. National and institutional restrictions were imposed which slowed down enrolment and limited field activities.
On a personal level, many of the clinical staff were infected with SARS-CoV-2 although none severely. This was a critical period during which infection protection measures and disinfection of working areas were reinforced. It was a stressful time for all the staff and their families. Despite these COVID-19 issues along with rising patient numbers and infections in the community, the team managed to continue working throughout.
In spite of the many challenges, the team’s hard work and dedication has contributed greatly to the clinical diagnostic capacity at these hospitals through access to rapid diagnostic tests and laboratory cultures. This has benefitted both clinicians and patients, enabling clinicians to use the information to make accurate diagnoses and therefore quickly help provide the right treatment.
Listen to Justina Bramugy and Campos Mucasse talking about their experience on FIEBRE.
The LOMWRU team returned to the study site at Vientiane Provincial Hospital on 19 January 2021 for the main dissemination meeting. The preliminary results of the study, some microbiology data and early reference laboratory results were presented to clinicians, nurses and laboratory technicians for feedback.
The 2-hour session was chaired by Dr Siho Sengsavang, Deputy Director of Vientiane Provincial Hospital and Prof Mayfong Mayxay, Vice President of the University of Health Sciences, LOMWRU Head of Field Research and local PI who facilitated a discussion after talks by Dr Manophab Luangraj and Dr Vilayouth Phimolsarnnousith.
Watch a video summarising the study's activities.
The BRTI team held a series of successful dissemination meetings following the completion of recruitment in Zimbabwe on 30 September 2020,
Preliminary clinical results were presented at the polyclinics during October and November for the nurses and staff involved in FIEBRE. These received interesting feedback and led to discussions about effective antimicrobials and antimicrobial resistance.
A research dissemination meeting for major stakeholders at a policy level took place in Harare (with online attendees) on 30 November. The meeting covered several projects as well as FIEBRE and ARGUS: B-GAP, FAST and BREATHE trial.
Representatives from the Ministry of Health and Childcare, Harare Central Hospital, Parirenyatwa Hospital, Medicines control authority of Zimbabwe, Zimbabwe College of Public Health Physicians, National Microbiology Reference Laboratory, MSF, UNAIDS and many other institutions participated in the meeting.

Recruitment of FIEBRE participants ended in Laos on 31 October 2020. The LOMWRU team started enrolling patients on 9 October 2018 at Vientiane Provincial Hospital. In total, 1961 participants were enrolled during this period. The team reached the adult recruitment target of 600 for both in- and outpatients.
Congratulations to everyone involved in contributing to the study’s success - the clinical and laboratory staff, hospital, participants and local communities.
The first set of samples were shipped to LSHTM in early 2020 and are now at international reference laboratories awaiting diagnostics. Analysis of these samples will produce the first results of the study aside from preliminary data from point-of-care tests carried out on site. The dried blood spots from Laos are also currently being used for the MOS-DEF biomarker project.
The team faced clinical and logistical challenges including difficulty in taking blood samples from children and travelling long distances to recruit controls (healthy people who were not always interested in taking part). The team continued working throughout the COVID-19 epidemic despite national restrictions which slowed down enrolment and limited field activities.
FIEBRE has helped with the clinical diagnostic capacity and treatment of infectious diseases in the local community, as blood culture and other tests were not available in the hospital previously. The information collected by the study may contribute to the development of treatment guidelines for fever and antibiotic stewardship in the future, especially in settings where there's limited laboratory diagnostics or little data available.
The American Society of Tropical Medicine and Hygiene 2020 Annual Meeting (ASTMH 2020) took place 15-19 November 2020 virtually.

Participant recruitment in Zimbabwe finished on 30 September 2020. Many congratulations to everyone involved in contributing to the success of the study - the collaborators, participants and local communities.
Zimbabwe was the first FIEBRE site to start operating in June 2018. In total, 1923 participants were enrolled during this period. FIEBRE recruited patients presenting with fever to three major hospitals and three polyclinics in Harare.
The team at Biomedical Training and Research Institute (BRTI) continued working through outbreaks of cholera and typhoid, political and economic difficulties, despite all these challenges the outpatient adult target (of 600) was reached and many patients received life-saving diagnostics and treatment that otherwise they may not have been able to access. Through the study, a large number of patients with typhoid fever were diagnosed and received effective treatment. In addition, patients with other life-threatening infections such as tuberculosis, malaria and cryptococcal meningitis could be diagnosed.

A series of papers by Infectious Diseases Data Observatory (IDDO) that set out to explore the global distribution of infections that cause non-malarial febrile illness (NMFI) has been published in BMC Medicine.
The series was a collaboration by scientists and researchers from institutions across the world (including FIEBRE Pis from LSHTM, LOMWRU and University of Otago) who conducted large-scale systematic reviews of published literature to map the cause of febrile illness, once malaria had been excluded. Historically, malaria was assumed to be the cause of fever, however, the advent of rapid diagnostic tests, combined with intensified malaria control activities over the last decade, has substantially reduced incidence rates and it is now clear that most acute fever cases are of non-malaria aetiology.
The results of these systematic reviews, covering Africa, Latin America, and Southern and South-Eastern Asia, have been incorporated into an open-access online database that supports an interactive map that can filter data by country, microorganism type, patient age, sample type, pathogen family, genus and species, study year, geographic region and sub-region.

Researchers from the Anthropology of Antimicrobial Resistance (AMIS) team at the LSHTM work in countries across Africa and Asia, including Ghana, Uganda, Malawi, Zimbabwe, China, Myanmar and Thailand, to understand how antibiotics are used in society. The FIEBRE social science team has contributed valuable insights into this work on antibiotics and the rise globally in antimicrobial resistance. See what their research has discovered about the differing roles of antibiotics in Malawi and Zimbabwe.

The study aims to identify infections that are treatable and/or preventable, to assess antimicrobial susceptibility of bacterial pathogens, to evaluate host response biomarkers that may help in predicting illness severity and distinguishing bacterial from other causes of fever, and to collect qualitative data on care-seeking and treatment behaviours in each study area.
The paper details the harmonised study design, clinical and laboratory assessments, and data analysis plan; gives information about the sites; and outlines the study’s strengths and limitations. Listen to Prof David Mabey introduce the paper:
It is with great sadness that we announce the sudden death last week of our dear friend and former colleague Dr Amit Bhasin, who was our FIEBRE programme manager from 2016-2019. Amit first joined the School in 2002 as manager of the Gates Malaria Programme, and moved to Cambridge University in 2019 to run the Cambridge-Africa Programme. He will be greatly missed by his many friends around the world. Read the full tribute to Amit here, find out how to send your condolences to his family, about a memorial scholarship and other memorial events to be arranged in the future.
Read about Ja Seng Bawk's experience in quarantine when she returned home to Myanmar in March. She works as a Research consultant for FIEBRE social science in Myanmar.
On 22 March 2020, I cut my trip to London for the FIEBRE Social Science Analysis meeting short due to the COVID-19 pandemic and ensuing lockdowns. When I arrived at Yangon International Airport, no one asked for a medical certificate (although this was stated as a requirement on the official website, resulting in me spending the last two days in London in a futile effort to acquire one). Instead, I had to fill out a Health Declaration card, which was handed out on the plane and I gave to the airport authorities on arrival. They gave me the choice of a public medical centre free of charge or a hotel at 7 MMK lakhs (around 500 USD) up front in cash for the 14 days of quarantine. I chose the hotel, which was assigned by the authorities at the airport.
During my time in quarantine at the hotel I was able to join the FIEBRE meeting online and work on transcription. I felt very safe as I was tested for fever and symptoms every morning by a team of about 2 doctors and 3 nurses wearing full personal protective equipment. Food was delivered to the hotel door. I also received approximately four phone calls a day from a department of the Ministry of Health and Sports asking me about my daily condition during quarantine. Because of the very limited availability of PCR testing at the time in the country, I wasn’t tested. After 14 days with no symptoms, I finally returned to my home, safe and sound.
Shortly after this, Yangon went into lockdown. I had to stop all fieldwork and since then, I have been focusing on transcription of interviews at home. As of today (29 May 2020), Myanmar authorities have reported 206 confirmed COVID-19 cases and six deaths since the first cases were reported on 23 March 2020.
The team at Centro de Investigação em Saúde de Manhiça (CISM) in Mozambique have been operational for a year. CISM began enrolling adult patients at Manhiça Health Research Centre on 13 March 2019 after paediatric recruitment started in 23 November 2018. They reached their 1000th patient in November 2019.
Recruitment started at a new site, Hospital Geral José Macamo, Maputo, on 28 November 2019. This has helped boost inpatient numbers considerably and improved the patients’ care with the performance of blood culture, urine culture and antibiotic susceptibility testing. Latest data from end of February shows 1406 patients enrolled of which 916 are outpatients and 490 inpatients. More children than adults have been enrolled.
The team has faced several recruitment challenges during the study. Over the years, inpatient numbers have dropped at Manhiça District Hospital and there has been overlap with other studies making inpatient recruitment particularly difficult.
Day 28 follow up has been challenging with a high rate of refusals and some loss to follow up due to migration, accessibility and local perception of loss of blood.
Throughout the study, the team has received positive feedback from both patients and the hospital. FIEBRE has contributed to the clinical diagnostic capacity at these hospitals through access to rapid diagnostic tests and laboratory cultures. This has helped both clinicians and patients, enabling clinicians to use the information to make an accurate diagnosis and therefore provide the right treatment.

Impact of the COVID-19 pandemic on health care workers and the health care system in Zimbabwe (ICAROZ)
ICAROZ aims to implement comprehensive occupational health services including SAR-CoV-2 testing integrated with screening for major causes of morbidity and mortality in frontline health care workers, with rapid feedback of results to reduce nosocomial spread and trace household contacts.
The occupational health service will be set up in the eight communities and three hospitals (where FIEBRE operating). This will include community health care workers, nurses, midwives, auxiliary nurses, student nurses, cleaners, clerks, security, doctors, radiographers and other staff. The service will include a respiratory symptom screen, temperature, blood pressure and HbA1c measurement as well as an abbreviated physical exam. Anybody with fever and/or respiratory symptoms will be asked to submit a sputum sample for tuberculosis testing (depending on the duration of symptoms) and a nasoparyngeal swab will be taken for SARS-CoV-2. HIV testing either provider-delivered or self-testing using oral mucosal kits will also be offered. Results will be fed back to clients within 24 hours and appropriate measures for self-isolation will be discussed. Contact tracing will be conducted as per the national guidelines.

Marker of Severity Diagnostics for Evaluating Fever (MOS-DEF)
The Marker of Severity Diagnostics for Evaluating Fever (MOS-DEF) project is a sub-study of FIEBRE funded by Global Good. The objective of MOS-DEF is to develop, evaluate and deploy multiplex assays to measure human blood-borne factors that are released during an immune response. These factors may be informative to indicate the potential causes of fever, and/or, the severity of fever.
Analysis of the assay data will take the form of statistical and computational approaches to identifying individual markers or combinations of markers that could assist in identifying the root cause of fever, the severity of disease in patients presenting with fever and 28 day outcomes of fever cases.
As a sub-study of FIEBRE, the source materials of MOS-DEF are blood plasma collected from inpatient and outpatient settings in the FIEBRE study countries. Analyses will be informed by pre-existing clinical and laboratory data collected during FIEBRE.
Tegwen Marlais is leading the MOS-DEF multiplex assay development at LSHTM.

Antimicrobial resistance of Gram-negative bacteria from urine specimens (ARGUS)
Antimicrobial resistance (AMR) is a global problem affecting all countries irrespective of income and geographical location, and has been highlighted by the World Health Organization as one of the three most important public health threats of the 21st century. The increase in AMR is driven among others by inappropriate antibiotic use, insufficient or lacking infection control systems and the dissemination of successful bacterial clones harbouring resistance genes. Infections due to drug-resistant organisms are associated with increased mortality and risk of onward transmission, particularly in low-income settings where alternative antibiotics are not readily available, and pose an immense burden on weak health systems.
The ARGUS study aims to investigate the prevalence of and underlying molecular mechanisms for AMR in Gram-negative bacilli causing urinary tract infections in Zimbabwe. Taking into account that inappropriate antibiotic use is a main driver of AMR, this study plans to investigate antibiotic consumption in adults presenting to primary care. This information may be used to interpret the results on prevalence of antibiotic resistance.
The results from this study will be used to inform policy and development of treatment recommendations. Whole genome sequencing results will provide a better understanding of the prevalent resistance genes in Zimbabwe, of the spread of successful clones, and potentially will contribute to developing strategies to tackle AMR.

Carriage of antimicrobial resistance genes in children enrolled in the FIEBRE study
Antibiotic resistance (or antimicrobial resistance - AMR) is a well-recognised threat to global health. Few studies have examined how frequently people in Africa carry bacteria with genes that confer resistance to different antibiotics. The limited data available suggest that the rate of carriage of bacteria with resistant genes is high, even when the antibiotics in question are not widely available locally. There are unanswered questions as to where these genes have come from: previous antibiotic use (either prescribed or over-the-counter); environmentally from the hospital or community, or from eating food where antibiotics have been used in production. We also do not know how often carrying bacteria with AMR genes leads to disease, and whether this leads to a worse outcome for African children.
This study aims to investigate how often children with fever attending inpatient and outpatient facilities in Zimbabwe carry AMR bacteria, whether this relates to the cause of their fever, and leads to worse outcome. The rates of AMR bacterial carriage will be compared before and after admission (for inpatients) and with community controls. In a small number of samples, AMR genes within bacteria will be analysed and compared, to see if the spread of particular genes in hospitals and communities can be mapped, and to explore where the genes may have come from. This study is planned to produce initial data for a wider study in collaboration with vets and geographers looking at the spread of AMR genes in Zimbabwe, and what can be done to prevent that spread.
