    No full text
    As part of the ring vaccination trial in Guinea, Front Line Workers were invited to participate in a sub-study to provide additional information on the immunogenicity and safety of rVSVΔG/ZEBOV-GP. Here we summarize the information on the safety follow-up

    Prevalence and risk factors of brucellosis among febrile patients attending a community hospital in south western Uganda

    No full text
    Human brucellosis, a chronic disease contracted through contact with animals and consuption of unpasteurized dairy products is underreported in limited-resource countries. This cross-sectional study aimed to determine the prevalence and risk factors of brucellosis among febrile patients attending a community hospital in South western Uganda. A questionnaire that captured socio-demographic, occupational and clinical data was administered. Blood samples were tested for Brucella antibodies using Rose Bengal Plate Test (RBPT) and blood culture with standard aerobic BACTEC bottle was done. Of 235 patients enrolled, prevalence of brucellosis (RBPT or culture confirmed) was 14.9% (95% CI 10.6-20.1) with a culture confrmation in 4.3% of the participants. The factors independently associated with brucellosis were consumption of raw milk (aOR 406.15, 95% CI 47.67-3461.69); history of brucellosis in the family (aOR 9.19, 95% CI 1.98-42.54); and selling hides and skins (aOR 162.56, 95% CI 2.86-9256.31). Hepatomegaly (p < 0.001), splenomegaly (p = 0.018) and low body mass index (p = 0.032) were more common in patients with brucellosis compared to others. Our findings reveal a high prevalence of brucellosis among febrile patients and highlight a need for implementing appropiate tests, public awareness activities and vaccination of animals to control and eliminate the disease

    Barriers to access to visceral leishmaniasis diagnosis and care among seasonal mobile workers in Western Tigray, Northern Ethiopia: A qualitative study

    No full text
    Ethiopia bears a high burden of visceral leishmaniasis (VL). Early access to VL diagnosis and care improves clinical prognosis and reduces transmission from infected humans; however, significant obstacles exist. The approximate 250,000 seasonal mobile workers (MW) employed annually in northwestern Ethiopia may be particularly disadvantaged and at risk of VL acquisition and death. Our study aimed to assess barriers, and recommend interventions to increase access, to VL diagnosis and care among MWs

    Field suitability and diagnostic accuracy of the Biocentric open real-time PCR platform for plasma-based HIV viral load quantification in Swaziland

    No full text
    Viral load (VL) testing is being scaled up in resource-limited settings. However, not all commercially available VL testing methods have been evaluated under field conditions. This study is one of a few to evaluate the Biocentric platform for VL quantification in routine practice in Sub-Saharan Africa

    Field Evaluation of Near Point of Care Cepheid GeneXpert HIV-1 Qual for Early Infant Diagnosis

    No full text
    Access to point-of-care HIV testing shortens turn-around times, time to diagnosis and reduces loss to follow-up hence minimizing barriers to early linkage to care and treatment among HIV infected infants. Currently samples for early infant HIV diagnosis are sent to centralized testing facilities which are few and located only at specific regions in Kenya. However, there are Point of Care (POC) early infant diagnosis [EID] technologies elsewhere such as SAMBA and ALERE-Q that are yet to be evaluated in Kenya despite the urgent need for data to inform policy formulation regarding EID. The Cepheid GeneXpert HIV-1 Qual (GeneXpert) technology for POC EID offers a great opportunity to minimize HIV associated morbidity, mortality and loss to follow-up through decentralization of early infant HIV testing to the clinics. This technology also allows for same-day results thus facilitating prompt linkage to care

    Anthropology in public health emergencies:what is anthropology good for?

    No full text
    Recent outbreaks of Ebola virus disease (2013-2016) and Zika virus (2015-2016) bring renewed recognition of the need to understand social pathways of disease transmission and barriers to care. Social scientists, anthropologists in particular, have been recognised as important players in disease outbreak response because of their ability to assess social, economic and political factors in local contexts. However, in emergency public health response, as with any interdisciplinary setting, different professions may disagree over methods, ethics and the nature of evidence itself. A disease outbreak is no place to begin to negotiate disciplinary differences. Given increasing demand for anthropologists to work alongside epidemiologists, clinicians and public health professionals in health crises, this paper gives a basic introduction to anthropological methods and seeks to bridge the gap in disciplinary expectations within emergencies. It asks: 'What can anthropologists do in a public health crisis and how do they do it?' It argues for an interdisciplinary conception of emergency and the recognition that social, psychological and institutional factors influence all aspects of care

    Cost and affordability of non-communicable disease screening, diagnosis and treatment in Kenya: Patient payments in the private and public sectors

    No full text
    The prevalence of non-communicable diseases (NCDs) is rising in low- and middle-income countries, including Kenya, disproportionately to the rest of the world. Our objective was to quantify patient payments to obtain NCD screening, diagnosis, and treatment services in the public and private sector in Kenya and evaluate patients' ability to pay for the services

    Stockouts of HIV commodities in public health facilities in Kinshasa: Barriers to end HIV

    No full text
    Stockouts of HIV commodities increase the risk of treatment interruption, antiretroviral resistance, treatment failure, morbidity and mortality. The study objective was to assess the magnitude and duration of stockouts of HIV medicines and diagnostic tests in public facilities in Kinshasa, Democratic Republic of the Congo. This was a cross-sectional survey involving visits to facilities and warehouses in April and May 2015. All zonal warehouses, all public facilities with more than 200 patients on antiretroviral treatment (ART) (high-burden facilities) and a purposive sample of facilities with 200 or fewer patients (low-burden facilities) in Kinshasa were selected. We focused on three adult ART formulations, cotrimoxazole tablets, and HIV diagnostic tests. Availability of items was determined by physical check, while stockout duration until the day of the survey visit was verified with stock cards. In case of ART stockouts, we asked the pharmacist in charge what the facility coping strategy was for patients needing those medicines. The study included 28 high-burden facilities and 64 low-burden facilities, together serving around 22000 ART patients. During the study period, a national shortage of the newly introduced first-line regimen Tenofovir-Lamivudine-Efavirenz resulted in stockouts of this regimen in 56% of high-burden and 43% of low-burden facilities, lasting a median of 36 (interquartile range 29-90) and 44 days (interquartile range 24-90) until the day of the survey visit, respectively. Each of the other investigated commodities were found out of stock in at least two low-burden and two high-burden facilities. In 30/41 (73%) of stockout cases, the commodity was absent at the facility but present at the upstream warehouse. In 30/57 (54%) of ART stockout cases, patients did not receive any medicines. In some cases, patients were switched to different ART formulations or regimens. Stockouts of HIV commodities were common in the visited facilities. Introduction of new ART regimens needs additional planning

    Inter-rater and intrarater reliability of the South African Triage Scale in low-resource settings of Haiti and Afghanistan

    No full text
    The South African Triage Scale (SATS) has demonstrated good validity in the EDs of Médecins Sans Frontières (MSF)-supported sites in Afghanistan and Haiti; however, corresponding reliability in these settings has not yet been reported on. This study set out to assess the inter-rater and intrarater reliability of the SATS in four MSF-supported EDs in Afghanistan and Haiti (two trauma-only EDs and two mixed (including both medical and trauma cases) EDs)
