Recency assays use one or more biomarkers to identify whether HIV infection in a person is recent (usually within a year or less) or longstanding. Recency assays have been used to estimate incidence in representative cross-sectional surveys and in epidemiological studies to better understand the pat...terns and distributions of new and longstanding HIV infections.
This technical guidance outlines best practices regarding the appropriate use of HIV recency assays for surveillance purposes and updates 2011 technical guidance from the World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) on the use of HIV recency assays.

I examine the effectiveness of donors in targeting the highest burden of malaria in the Democratic Republic of Congo when health information structure is fragmented. I exploit local variations in the burden of malaria induced by mining activities as well as financial and epidemiological data from he...alth facilities to estimate how local aid is matching local health needs. Using a regression discontinuity design, I find significant but quantitatively small variations in aid to health facilities located within mining areas. Comparing local aid with the additional cost of treatment and prevention associated with the increased risk of malaria transmission, I find suggestive evidence that local populations with the highest burden of the disease receive a proportionately lower share of aid compared to neighbouring areas with reduced exposure to malaria infection. The evidence of disparities in the allocation of aid for malaria supports the view that donors may have inaccurate information about local population needs.

Epi Info™ is a public domain suite of interoperable software tools designed for the global community of public health practitioners and researchers. It provides for easy data entry form and database construction, a customized data entry experience, and data analyses with epidemiologic statistics, ...maps, and graphs for public health professionals who may lack an information technology background. Epi Info™ is used for outbreak investigations; for developing small to mid-sized disease surveillance systems; as analysis, visualization, and reporting (AVR) components of larger systems; and in the continuing education in the science of epidemiology and public health analytic methods at schools of public health around the world.

The following protocol has been designed to investigate the extent of infection, as determined by seropositivity in the general population, in any country in which COVID-19 virus infection has been reported. Each country may need to tailor some aspects of this protocol to align with public health, l...aboratory and clinical systems, according to capacity, availability of resources and cultural appropriateness. However, using a standardized protocol such as this one below, epidemiological exposure data and biological samples can be systematically collected and shared rapidly in a format that can be easily aggregated, tabulated and analyzed across many different settings globally for timely estimates of COVID-19 virus infection severity and attack rates, as well as to inform public health responses and policy decisions. This is particularly important in the context of a novel respiratory pathogen, such as COVID-19 virus

This first online course is geared at helping healthcare workers in diagnosing and managing all aspects of dengue in order to avoid complications and fatalities.
This course was developed with a comprehensive vision. It is divided into seven modules that include:
Epidemiological informatio...n on dengue,
Pathophysiology of clinical manifestations,
Clinical and differential diagnosis,
Severity classification,
Recommendations for the management of dengue according to its severity and
Managing patients with comorbidities.

Cancer is an emerging public health problem in sub-Saharan Africa due to population growth, ageing and westernisation of lifestyles. In this piece, we use data from Mozambique over a 50-year period to illustrate cancer epidemiological trends in low-income and middle-income countries to hypothesise ...potential circumstances and factors that could explain changes in cancer burden and to discuss surveillance weaknesses and potential improvements. This epidemiological transition deserves increasing policy attention.

Ethiopia faces unprecedented public health risks with over 17.4 million people in need of health assistance due to a compounded security, epidemiological, environmental and socio-economic hardships throughout the country. Specifically, the prolonged drought and localized conflicts have negatively im...pacted public health systems, whose access has become severely hindered because of physical constraints, infrastructure, equipment damages, lack of available healthcare workforce and negative coping mechanisms resulting from livelihoods deterioration. Whereas the World Health Organization (WHO) assistance has been critical to coordinate humanitarian efforts in affected areas, additional efforts are required in the coming months to address ongoing epidemic outbreaks and support the recovery process in conflict-affected areas (Afar, Amhara, Tigray and Gambelia) that are now accessible.

The household transmission investigation is a case-ascertained prospective study of all identified household contacts of a laboratory confirmed 2019-nCoV infection (see 2.2 Study population). It is intended to provide rapid and early information on the clinical, epidemiological and virological chara...cteristics of 2019-nCoV.
There are three primary objectives of this household transmission study:
To better understand the extent of transmission within a household by estimating the secondary infection rate for household contacts at an individual level, and factors associated with any variation in the secondary infection risk.
To characterize secondary cases including the range of clinical presentation, risk factors for infection, and the extent and fraction of asymptomatic infections.
To characterize serologic response following confirmed 2019-nCoV infection (highly encouraged, but optional depending on laboratory capacity and resources)
