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)

The Cholera Q&A Fact Sheet provides essential information about cholera, including its causes, symptoms, treatment, and prevention. Cholera is an acute diarrheal disease caused by Vibrio cholerae, which spreads through contaminated water and food. It leads to rapid dehydration and can be fatal if un...treated. Symptoms range from mild diarrhea to severe dehydration, shock, and death.
Treatment primarily involves Oral Rehydration Therapy (ORT) to replace lost fluids, and in severe cases, intravenous fluids. Antibiotics are generally not recommended for mass treatment. Prevention focuses on safe drinking water, sanitation, hand hygiene, and proper food handling.
The document also discusses cholera vaccination, with three WHO-approved oral vaccines available. However, vaccines should be used alongside other control measures. The Global Task Force on Cholera Control (GTFCC) aims to eliminate cholera transmission in 20 countries by 2030 through improved sanitation, vaccination, and rapid outbreak response.

This paper examines determinants of one aspect of sexual behaviour – coital frequency – among 2188 married women in the Central African Re...public using a secondary analysis of data from the Demographic and Health Survey of 1994–95. Female genital cutting (or circumcision) is practised in the Central African Republic and self-reported circumcision status was included in the questionnaire enabling it to be examined as a possible determinant of coital frequency. Multiple logistic regression was used to find a subset of factors independently associated with coital frequency.
Decreased coital frequency was found in those who had longer duration of marriage, those who were not the most recent wife in a polygamous marriage and those who had more surviving children. Coital frequency was higher in more educated women and those not contracepting because they wanted to get pregnant. After adjusting for confounders no association between
female genital cutting and coital frequency was found. The extent to which women can control coital frequency in this culture is not known and fertility desires may override any negative effects of circumcision on sexual pleasure.
It was therefore not possible to draw conclusions about how female genital cutting affects a woman’s desire for sexual intercourse and consequently there is a need to develop research methods further to investigate this question.

One approach to development assistance for health, or health aid, emphasizes the ex ante selection of cost-effective health interventions, an approach that began with the World Development Report (1993) on Investing in Health and has since been adopted by the Effective Altruism community. But just h...ow much of health aid is cost-effective? In this paper, we examine projects in the Organisation for Economic Co-operation and Development (OECD) Creditor Reporting System, the standard dataset that measures and characterizes development assistance for health, for the
years 2019 to 2021, and count the number of projects that refer to interventions from a list of highly cost-effective interventions as defined by the Disease Control Priorities Project, third edition. This exploratory quantitative analysis indicates that 61% of projects used a key word/phrase of a costeffective intervention. There were 11.9 interventions mapped per project on average. There is little evidence that donors tailor the set of interventions to country income levels by cost-effectiveness.
Policymakers may benefit from reviewing the full portfolio of interventions covered by domestic and external resources.

WHO recommends that pre-exposure prophylaxis (PrEP) be offered as an additional prevention choice for HIV-negative individuals at substantial risk of HIV infection as part of combination prevention approaches.
HIV drug resistance has been rarely reported among PrEP users who tested HIV positive i...n randomized controlled trials or open-label studies. However, PrEP-selected HIV drug resistance could potentially negatively impact the effectiveness of treatment options among PrEP users who acquire HIV, since there is a potential for overlapping resistance profiles between antiretroviral drugs used for both PrEP and first-line antiretroviral therapy.

The global emergence of antimicrobial resistance (AMR) is posing a threat to human health. Putting resources into the containment of AMR – including surveillance – is one of the highest-yield investments a country can make to mitigate its impact. In 2015, WHO launched the Global Antimicrobial Re...sistance Surveillance System (GLASS), the first global collaborative effort to foster AMR surveillance in bacteria causing acute infections. As of December 2018, 71 countries are enrolled in GLASS. The aim of this report is to document participation efforts and outcomes across these countries, and highlight differences and constraints identified to date. This report follows on from the first GLASS Report – Early implementation 2016-17, published in January 2018, and drawing on data from GLASS first data call in 2017.

The following Emergency Response Plan for the COVID-19 pandemic seeks to set out activities that will be undertaken by humanitarian actors in Ukraine over the course of 2020 to respond to the public health impact of the epidemic – as well as the indirect, socio-economic impact on people’s well-b...eing, which will span across many areas. Given the extensive public exposure of the COVID-19 threat, the response will cover the whole of Ukraine, while providing a distinct focus on Donetska and Luhanska oblasts that have been ravaged by an armed conflict for the last six consecutive years. The planned COVID-19 response in the two conflict-affected oblasts will be treated as an annex to the current Humanitarian Response Plan for Ukraine

South Africa reported it fist case of COVID-19 on 5 March 2020. While the first cases were imported, local transmission has led to a rapid increase in the number of cases. As of 21 April 2020, more than 3,400 cases and 58 deaths had been confirmed. On 15 March, President Cyril Ramaphosa declared a n...ational state of disaster, and the government has since taken several measures to curb the spread of the virus, including closing borders, implementing strict social distancing measures and a 35-day nation-wide lockdown. These measures, along with the global economic shock caused by the pandemic, are expected to generate rising needs requiring an immediate and urgent response. Although South Africa is considered an upper-middle-income country, the amount of disparities—social, economic, and gender—make the country particularly vulnerable during this emergency.

HIV testing programmes need to ensure that all clients who test for HIV are provided with correct diagnoses. The accuracy of HIV testing is critical to prevent misdiagnosis, as the consequences of giving an incorrect test result can be serious for clients, HIV testing services, HIV programmes and pu...blic health.
With the evolution of global HIV epidemiology, HIV testing approaches must also evolve to maintain accuracy and efficiency in population-level diagnosis. Reports suggest that misdiagnosis of HIV status may occur when suboptimal testing algorithms and out-of-date testing strategies are used. As a result of changing epidemiology and declining HIV positivity in testing, WHO recommends all countries use a standard three-test strategy to ensure a PPV of at least 99%, minimizing false-positive misdiagnosis. The WHO-recommended HIV testing strategy, along with quality assurance measures such as retesting to verify a positive diagnosis prior to initiation of HIV treatment, is cost-effective as it prevents misdiagnosis and unnecessary initiation of costly lifelong treatment.
This implementation guide provides practical advice on switching to a three-test strategy and instituting other measures that can help national HIV programmes deliver high-quality, accurate HIV testing services and ensure that misdiagnosis is minimized.
