Policy brief.
Globally, one in five people with HIV are unaware of their status, despite considerable scale up of HIV testing, treatment and prevention services. Many of those unreached by HIV testing services (HTS) are from key populations, partners of people with HIV and, in Eastern and southern ...Africa, men and young people. Improving the availability, accessibility, friendliness and quality of services is important to address these testing gaps.
At the same time, tools and interventions that increase the demand for HTS are needed to reach people who are uninformed about HTS options and advances in treatment and prevention, people who are not motivated to seek HTS and those who are hesitant to test because of fear of an HIV diagnosis or other reasons.

Global efforts to eradicate dracunculiasis have continued to progress, with only 542 cases reported in 2012, as compared with 1058 in 2011. It is a long thread-like worm. It is transmitted exclusively when people drink water contaminated with parasite-infected water fl eas. It is now found in some o...f the most deprived regions of Africa.

Key facts
Buruli ulcer is a chronic debilitating disease caused by an environmental Mycobacterium ulcerans.
At least 33 countries with tropical, subtropical and temperate climates have reported Buruli ulcer in Africa, South America and Western Pacific regions.
It often affects the skin an...d sometimes bone and can lead to permanent disfigurement and long-term disability.
The mode of transmission is not known and there is no prevention for the disease.

Since the last situation report on the multi-country outbreak of cholera was published on 1 June 2023 (covering data reported until 15 of May), no new country reported a cholera outbreak. In total, 24 countries have reported cases since the beginning of 2023. The WHO African Region remains the most ...affected region with 14 countries reporting cholera cases since the beginning of the year. The overall capacity to respond to the multiple and simultaneous outbreaks continues to be strained due to the global lack of resources, including shortages of the Oral Cholera Vaccine (OCV) and cholera supplies, as well as overstretched public health and medical personnel, who are dealing with multiple parallel disease outbreaks and other health emergencies. Based on the large number of outbreaks and their geographic expansion, as well as a lack of vaccines and other resources, WHO continues to assess the risk at global level as very high.

Smallpox eradication was certified in 1980. Mpox has been endemic in Central and West African countries since it was first detected in 1958 . It is a zoonosis; cases are often found close to tropical rainforests where various animals carry the orthopoxvirus that causes the disease. In endemic countr...ies, most mpox infections in humans result from a primary animal-to-human transmission. Human-to-human transmission can result from close contact with respiratory secretions, skin lesions of an infected person, or recently contaminated objects. Transmission can also occur via the placenta from mother to fetus or through close contact during and after birth.

Since the last situation report on the multi-country outbreak of cholera was published on 6 July 2023 (covering data reported until 15 of June), and as of 15 July 2023, one new outbreak of cholera was reported from India on 15 May 2023. In total, 25 countries have reported cases since the beginning ...of 2023. The WHO African Region remains the most affected region with 14 countries reporting cholera cases since the beginning of the year.

The conditionality of this recommendation is largely driven by the current higher unit cost of pyrethroid-PBO ITNs compared
to pyrethroid-only LLINs and therefore the uncertainty of their cost-effectiveness. Furthermore, as PBO is less wash-resistant
than pyrethroids, its bioavailability declines ...faster over the three-year estimated life of an ITN; therefore, the added impact of
pyrethroid-PBO ITNs over that of pyrethroid-only LLINs may decline over time. The evidence comes from two sites in
eastern Africa with pyrethroid resistance and not from other geographies where transmission levels and vector characteristics
may vary. PBO acts by inhibiting certain metabolic enzymes, primarily oxidases, and so are likely to provide greater protection
than pyrethroid-only LLINs where mosquitoes display mono-oxygenase-based insecticide resistance mechanisms.

The World Health Organization's malaria fact sheet provides an overview of malaria, a life-threatening disease caused by Plasmodium parasites transmitted through the bites of infected female Anopheles mosquitoes. It highlights that malaria is preventable and curable, yet remains a significant glo...bal health challenge. Key statistics from 2023 indicate an estimated 263 million malaria cases and 597,000 deaths worldwide, with the WHO African Region bearing the majority of this burden. The fact sheet details transmission methods, symptoms, at-risk populations, diagnostic approaches, treatment options—including the use of artemisinin-based combination therapies (ACTs)—and preventive measures such as insecticide-treated nets (ITNs) and indoor residual spraying (IRS). It also discusses the impact of malaria on vulnerable groups like children under five and pregnant women, and outlines WHO's global response strategies aimed at reducing malaria incidence and mortality rates.

Rabies remains an under-reported neglected zoonosis with a case-fatality rate of almost 100% in humans and animals. Dog-mediated human rabies causes tens of thousands of human deaths annually despite being 100% preventable. More than 95% of human cases are caused by the bite of a rabies-infected dog.... Dog-mediated human rabies disproportionately affects rural communities, particularly children, and economically disadvantaged areas of Africa and Asia, where awareness of the disease and access to appropriate post-exposure prophylaxis (PEP) can be limited or nonexistent.

Provision of water and sanitation and good hygiene practices play an essential role in protecting human health during all disease outbreaks, including during Ebola Virus Disease (EVD) outbreaks. This question and answer document provides practical, evidence-based recommend...ations on minimum requirements and best practices for water, sanitation, hygiene (WASH). It was originally developed in 2014 during the West Africa Ebola Outbreak and has been updated in 2021 to reflect lessons learned and new operational research data. The key recommendations on WASH remain the same.

Schistosomiasis is widely recognized as a disease that is socially determined. An
understanding of the social and behavioural factors linked to disease transmission and
control should play a vital role in designing policies and strategies for schistosomiasis
prevention and control. To this must b...e added the awareness that schistosomiasis is
also a disease of poverty. It still survives in poverty-stricken, remote areas where there
is little or no safe water or sanitation, and health care is scarce or non-existent. For
a variety of complex reasons, many of which are addressed in this book, the disease
is particularly prevalent in sub-Saharan Africa, and persists in certain areas of rural
China. This concern for human behaviour in an environment of poverty echoes the
concerns of the new research priority for “diseases of poverty” identified by the
Special Programme for Research & Training in Tropical Diseases.
