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.

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.

Leprosy/Hansen disease is a chronic infectious disease primarily impacting the skin and peripheral nerves. If left untreated, leprosy can have long-term consequences, including deformities and disabilities, which are associated with stigma. Leprosy is one of the 21 neglected tropical diseases (NTDs)..., a group of conditions prevalent in tropical regions. In the “WHO Roadmap for Neglected Tropical Diseases 2021–2030”, leprosy, human African trypanosomiasis (HAT) and onchocerciasis are targeted for interruption of transmission. Acknowledging the growing necessity for establishing a process to verify the absence of new autochthonous leprosy cases, a technical guidance has been developed outlining a clear pathway, demarcating phases with
indicators and milestones leading towards the elimination of leprosy disease.

Ahead of World Malaria Day, the WHO Global Malaria Programme published a new operational strategy outlining its priorities and key activities up to 2030 to help change the trajectory of malaria trends, with a view to achieving the global malaria targets. The strategy outlines 4 strategic objectives ...where WHO will focus its efforts, including developing norms and standards, introducing new tools and innovation, promoting strategic information for impact, and providing technical leadership of the global malaria response.
In recent years, progress towards critical targets of the WHO Global technical strategy for malaria 2016-2030 has stalled, particularly in countries that carry a high burden of the disease. In 2022 there were an estimated 608 000 malaria-related deaths and 249 million new malaria cases globally, with young children in Africa bearing the brunt of the disease.
Millions of people continue to miss out on the services they need to prevent, detect, and treat malaria. Additionally, progress in global malaria control has been hampered by resource constraints, humanitarian crises, climate change and biological threats such as drug and insecticide resistance.
“A shift in the global malaria response is urgently needed across the entire malaria ecosystem to prevent avoidable deaths and achieve the targets of the WHO global malaria strategy,” notes Dr Daniel Ngamije, Director of the Global Malaria Programme. “This shift should seek to address the root causes of the disease and be centred around accessibility, efficiency, sustainability, equity and integration.”

Clinical management standard operating procedures.
Ebola virus disease (EVD) is a life-threatening multisystem illness associated with fever and gastrointestinal (GI) symptoms that frequently leads to hypovolaemia, metabolic acidosis, hypoglycaemia, and multi-organ failure. The prolonged 2013–201...6 EVD outbreak in West Africa allowed for an evolution of care such that by outbreak end many patients received individualized and optimized supportive care (oSoC), including volume resuscitation, symptom control, laboratory and bedside monitoring of glucose, electrolyte levels and organ dysfunction, as well as rapid detection and treatment of co-infections, potentially contributing to the downward trend in the case fatality rate (CFR).
This guidance should serve as a foundation for oSoC that should be followed to ensure both the best possible chance for survival and allow for reliable comparison of investigational therapeutic interventions as part of a randomized controlled trial. This guideline provides recommendations for the management of adults and children.
