Onchocerciasis used to be an important public health problem in Africa, with over 37 million people infected and millions suffering from debilitating skin disease, terrible itching, impaired vision and
blindness. But the epidemiological situation has improved dramatically over the last two decades.... Community directed treatment with ivermectin has effectively brought the disease under control in most endemic areas where onchocerciasis is no longer a public health risk.

Countries are making progress toward the global goal of 95% of people living with HIV knowing their status by 2025. However, considerable gaps remain in achieving these goals globally. Men in high HIV burden settings and men from key populations in all settings are consistently less likely to know t...heir HIV status than women. Globally, 78% of men ages 15 years and older who are living with HIV are aware of their HIV status, compared with 86% of women with HIV of these ages.
Offering HIV testing services, including HIV self-testing, at formal and informal workplaces has emerged as an effective, acceptable and feasible approach for reaching men. A 2018 World Health Organization (WHO) and International Labour Organization (ILO) policy brief provides key guiding principles for HIVST implementation at workplaces. Building on the 2018 policy brief, this brief captures early experience with HIVST implementation at workplaces and discusses emerging approaches of sustainable financing that can be adapted for HIV self-testing at workplaces.
The primary audiences for this policy brief are ministries of health and labour, national HIV programmes, employers’ organizations, workers’ organizations (labour unions), enterprises, implementing partners, including civil society organizations, and health insurance agencies.

Sexual exploitation, sexual abuse and sexual harassment (SEAH) violate the rights and wellbeing of the people we serve and the people with whom we serve. Such behaviours are directly in opposition to WHO’s values and our abiding responsibility to do no harm. WHO uses the umbrella term “sexual mi...sconduct” to encompass the full spectrum of prohibited and unwanted behaviour of a sexual nature (including rape and sexual assault) as described in WHO’s 2023 Policy for preventing and addressing sexual misconduct (1). This is because all such acts are prohibited – whether perpetrated by WHO’s own personnel or by implementing partners – and therefore constitute misconduct. The term sexual misconduct is also easier to communicate and translate, as
victims and survivors do not always understand the complicated acronyms and definitions used by the United Nations (UN) and the humanitarian sector. However, we use the terms sexual misconduct and SEAH interchangeably as required when we interact with UN and other stakeholders.

Chromoblastomycosis (CBM), represents one of the primary implantation mycoses caused by melanized fungi widely found in nature. It is characterized as a Neglected Tropical Disease (NTD) and mainly affects populations living in poverty with significant morbidity, including stigma and discrimination.
Snakebite envenoming constitutes a serious medical condition that primarily affects residents of rural communities in Africa, Asia, Latin America, and New Guinea. It is an occupational, environmental, and domestic health hazard that exacerbates the already impoverished state of these communities. Co...nservative estimates indicate that, worldwide, more than 5 million people suffer snakebite every year, leading to 25,000–125,000 deaths, while an estimated 400,000 people are left with permanent disabilities.

The major neglected tropical diseases, Taenia solium taeniosis/cysticercosis and schistosomiasis caused by Schistosoma mansoni or S. haematobium are presumed to be widely distributed in Africa. Taenia solium taeniosis/ cysticercosis has been reported as an emerging disease in different regions of Af...rica [1, 2], but currently the exact distribution remains unclear. Reported prevalences of T. solium taeniosis and cysticercosis in African countries are not extensive and are further complicated by the lack of ‘gold standard’ tests for diagnosis.

The WHO continuously reviews available data on SARS-CoV-2 variants of concern. For this version, the global epidemiological
situation of the COVID-19 pandemic as of 21 January 2022 – at a time when the Omicron VOC had been identified in 171
countries across all six WHO Regions and was rapidly re...placing Delta worldwide – was considered Omicron has a substantial growth advantage, higher secondary attack rates and a higher observed reproduction number than Delta.
There is now significant evidence that immune evasion contributes to the rapid spread of Omicron. Other factors may be a shorter
serial interval (by about 0.8 to 1.2 days compared to Delta) and potential increased intrinsic transmission fitness . There is
growing evidence that with Omicron, there is lower vaccine effectiveness (VE) against infection and symptomatic disease soon after vaccination compared to Delta. There is also evidence of accelerated waning of VE over time of the primary series against infection and symptomatic disease for the studied vaccines. Further studies are required to better understand the drivers of transmission and declining incidence in various settings. These factors include the intrinsic transmission fitness properties of the virus, degree of immune evasion, vaccination coverage and level of vaccine-derived and post-infection immunity, levels of social mixing and degree of application of public health and social measures (PHSM).

Rabies is fatal, vaccine-preventable disease responsible for an estimated 59,000 human deaths each year. Most cases are transmitted by dogs, and most deaths occur in underserved populations in Africa and Asia. Approximately 40% of deaths occur in children.
The epidemiology of the disease is mediated by the interaction of the parasite (trypanosome) with the vectors (tsetse flies), as well as with the human and animal hosts within a particular environment. Related to these interactions, the disease is confined in spatially limited areas called “foci..., which are located
in Sub-Saharan Africa, mainly in remote rural areas. The risk of contracting HAT is, therefore, determined by the possibility of contact of a human being with an infected tsetse fly. Epidemics of HAT were described at the beginning of the 20th century; intensive activities have been set up to confront the disease, and it was under control in the 1960s, with fewer than 5,000 cases reported in the whole continent.

Cervical cancer continues to be a significant public health problem and a major cause of premature mortality among women, disproportionately affecting the socioeconomically disadvantaged population in low- and middle-income countries (LMICs). In the absence of implementing the known evidence-based, ...cost-effective interventions, the number of deaths per year is projected to reach approximately 416 000 globally in 2035. It was estimated in 2020 that 32% of incident cervical cancer cases and 34% of cervical cancer deaths in the world occurred in the 11 Member States of the WHO South-East Asia (SEA) Region. In 2020, 190 874 new cases and 116 015 deaths were estimated due to cervical cancer, which is the third commonest cancer in the Region

Rabies is a fatal viral zoonosis and serious public health problem.1 All mammals are believed to be susceptible to the disease, and for the purposes of this document, use of the term animal refers to mammals. The disease is an acute, progressive encephalitis caused by viruses in the genus Lyssavirus....
2 Rabies virus is the most important lyssavirus globally. In the
United States, multiple rabies virus variants are maintained in wild mammalian reservoir populations such as raccoons, skunks, foxes, and bats. Although the United States has been declared free from transmission of canine rabies virus variants, there is always a risk of reintroduction of these variants.The rabies virus is usually transmitted from animal to animal through bites. The incubation period is
highly variable. In domestic animals, it is generally 3 to 12 weeks, but can range from several days to months, exceeding 6 months.8 Rabies is communicable during the period of salivary shedding of rabies virus. Experimental and historic evidence documents that dogs, cats, and ferrets shed the virus for a few days prior to the onset of clinical signs and during illness. Clinical signs of rabies are variable and include inappetance, dysphagia, cranial nerve deficits, abnormal behavior, ataxia, paralysis, altered vocalization, and seizures. Progression to death is rapid. There are currently no known effective rabies antiviral drugs.

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.

Improving the survival chances and quality of life of women, newborns, and children remains an urgent global challenge. Since 2012, substantial progress has been made in reducing maternal and under-5 deaths, and a only handful of countries are on target to meet the SDG targets in 2030. Yet, 5 millio...n children still die each year under the age of 5, and nearly half of those are newborns less than a month old. Worse still, the global maternal mortality ratio is going in the wrong direction.
A Decade of Progress and Action for the Future will examine the tenacity and innovation that helped us make gains, the lessons learned through monitoring, country-led adaptation and leadership, analysis, and reflection, as well as the approaches we must take to reinvigorate the momentum and global commitment to improving maternal and child survival. Increasing coverage, strengthening the quality of care, and enhancing equity will be tantamount to our global progress.

Training in monitoring and epidemiological assessment of mass drug administration for eliminating lymphatic filariasis: learners’ guide. World Health Organization.
Chagas disease is currently endemic and also predicted to be at increased transmission risk under future climate change scenarios. Similarly, an expansion of areas in the United States at increased risk for Chagas disease transmission is also expected over the next several decades under climate chan...ge scenarios. Of particular interest is the predicted northern shift of triatomine species to central regions of the United States with historically unsuitable climates for T. cruzi vectors. The weight of evidence regarding the influences climate change may pose on T. cruzi vector species distributions demonstrates the sensitivity of Chagas disease transmission to future climate variability. In order to advance forecasts for the impact climate change may have on Chagas disease transmission in the Americas, it is imperative to
further develop, utilize, and perhaps combine predictive species distribution modeling approaches that integrate accurate, long term data on climate variables, vector species distributions, Chagas disease incidence, as well as other socio-ecological variables.

Integrating the prevention and control of noncommunicable diseases in HIV/AIDS, tuberculosis, and sexual and reproductive health programmes: implementation guidance
The application of digital health technology is growing at a rapid rate in Africa, with the goals of improving the delivery of healthcare services and more effectively reaching out to remote and underserved communities. The lack of enabling guidelines and standards across the continent, on the other... hand, makes it difficult to share data in a meaningful way across the continent.
Considering this, Africa Centres for Disease Control and Prevention (Africa CDC) established a task force of 24 members to provide expertise and guidance in the development of AU HIE guidelines and standards. Members of the task force were subject matter experts working in Africa and internationally on the collection, analysis, and exchange of health information. Some of these experts had been involved in previous consultations on defining Africa CDC’s health information systems strategy. A chairperson, co-chairperson, and secretary were elected to engage the task force members in different technical working groups.
