Technical Update
Areas of Africa endemic for Buruli ulcer (BU), caused by Mycobacterium ulcerans, also have a high prevalence of human immunodeficiency virus (HIV), with adult prevalence rates between 1% and 5% (Maps). However, there is limited information on the prevalence of BU–HIV coinfection.... Preliminary
evidence suggests that HIV infection may increase the risk of BU disease (1–3). In the Médecins Sans Frontières project in Akonolinga, Cameroon, HIV prevalence was approximately 3–6 times higher among BU patients than the regional estimated HIV prevalence (2). Similarly in Benin and Ghana, BU
patients were 8 times and 3 times respectively more likely to have HIV infection than those without BU (1, 3). Further study is needed to clarify this association and enhance knowledge about the prevalence ofBU–HIV coinfection in endemic areas.

Cryptococcal disease is one of the most common opportunistic infections among people living with advanced HIV disease and is a major contributor to severe illness, morbidity, and mortality, particularly in sub-Saharan Africa.
These guidelines update the recommendations that were first released i...n 2018 on diagnosing, preventing, and managing cryptococcal disease. In response to important new evidence that became available in 2021, these new guidelines strongly recommend a single high dose of liposomal amphotericin B as part of the preferred induction regimen for the treatment of cryptococcal meningitis in people living with HIV. This simplified regimen - a single high dose of liposomal amphotericin B paired with other standard medicines (flucytosine and fluconazole) - is as effective as the previous WHO standard of care, with the benefits of lower toxicity and fewer monitoring demands.
The objective of these guidelines is to provide updated, evidence-informed recommendations for treating adults, adolescents and children living with HIV who have cryptococcal disease. These guidelines are aimed at HIV programme managers, policymakers, national treatment advisory boards, implementing partners and health-care professionals providing care for people living with HIV in resource-limited settings with a high burden of cryptococcal disease.

Every year pollution causes 9 million deaths—1 in every 6 deaths worldwide, according to a Lancet Commission on pollution and health.
While the number of deaths caused by household air pollution a...nd water pollution decreased from 2015 to 2019, overall deaths remain roughly the same because of a 7% increase in deaths caused by air pollution and toxic chemical pollution.

Cases of human monkeypox are rarely seen outside of west and central Africa. There are few data regarding viral kinetics or the duration of viral shedding and no licensed treatments. Two oral drugs, brincidofovir and tecovirimat, have been approved for treatment of smallpox and have demonstrated eff...icacy against monkeypox in animals. Our aim was to describe the longitudinal clinical course of monkeypox in a high-income setting, coupled with viral dynamics, and any adverse events related to novel antiviral therapies.

The aim of this toolkit is to guide countries on how to best estimate their current burden of dengue by combining existing data from dengue surveillance systems with on-going research efforts to measure the community burden
of dengue.
Arsenical monotherapies were previously very successful for treating human African trypanosomiasis (HAT).
Melarsoprol resistance emerged as early as the 1970s and was widespread by the late 1990s.
Melarsoprol resistance represents the only example of widespread drug resistance in HAT patients wher...e the genetic mechanism has been established.
The current goal of elimination of HAT as a public health problem by 2020 may be undermined by the emergence and spread of resistance to current or new drugs.
Insights into potential resistance mechanisms for current and new drugs will facilitate predictions of the likelihood of resistance and will also facilitate rational approaches to minimizing, monitoring, and tackling the future emergence of resistance.

Leptospirosis is a bacterial zoonotic disease of worldwide importance, though relatively neglected in many African countries including sub Saharan Africa that is among areas with high burden of this disease. The disease is often mistaken for other febrile illnesses such as dengue, malaria, rickettsi...oses and enteric fever. Leptospirosis is an occupational disease likely to affect people working in environments prone to infestation with rodents which are the primary reservoir hosts of this disease. Some of the populations at risk include: sugarcane plantation workers, wetland farmers, fishermen and abattoir workers. In this study we investigated the prevalence of antibodies against Leptospira among sugarcane plantation and factory workers, fishing communities as well as among rodents and shrews in domestic and peridomestic environments within the study areas.

In 2014, an estimated 40 million women of reproductive age were infected with Schistosoma haematobium, S. japonicum and/or S. mansoni. In both 2003 and 2006, the World Health Organization (WHO) recommended that all schistosome-infected pregnant and breastfeeding women be offered treatment, with praz...iquantel, either individually or during treatment campaigns. In 2006, WHO also stated the need for randomized controlled trials to assess the safety and efficacy of such treatment. Some countries have yet to follow the recommendation on treatment and many programme managers and pregnant women in other countries remain reluctant to follow the recommended approach.

Training in monitoring and epidemiological assessment of mass drug administration for eliminating lymphatic filariasis: learners’ guide. World Health Organization.
Diets are changing everywhere, and the burden of disease associated with unhealthy diets is a worldwide concern. Measurement and monitoring of diets across countries and population groups is critical. However, there are no harmonized metrics for tracking how the healthfulness of diets around the wor...ld is evolving.
This report assesses the validity, usefulness and fitness for purpose of existing healthy diet metrics as global and national monitoring indicators, presents a comparative assessment of selected healthy diet metrics and discusses priorities and opportunities to improve diet monitoring. This report is an important first step of the Healthy Diets Monitoring Initiative to respond to the need for developing healthy diets metrics for assessing and monitoring diets at national and global level.

Building on the 2021 Interim guidance, this second version and update, incorporates the lessons and feedback from the hepatitis pilots that successfully demonstrated the feasibility of measuring hepatitis B and C impact targets to demonstrate elimination, whilst highlighting challenges caused by hig...h disease burden in some countries, as well as delays in reaching mortality targets due to the long natural history of disease progression to liver cirrhosis and hepatocellular carcinoma.
The path to elimination provides a framework with 3 levels of achievements for which WHO certification is available. Each stepwise progression from bronze to silver to gold tiers will promote an iterative expansion of prevention, diagnosis and treatment services for viral hepatitis services and strengthen measurement systems to support attainment of the 2030 elimination goals.
This updated version also includes changes, clarifications and new guidance on alternative measurement approaches for country validation of elimination. Through the validation process, WHO and partners continue to provide country support for strengthening health system capacity and patient-centred services that respect and protect the human rights of people living with viral hepatitis and ensures meaningful engagement of communities in the national, regional and global viral hepatitis response.

Cardiovascular diseases, principally ischemic heart disease (IHD), are the most important cause of death and disability in the majority of low- and lower-middle-income countries (LLMICs). In these countries, IHD mortality rates are significantly greater in individuals of a low socioeconomic status (...SES).
Three important focus areas for decreasing IHD mortality among those of low SES in LLMICs are (1) acute coronary care; (2) cardiac rehabilitation and secondary prevention; and (3) primary prevention. Greater mortality in low SES patients with acute coronary syndrome is due to lack of awareness of symptoms in patients and primary care physicians, delay in reaching healthcare facilities, non-availability of thrombolysis and coronary revascularization, and the non-affordability of expensive medicines (statins, dual anti-platelets, renin-angiotensin system blockers). Facilities for rapid diagnosis and accessible and affordable long-term care at secondary and tertiary care hospitals for IHD care are needed. A strong focus on the social determinants of health (low education, poverty, working and living conditions), greater healthcare financing, and efficient primary care is required. The quality of primary prevention needs to be improved with initiatives to eliminate tobacco and trans-fats and to reduce the consumption of alcohol, refined carbohydrates, and salt along with the promotion of healthy foods and physical activity. Efficient primary care with a focus on management of blood pressure, lipids and diabetes is needed. Task sharing with community health workers, electronic decision support systems, and use of fixed-dose combinations of blood pressure-lowering drugs and statins can substantially reduce risk factors and potentially lead to large reductions in IHD. Finally, training of physicians, nurses, and health workers in IHD prevention should be strengthened.
