The focus of this fact sheet is on the four main causes of acute bacterial meningitis:
Neisseria meningitidis (meningococcus)
Streptococcus pneumoniae (pneumococcus)
Haemophilus influenzae
Streptococcus agalactiae (group B streptococcus)

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.

To avoid a reversal of progress from the adverse impacts of the COVID-19 pandemic, new knowledge and lessons from successful programmatic innovations are urgently needed to improve TB prevention and care. Experience can provide evidence for innovative approaches and strategies to mainta...in and scale up high-quality TB services. WHO therefore called for case studies on programmatic innovations that address emerging challenges in TB prevention and care during the pandemic in order to collect and disseminate the findings to the TB community. Between November 2020 and February 2021, a total of 23 case studies relevant to the call were accepted from 19 countries in the six regions of WHO. The lessons learnt from these country activities to ensure the continuity of essential services like TB care in the face of the crippling crisis may also inform strategies for minimizing the impact of future emerging pathogens on health services.

The overall threat posed by Omicron largely depends on four key questions: (i) how transmissible the variant is; (ii) how well vaccines and prior infection protect against infection, transmission, clinical disease and death; (iii) how virulent the variant is compared to other varian...ts; and (iv) how populations understand these dynamics, perceive risk and follow control measures, including public health and social measures (PHSM).

The COVID-19 pandemic has led to large increases in healthcare waste, straining under resourced healthcare facilities and exacerbating environmental impacts from solid waste. This report quantifies the additional COVID-19 healthcare waste generated, describes current healthcare waste management syst...ems and their deficiencies, and summarizes emerging best practices and solutions to reduce the impact of waste on human and environmental health. The recommendations included in the report build on actions in the WHO manifesto for a healthy recovery from COVID-19: prescriptions and actionables for a healthy and green recovery. They target the global, national and facility levels to promote a “win–win” scenario for COVID-19 PPE use, testing and vaccinations that are safe and support environmental sustainability.

The marathon to eradicate polio is on its final lap: the world is more than 99% of the way to success. After millennia of living with poliovirus and suffering the paralysis it causes, today nearly all the world’s people live in polio-free countries; two of the three strains of wild poliovirus (WPV...) have been eradicated. Some 20 million people are walking who would have been paralysed had it not been for the efforts of national governments and health workers. If eradicating polio has been a marathon, the finishing line is in sight.

Cases of monkeypox (MPX) acquired in the EU have recently been reported in nine EU Member States (Austria, Belgium, France, Germany, Italy, Portugal, Spain, Sweden, and the Netherlands).
Monkeypox (MPX) does not spread easily between people. Human-to-human transmission occurs through close contact ...with infectious material from skin lesions of an infected person, through respiratory droplets in prolonged face-to-face contact, and through fomites. The predominance, in the current outbreak, of diagnosed human MPX cases among men having sex with men (MSM), and the nature of the presenting lesions in some cases, suggest transmission occurred during sexual intercourse

Surveillance mondiale de la leishmaniose: 2021, évaluation de l’impact de la pandémie de COVID-19
The aims of this report are to update the results of the GHO leishmaniasis indicators reported by Member States to WHO up to 2021, to describe specific indicators of gender and age distribution, re...lapses, the AmBisome® donation programme, selected outbreaks, case fatality rates for visceral leishmaniasis (VL, also known as kala-azar), rates of co-infection with HIV and VL and the burden of post-kala-azar dermal leishmaniasis (PKDL). This report also describes the Kala-azar Elimination Programme in South-East Asia and adverse events after administration of antileishmanial drugs.

Schistosomiasis is a helminthic infection and one of the neglected tropical diseases (NTDs). It is caused by blood flukes of the genus Schistosoma. It is an important public health problem, particularly in poverty-stricken areas, especially those within the tropics and subtropics. It is estimated th...at at least 236 million people worldwide are infected, 90% of them in sub-Saharan Africa, and that this disease causes approximately 300,000 deaths annually. The clinical manifestations are varied and affect practically all organs. There are substantial differences in the clinical presentation, depending on the phase and clinical form of schistosomiasis in which it occurs. Schistosomiasis can remain undiagnosed for a long period of time, with secondary clinical lesion. Here, we review the clinical profile of schistosomiasis. This information may aid in the development of more efficacious treatments and improved disease prognosis.

Yaws is a disfiguring non-venereal disease caused by infection with the spirochaete. Treponema pallidum subspecies pertenue which is closely related to the causative agent of syphilis and those of the other endemic treponematoses, bejel and pinta. The disease is endemic in certain areas of the World... Health Organization (WHO) African, South-East Asia and Western Pacific regions. Of the neglected tropical diseases identified for elimination and eradication, yaws is one of two diseases targeted for eradication. In 1949, the Second World Health Assembly adopted resolution WHA2.36, which addresses yaws, bejel and pinta as major public health problems that need attention.
