Classical rabies caused by RABV occurs worldwide besides some isolated countries and Western Europe that are regarded rabies free. Carnivores, especially of the canidae family represent the principal reservoir species and are responsible for the maintenance of the infectious cycle and hence for the ...presence of the disease (see Epidemiology of rabies). While wildlife rabies maintained by different reservoirs hosts predominantly occurs in the Northern hemisphere, canine rabies is by far more important for public health in the developing world.

Leishmaniasis is a vector-borne disease with a broad global distribution and an increasing number of recorded cases worldwide. However, it is still one of the world's most neglected diseases. Over the last decades, the disease has been found to expand geographically with a global increase of cases o...f visceral and cutaneous leishmaniasis increasing the public health problems associated with the disease epidemics. The reported range expansion of the diseases has been associated with range expansions of vector populations in response to climate change. Leishmaniasis is caused by protozoan parasites of the genus Leishmania. The transmission can either be zoonotic and/or anthroponotic through the bite of an infected female phlebotomine sandfly. In Eurasia and Africa, all vector-competent sandfly species belong to the genus Phlebotomus. Cutaneous leishmaniasis (CL) is the most common form of leishmaniasis. In the ‘old world’, it is caused by five currently recognized Leishmania species: L. major, L. tropica and L. aethiopica (being main causative parasites) as well as L. infantum and L. donovani. Visceral leishmaniasis (VL), another common and more severe form of leishmaniasis, is only associated with the Leishmania species L. infantum and L. donovani. The specific Leishmania species cause different clinical symptoms in humans.

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).

This project aimed to reduce the risk of vector-borne infection with Chagas disease by
controlling triatomine bugs, the vectors transmitting the parasite of Chagas disease, and
establishing an epidemiological surveillance system with community participation.
A 7.7 magnitude earthquake struck at 04:17 local time on 6 February 2023, with its epicentre located in Pazarcık district
in Kahramanmaraş province, Türkiye. Over 1200 aftershocks have since been reported. These are Türkiye’ s most powerful
earthquakes since 1939
Gambiense human African trypanosomiasis is a deadly infectious disease affecting West and Central Africa, South Sudan and Uganda, and transmitted between humans by tsetse flies. The disease has caused several major epidemics, the latest one in the 1990s. Thanks to recent innovations such as rapid di...agnostic tests for population screening, a single-dose oral treatment and a highly efficient vector control strategy, interruption of transmission of the causative parasite is now within reach. If indeed gHAT has an exclusively human reservoir, this could even result in eradication of the disease. Even if there were an animal reservoir, on the basis of epidemiological data, it plays a limited role. Maintaining adequate postelimination surveillance in known historic foci, using the newly developed tools, should be sufficient to prevent any future resurgence.

Chagas disease (CD) is an anthropozoonosis caused by the protozoan parasite Trypanosoma cruzi, that affects about 6–8 million people worldwide (1) a...nd causes approximately 50,000 deaths per year. Another 65–100 million people are living in areas at risk for infection worldwide (2–4). Even though over a century has passed since its discovery, CD remains one of the leading public health problems for most Latin American countries

Recency assays use one or more biomarkers to identify whether HIV infection in a person is recent (usually within a year or less) or longstanding. Recency assays have been used to estimate incidence in representative cross-sectional surveys and in epidemiological studies to better understand the pat...terns and distributions of new and longstanding HIV infections.
This technical guidance outlines best practices regarding the appropriate use of HIV recency assays for surveillance purposes and updates 2011 technical guidance from the World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) on the use of HIV recency assays.

The World Health Organization (WHO) recognizes the challenges countries face for maintaining their COVID-19 response while addressing competing public health challenges, conflicts, climate change and economic crises.
It remains critical for national programmes to continue to offer testing for COVI...D-19 in line with three main objectives: reduce morbidity and mortality through linkage to prompt care and treatment, reduce onward transmission and track the evolution of the epidemic and the virus

Note technique. Les centres de traitement de choléra fournissent des soins hospitaliers aux patients atteints de choléra
pendant les épidémies. Une prise en charge de qualité et l’isolement des patients atteints du choléra sont
essentiels pour prévenir les décès et aider à lutter con...tre la propagation de la maladie. Traditionnellement,
ces structures sont appelées centres de traitement du choléra (CTC) et unités de traitement du choléra (UTC).
Les CTC sont généralement de grandes structures mises en place au niveau central (zones urbaines, par
exemple), tandis que les UTC sont des structures plus petites, installées en périphérie (zones périurbaines ou
rurales, par exemple). Les CTC/UTC peuvent être mis en place en tant que structures indépendantes dans
des tentes ou à l’intérieur de bâtiments existants ou dans des unités sanitaires. Quelle que soit la structure,
les principes décrits dans ce document doivent être respectés.

an increased risk of disease transmission and epidemics. This
technical note explains why hygiene promotion is important in
emergencies and describes how to carry it out.
