There are 4 main forms of the disease: visceral leishmaniasis (VL, also known as kala-azar); post-kala-azar dermal leishmania...sis (PKDL); cutaneous leishmaniasis (CL); and mucocutaneous leishmaniasis (MCL). While cutaneous leishmaniasis is the most common form of the disease, visceral leishmaniasis is the most serious and can be fatal if untreated. Additionally, leishmaniasis can be classified as anthroponotic or zoonotic depending on whether the natural reservoir of the parasite is human or animal.
This report updates global epidemiological information on VL and CL to 2015, based on the main indicators published in the GHO, as of 1st September 2017.

Die neuen Podcast-Folgen werden dienstags gegen 17 Uhr veröffentlicht. Neben Christian Drosten, dem Leiter der Virologie an der Berliner Charité, ist Sandra Ciesek, Direktorin des Instituts für Medizinische Virologie am Universitätsklinikum Frankfurt am Main, ein regelmäßiger Gesprächsgast.
...Seit Ende Februar 2020 beantwortet Prof. Dr. Christian Drosten (Leiter der Virologie an der Berliner Charité) Fragen zur aktuellen Situation, erklärt Zusammenhänge und schildert, wie er diese Monate persönlich erlebt. Anfang September kam Prof. Dr. Sandra Ciesek (Leiterin der Virologie des Universitätsklinikums Frankfurt) als Gesprächsgast dazu.

These guidelines provide new and updated recommendations on the use of point-of-care testing in children under 18 months of age and point-of-care tests to monitor treatment in people living with HIV; the treatment monitoring algorithm; and timing of antiretroviral therapy (ART) among people living w...ith HIV who are being treated for tuberculosis.
New recommendations launched today outline key new actions that countries can take to improve the delivery of HIV testing, treatment and care services by providing greater options for differentiated approaches such as, supporting HIV treatment start in the community, ensuring that children are diagnosed and treated early, and that viral load treatment monitoring is more accessible, focused and triggers clinical action

Operation update 01/04/2022
9 June 2022. This report presents an update of monkeypox confirmed cases in the European Union/European Economic Area (EU/EEA) and worldwide
Since the notification of the first two confirmed cases of Vibrio cholerae O1 in the greater Port-au-Prince area on 2 October 2022, to 22 October 2022, the Haitian Ministry of Health (Ministère de la Santé Publique et de la Population, MSPP per its French acronym), reported a total of 2,243 suspec...ted cases, including 219 confirmed cases, 1,415 hospitalized suspected cases, and 55 registered deaths.
On 20 October 2022, the Dominican Republic Ministry of Public Health confirmed the first imported case of cholera in the country.

Since the notification of the first two confirmed cases of Vibrio cholerae O1 in the greater Port-au-Prince area on 2 October 2022, to 14 January 2023, the Haitian Ministry of Health (Ministère de la Santé Publique et de la Population, MSPP per its French acronym), reported a total of 24,232 suspe...cted cases in 10 departments of the country, including 1,742 confirmed cases, 20,505 hospitalized suspected cases, and 483 registered deaths. This represents an increase in the last 7 days of 5% in suspected cases (N=1,188), 11% in confirmed cases (N=166) and 4% in deaths (N=19). As of 14 January 2023, 9 departments have confirmed cases (Artibonite, Centre, Grand-Anse, Nippes, Nord, Nord-Ouest, Ouest, Sud and Sud-Est). To date, the case fatality rate among suspected cases is 2.0%.

Epidemiological Update
Dengue
7 February 2020
Situation summary
In the Region of the Americas, between epidemiological week (EW) 1 and EW 521 of 2019, a total of 3,139,335 cases of dengue have been reported (321.58 cases per 100,000 population), including 1,538 deaths. Of the total cases, 1,367,...353 (43.6%) were laboratory-confirmed and 28,169 (0.9%) were classified as severe dengue. The case-fatality rate was 0.049%.

This review focusses on the interactions between the etiologic agent of Chagas disease, Trypanosoma cruzi, and its triatomine vector. The flagellate mainly colonizes the intestinal tract of the insect. The effect of triatomines on trypanosomes is indicated by susceptibility and refractoriness phenom...ena that vary according to the combination of the strains. Other effects are apparent in the different regions of the gut. In the stomach, the majority of ingested blood trypomastigotes are killed while the remaining transform to round stages. In the small intestine, these develop into epimastigotes, the main replicative stage. In the rectum, the population density is the highest and is where the infectious stage develops, the metacyclic trypomastigote. In all regions of the gut, starvation and feeding of the triatomine affect T. cruzi. In the small intestine and rectum, starvation reduces the population density and more spheromastigotes develop. In the rectum, feeding after short-term starvation induces metacyclogenesis and after long-term starvation the development of specific cells, containing several nuclei, kinetoplasts and flagella. When considering the effects of T. cruzi on triatomines, the flagellate seems to be of low pathogenicity. However, during stressful periods, which are normal in natural populations, effects occur often on the behaviour, eg, in readiness to approach the host, the period of time before defecation, dispersal and aggregation. In nymphs, the duration of the different instars and the mortality rates increase, but this seems to be induced by repeated infections or blood quality by the feeding on infected hosts. Starvation resistance is often reduced by infection. Longevity and reproduction of adults is reduced, but only after infection with some strains of T. cruzi. Only components of the surface coat of blood trypomastigotes induce an immune reaction. However, this seems to act against gut bacteria and favours the development of T. cruzi.

As of 14 December 2021, a total of 19 laboratory-confirmed human rabies cases has been reported in South Africa for 2021. The cases are from Eastern Cape, KwaZuluNatal and Limpopo provinces. In addition, four probable rabies cases were reported from KwaZulu-Natal and the Eastern Cape provinces. A pr...obable case of rabies is defined as a person who has had a history of contact with a suspected or confirmed rabid animal and has developed an acute encephalitis with hyperactivity and paralytic signs and symptoms that progressed and resulted in death, usually by cardiac or respiratory failure, typically within ten days.

Issue Brief 33: Since 21 June 2023, 57 024 new cholera cases, including 399 new death have been reported worldwide (European Center for Disease Prevention and Control). In total, 25 countries have reported cases since the beginning of 2023. The major underlying causes of potential outbreaks are poor... environmental infastructure, lack of health care services, lack of save water and sanitation as well as increase population movement. Climate change becomes an additional trigger, as extreme climate events like cyclones,floods and droughts reduce access to clean water and create an ideal environment for cholera to thrive. The overall capacity to respond to the multiple outbreaks is obstructed by a global lack of resources.
This issue brief provides an overview of the current outbreaks, treatment guidelines, information material, countries strategies and more.

Since fighting between the Sudanese Armed Forces (SAF) and the Rapid Support Forces (RSF) erupted in mid-April, an estimated 6.3 million people have fled their homes, taking refuge inside and outside the country, with children representing about half of the people displaced. Sudan is now the country... with the largest number of displaced people in the world as prior to the fighting there were 3.7 million people internally displaced in Sudan. It is also now the country with the largest child displacement crisis in the world. ACLED estimates that more than 10,400 people have been killed since the fighting broke out in April, of which about 1,300 killings happened between 30 September and 27 October.
