The WHO webpage on cholera provides an overview of the disease, its causes, and prevention strategies. Cholera is an acute diarrheal infection caused by the bacterium Vibrio cholerae, typically spread through contaminated food or water. It remains a significant global health issue, particularly in a...reas with poor water and sanitation infrastructure.

One of the many gender inequities in the health and care workforce that COVID-19 has exposed is around the fit and design of Personal Protective Equipment (PPE). The rapid onset and scale of COVID-19 led to shortages of PPE in most countries, causing preventable infection and mortality among healthc...are workers and others on the front lines. Even though most health workers are women, manufacturing specifications for medical PPE are usually drawn up based on the male body and there have been many reports of PPE not designed for women's bodies. WGH undertook a global research project to document the challenges women health workers have faced.

This 3 minutes and 24 second animation describes Dengue transmission, infection and the different symptoms associated with this disease. Also, the animation gives additional information about the habits of this mosquito. This video illustrates several important preventative measures, both inside the... house and the environmental sanitation around the house, to avoid being bitten by the mosquitoes. Let's all work together to stop the spread of dengue!

Chagas disease is a tropical parasitic infection transmitted by crawling, blood-sucking insects (kissing bugs). You may have flu-like symptoms or none at all. But the disease can lead to life-threatening complications. With prompt treatment, most people with Chagas disease, also known as American tr...ypanosomiasis, recover fully.

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.
