Since March, the COVID-19 pandemic has impacted operations and required a different approach to communication with communities.
UNHCR communication channels have been rapidly enhanced and enlarged to ensure the continued provision of vital health and protection information.

This clinical practice guideline was developed in order to provide recommendations for the management of critically ill adult patients with COVID-19 in intensive care units (ICUs).
The COVID-19 pandemic has had an unprecedented impact on health care systems that, in many instances, worsened the already existing assistance gaps. When it comes to Latin America and Central America, this challenge adds to the consequences mass mobilizations have had in recent years, which have exc...eeded the national capacities to provide prompt assistance and social protection, particularly in the health care field. This pandemic has a direct impact on people on the move since the movement restriction policies and the lockdown and social distancing measures have reduced their ability to insert themselves into economic activities that were already precarious in many cases. Consequently, they have less access to food, housing, medicines and other essential consumer goods, and fewer possibilities of getting to their countries of destinati

This document describes the essential interventions in mental health and psychosocial support (MHPSS) that should be developed on an intersectoral basis in countries and communities. Its frame of reference is the Inter-Agency Standing Committee (IASC) intervention pyramid for MHPSS services. The pyr...amid shows different levels of support, ranging from social considerations, safety, and basic needs, to the provision of specialized services for the management of more severe conditions, as well as the probable volume of demand at each established level.

In the Region of the Americas, the leishmaniases are a group of diseases caused by various species of Leishmania, which cause a set of clinical syndromes in infected humans that can involve the skin, mucosa, and visceral organs. The spectrum of clinical disease is varied and depends on the interacti...on of several factors related to the parasite, the vector, and the host. Cutaneous leishmaniasis is the form most frequently reported in the Region and nearly 90% of cases present single or multiple localized lesions. Other cutaneous clinical forms, such as disseminated and diffuse cutaneous leishmaniasis, are more difficult to treat and relapses are common. The mucosal form is serious because it can cause disfigurement and severe disability if not diagnosed and treated early on. Visceral leishmaniasis is the most severe form, as it can cause death in up to 90% of untreated people.

In South and Central America, lymphatic filariasis (LF) is caused by Wuchereria bancrofti, which is transmitted by Culex quinquefasciatus, the only vector species in this region. Of the seven countries considered endemic for LF in the Americas in the last decade, Costa Rica, Suriname and Trinidad a...nd Tobago were removed from the World Health Organization list in 2011. The remaining countries, Brazil, Dominican Republic, Guyana and Haiti, have achieved important progress in recent years. Brazil was the first country in the Americas to stop mass drug administration (MDA) and to establish post-MDA surveillance. Dominican Republic stopped MDA in all LF-endemic foci: La Ciénaga and Southwest passed the third Transmission Assessment Survey (TAS) and the Eastern focus passed TAS-1 in 2018. Haiti passed the TAS and interrupted transmission in >80% of endemic communes, achieving effective drug coverage. Guyana implemented effective coverage in MDAs in 2017 and 2018 and in 2019 scaled up the treatment for 100% of the geographical region, introducing ivermectin in the MDA in order to achieve LF elimination by the year 2026. The Americas region is on its way to eliminating LF transmission. However, efforts should be made to improve morbidity management to prevent disability of the already affected populations.

Chagas disease (CD) is a neglected tropical disease, endemic in Latin America, but due to migration and environmental changes it has become a global public health issue.
Objective
To estimate the prevalence of Chagas disease in pregnant women and the vertical transmission of the disease.
Methods
Observational studies were identified from eight electronic databases, and details on study design, population and prevalence of Chagas disease were extracted. The data... were pooled using a random-effects model, and choropleth maps were created based on geopolitical regions and countries.

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.

Chagas disease affects approximately 6 million people, mainly in Latin America. Less than 1% of affected individuals receive proper antiparasitic treatment, and current drugs are inadequate to fight the entire spectrum of the disease. Against this background, Novartis is pursuing an end-to-end appro...ach, with activity on three fronts: drug discovery, clinical research and health system strengthening.

Smallpox eradication was certified in 1980. Mpox has been endemic in Central and West African countries since it was first detected in 1958 . It is a zoonosis; cases are often found close to tropical rainforests where various animals carry the orthopoxvirus that causes the disease. In endemic countr...ies, most mpox infections in humans result from a primary animal-to-human transmission. Human-to-human transmission can result from close contact with respiratory secretions, skin lesions of an infected person, or recently contaminated objects. Transmission can also occur via the placenta from mother to fetus or through close contact during and after birth.
