[Vaccination coverage in children under one year of age in Minas Gerais state, Brazil].

The scope of this article is to analyze vaccination coverage rates in children under one year of age during the period from 2015 to 2020 in the state of Minas Gerais (MG). It involved an ecological, time-series study on vaccination coverage in children under 1 year of age, considering the 28 Regional Health Management/Superintendencies (GRS/SRS) of MG as the unit of analysis. The following immunobiological vaccine coverage was analyzed: Bacillus Calmette and Guérin, human rotavirus, pneumococcal 10, pentavalent, meningococcus C, yellow fever, and polio vaccines.

Absence of yellow fever virus circulation in wildlife rodents from Brazil.

Yellow fever (YF), caused by the yellow fever virus (YFV), is an emerging viral zoonosis that affects humans and non-human primates (NHP). In South America, YF is naturally maintained through enzootic/sylvatic cycles involving NHPs and mosquitoes (Haemagogus and Sabethes). In this study, we retrospectively analyzed wildlife rodents to better understand their role in a potential alternative YF sylvatic cycle.

Re-Emergence of Yellow Fever in Brazil during 2016-2019: Challenges, Lessons Learned, and Perspectives.

Yellow fever (YF) is a re-emerging viral zoonosis caused by the (YFV), affecting humans and non-human primates (NHP). YF is endemic in South America and Africa, being considered a burden for public health worldwide despite the availability of an effective vaccine. Acute infectious disease can progress to severe hemorrhagic conditions and has high rates of morbidity and mortality in endemic countries.

Circulation of vaccinia virus in southern and south-eastern wildlife, Brazil.

We evaluated 345 wild animals from southern and south-eastern Brazil to understand their role in vaccinia virus (VACV) transmission cycle. VACV DNA was detected in rodents, marsupials, chiroptera and cingulate, expanding the knowledge of VACV host range in wildlife that could potentially act as source of infection in rural and urban areas.

Silent Orthohantavirus Circulation Among Humans and Small Mammals from Central Minas Gerais, Brazil.

New World orthohantaviruses are emerging RNA viruses that cause hantavirus cardiopulmonary syndrome (HCPS). These viruses are a burden to public health around the world with a lethality rate of around 60%. In South America, rodents of Sigmodontinae subfamily are the main reservoirs of orthohantaviruses.
