Abstract Yellow fever virus (YFV) was isolated from Haemagogus leucocelaenus mosquitoes during an epizootic in 2001 the Rio Grande do Sul State southern Brazil. In October 2008, a yellow outbreak reported there, with nonhuman primate deaths and human cases. This latter led to intensification of surveillance measures for early detection YFV support vaccination programs. We report entomologic 2 municipalities that recorded deaths. Mosquitoes were collected at ground level, identified,...
Due to the risk of severe vaccine-associated adverse events, yellow fever vaccination in Brazil is only recommended areas considered at for disease. From September 2008 through June 2009, two outbreaks previously unvaccinated populations resulted 21 confirmed cases with 9 deaths (case-fatality, 43%) southern state Rio Grande do Sul and 28 11 (39%) Sao Paulo state. Epizootic non-human primates were reported before during outbreak. Over 5.5 million doses vaccine administered most affected...
Yellow fever (YF) is an arboviral disease which endemic to Brazil due a sylvatic transmission cycle maintained by infected mosquito vectors, non-human primate (NHP) hosts, and humans. Despite the existence of effective vaccine, recent sporadic YF epidemics have underscored concerns about vector surveillance, as very little known their spatial distribution. Here, we model map environmental suitability YF's main vectors in Brazil, Haemagogus spp. Sabethes spp., use human population NHP data...
Abstract The natural transmission cycle of Yellow Fever (YF) involves tree hole breeding mosquitoes and a wide array nonhuman primates (NHP), including monkeys apes. Some Neotropical (howler monkeys, genus Alouatta ) develop fatal YF virus (YFV) infections similar to those reported in humans, even with minimum exposure the infection. Epizootics wild may be indicating YFV circulation, surveillance such outbreaks wildlife is an important tool help prevent human In 2001, activities successfully...
In Brazil, epizootics among New World monkey species may indicate circulation of yellow fever (YF) virus and provide early warning risk to humans. Between 1999 2001, the southern Brazilian state Rio Grande do Sul initiated surveillance for YF in non-human primates inform vaccination human populations. Following a outbreak, we analyzed epizootic data assessed vaccine coverage, timeliness implementation unvaccinated From October 2008 through June 2009, was confirmed 67 municipalities State;...
Primates play an important role in ecosystem functioning and offer critical insights into human evolution, biology, behavior, emerging infectious diseases. There are 26 primate species the Atlantic Forests of South America, 19 them endemic. We compiled a dataset 5,472 georeferenced locations native 1 introduced species, as hybrids genera Callithrix Alouatta. The includes 700 communities, 8,121 single occurrences 714 estimates population sizes, covering most natural forest types tropical...
In recent decades, waves of yellow fever virus (YFV) from the Amazon Rainforest have spread and caused outbreaks in other regions Brazil, including Cerrado, a savannah-like biome through which YFV usually moves before arriving at Atlantic Forest. To identify vectors involved maintenance semiarid environments, an entomological survey was conducted after confirmation (YF) epizootics peak dry season Cerrado areas state Minas Gerais. total, 917 mosquitoes 13 taxa were collected tested for...
Despite the considerable morbidity and mortality of yellow fever virus (YFV) infections in Brazil, our understanding disease outbreaks is hampered by limited viral genomic data. Here, through a combination phylogenetic epidemiological models, we reconstructed recent transmission history YFV within different epidemic seasons Brazil. A suitability index based on highly domesticated Aedes aegypti was able to capture seasonality reported human infections. Spatial modeling revealed spatial...
A Febre Amarela (FA) é uma doença infecciosa aguda. No Brasil, a FA tem caráter sazonal, ocorrendo frequentemente entre os meses de janeiro abril, quando fatores ambientais propiciam o aumento da abundância dos vetores. Há diversos relatos sobre mortalidade primatas devido à FA, em especial do gênero Alouatta, mas há escassa informação disponível para verificar e quantificar danos causados às populações por eventos desta natureza. O presente estudo busca avaliar impacto surto ocorrido 2008...
The 2021 re-emergence of yellow fever in non-human primates the state Rio Grande do Sul (RS), southernmost Brazil, resulted death many howler monkeys (genus Alouatta) and led to declare a Public Health Emergency State Importance, despite no human cases reported. In this study, near-complete genomes virus (YFV) recovered from outbreak were sequenced examined aiming at better understanding phylogenetic relationships spatio-temporal dynamics distribution. Our results suggest that most likely...
