“…However, both field and experimental data remain too sparse and sometimes diverge [129,130] and more investigations are definitely needed so that these assumptions can be discussed on a solid basis. Overall, the risk of urban spread of YFV due to the presence of dense populations of Aaa mosquitoes in numerous urban centres where most of the inhabitants are nonimmune remains a concern in multiple countries in South America [62, [131][132][133][134].…”

“…aegypti have not been reported recently in South America (see the "Ecology of Yellow Fever Virus" section). However, the presence of dense populations of these mosquitoes in numerous urban centres where most of the inhabitants are nonimmune remains a concern in tropical/sub-tropical countries throughout South America [133,134], notably with the emergence of new variants showing increased epidemic potential such as the 1E sublineage of the South American genotype I [142].…”

“…In Brazil, the yellow fever virus (YFV) have been sporadically detected in human and non-human primates (NHPs) populations from the enzootic/endemic Northern (Amazon) and epidemic Central-Western regions during the second half of the 20 th century (Carrington and Auguste, 2013;Monath and Vasconcelos, 2015). Since the early 2000s, the virus has progressively expanded to the Southeastern and Southern Brazilian regions and in December 2016 began the largest epizootic/epidemic of sylvatic YF registered in the country over the last 50 years (Vasconcelos, 2010;Possas et al, 2018a;Possas et al, 2018b). Between December 2016 and June 2018, a total of 2,139 YF human cases were confirmed in all Southeastern Brazilian states of Minas Gerais (n = 997), São Paulo (n = 577), Rio de Janeiro (n = 307) and Espírito Santo (n = 258) with 735 deaths (case-fatality, 34%).…”

“…Sylvatic yellow fever (YF) cycles propagate the virus among monkeys with occasional transmission to humans, and are responsible for the majority of the human cases reported to the World Health Organization (WHO) . The risk for explosive urban YFV cycles becomes a concern when sylvatic YFV outbreaks occur near densely populated areas infested by Aedes aegypti . In such areas, YF control can be obtained through mosquito control and through human immunization.…”

“…1 The risk for explosive urban YFV cycles becomes a concern when sylvatic YFV outbreaks occur near densely populated areas infested by Aedes aegypti. 4,5 In such areas, YF control can be obtained through mosquito control and through human immunization. Unfortunately, vector control programs, while successful in the past, have been discontinued, and mosquito populations returning to high levels are now responsible for recurring outbreaks with cocirculation of multiple arboviruses including DENV, chikungunya virus (CHIKV), ZIKV, and YFV.…”
