Yellow Fever Virus in Mosquitoes from Rainforest Bordering Manaus, Brazil, 2022

Emerg Infect Dis. 2025 Apr;31(4):851-854. doi: 10.3201/eid3104.240108.

Abstract

We detected yellow fever virus in Haemagogus mosquitoes collected in 2022 in an Amazon rainforest bordering Manaus, Brazil. The viral genome sequence occupied a basal position within the South American I genotype 1E lineage. Our findings reinforce the Amazon Basin as a source for yellow fever virus re-emergence.

Keywords: Amazon basin; Brazil; Haemagogus; Yellow fever virus; entomological surveillance; mosquitoes; outbreak; rainforest; sylvatic vectors.
