Arboviruses require a vertebrate host and a vector for transmission. This course of includes the localization of an contaminated host by haematophagous arthropods, which get contaminated throughout feeding and develop into competent for onward transmission. Pathogen-infected hosts could also be extra attractive for haematophagous arthropods, nevertheless it stays unclear whether or not arboviruses manipulate mosquito attraction to reinforce the chance of viral dissemination. Evidence means that host odorants (pores and skin volatiles) are key host cues to control the feeding motivation of haematophagous vectors. In this examine, Zhang et al. present that flaviviruses promote the proliferation of acetophenone-producing pores and skin commensal micro organism, which reinforces mosquito attraction and thus flavivirus transmission.
