Vertically infected Aedes aegypti excrete infectious arboviruses in saliva
These findings suggest that vertical transmission may be an underestimated mechanism which provides a potential route by which Ae. aegypti can become infective independently of biting a viremic host, thereby contributing to arbovirus persistence and spread. The presence of infected male progeny also demonstrates that vertically transmitted viruses can persist in mosquito populations even in individuals that do not blood-feed.
