Vertical Transmission of ZIKV in aedes aegypti

ABSTRACT: Vertical transmission, or pathogen transfer from mother to offspring, can facilitate persistence of emerging arboviruses, such as Zika virus (ZIKV), in mosquito populations. Understanding vertical transmission and the different environmental and temporal conditions that affect it is important to assess whether new outbreaks could occur without re-introduction of the virus. To determine the rate of vertical transmission for ZIKV, Ae. Aegypti females were fed on ZIKV infected blood, maintained under three temperature conditions (27℃, 30℃, and 33℃), and allowed to oviposit three times. Progeny were tested for virus presence at 3, 7, and 14 days after adult emergence. The overall vertical transmission rate was 6.5% (3.9 - 9.9). Vertical transmission was observed across all maternal temperatu
