Transovarial

· Aedes mosquitoes, for example, may acquire the virus from feeding on infected animals, and are capable of transovarial transmission (transmission of the virus from infected female mosquitoes to offspring via eggs), so new generations of infected mosquitoes may hatch from their eggs. ❋ Unknown (2000)

Infected female mosquitoes may also transmit the virus to the next generation of mosquitoes by transovarial transmission i.e. via its eggs, but the role of this in sustaining transmission of virus to humans has not yet been delineated. ❋ Unknown (1998)

Rodents are important reservoirs, but transovarial transmission also keeps the pathogen in the vector population. ❋ Unknown (1996)

Given that transovarial transmission following one gonotrophic cycle is likely rare in nature ❋ Andrew D. Haddow Et Al. (2009)

The burden of infected mosquitoes would continue to increase into the summer months as each successive generation of mosquitoes fed upon viremic amplification hosts, followed by increased transovarial transmission of the virus to their progeny. ❋ Andrew D. Haddow Et Al. (2009)
