Eurosurveillance: Experimentally Infected Culex Mosquitoes Unable To Spread Zika

Credit Wikipedia


There has been a lot of speculation, and concern, that the ubiquitous Culex mosquito - which is a vector for West Nile Virus - might also be capable of transmitting the Zika virus.  

Previously we've seen reports suggesting that the Culex mosquito might be a competent vector (see Fiocruz: Zika Virus Experimentally Introduced Into Culex Mosquitoes), but their role (if any) in transmitting the virus remained unproven. 

But in July we saw an EID Journal Study on Culex pipiens and Aedes triseriatus Mosquito Susceptibility to Zika Virus which cast doubt on the ability of the Culex mosquito to harbor and transmit the virus.

Today, we've two more Rapid Communications published in the ECDC journal Eurosurveillance with similar findings.  Neither found experimentally infected Culex mosquitoes capable of transmitting the virus.
