Can mosquitoes transmit 2019 novel coronavirus (COVID-19)?

This is a common question since mosquitoes are everywhere and they seem to bite everyone

Can these bloodsuckers spread COVID-19 to people when they bite?

A new study by Kansas State University researchers is the first to confirm that SARS-CoV-2 cannot be transmitted to people by mosquitoes.

From the study:

"Three widely distributed species of mosquito; Aedes aegyptiAe. albopictus and Culex quinquefasciatus, representing the two most significant genera of arbovirus vectors that infect people, were tested."

"We demonstrate that even under extreme conditions, SARS-CoV-2 virus is unable to replicate in these mosquitoes and therefore cannot be transmitted to people even in the unlikely event that a mosquito fed upon a viremic host."

What CAN mosquitoes spread?

One common group of mosquitoes, called Culex, spread West Nile virus, which is the most prevalent mosquito-borne disease in Los Angeles County. Another group of L.A. County mosquitoes, called Aedes mosquitoes, have the potential to spread Zika, dengue fever, yellow fever, and chikungunya.
