Can Mosquitos or Ticks Spread COVID-19?

At this time, CDC has no data to suggest that this new coronavirus or other similar coronaviruses are spread by mosquitoes or ticks. The main way that COVID-19 spreads is from person to person. For a virus to pass to a person through a mosquito or other kind of insect bite—such as a tick bite—the virus must be able to replicate inside the mosquito or tick. Neither the new coronavirus nor any other type of coronavirus has been shown to do that.

Furthermore, mosquitoes are very genetically different from humans. “This makes it challenging for viruses to have the ability to infect both of us,” says Gallichotte. “We have different receptors on the surface of cells and different replication machinery inside our cells.”
