Can you catch the coronavirus from a mosquito that has already bitten somebody else?

As summer approaches and the bugs that can bite or sting you are reborn, the Centers for Disease Control and Prevention has declared that it’s unlikely that mosquitos and ticks can spread the coronavirus.

“At this time, CDC has no data to suggest that this new coronavirus or other similar coronaviruses are spread by mosquitoes or ticks,” the CDC reports. 

The World Health Organization echoed that sentiment on its web page dedicated to addressing ongoing myths related to COVID-19. 

“To date there has been no information nor evidence to suggest that the new coronavirus could be transmitted by mosquitoes,” the WHO said. “The new coronavirus is a respiratory virus which spreads primarily through droplets generated when an infected person coughs or sneezes, or through droplets of saliva or discharge from the nose.” 

COVID-19 is most easily spread from person-to-person—and primarily by people standing within six feet of each other through “respiratory droplets produced when an infected person coughs, sneezes, or talks.”

It is also possible that people can get COVID-19 by touching a surface or object that has the virus on it and then touching their face—but it is not the primary way the virus spreads. 

“There are no reports of any spread of coronavirus to humans by mosquitoes,” Dr. Mary Schmidt, an infectious disease and internal medicine specialist, told Fox News. “If this was a route of transmission, we would have seen it in the Middle East, where the Middle East Respiratory Syndrome (MERS) caused by the coronavirus has been present for 6 years.”

Schmidt continued by saying, “In order for this to happen in real life, the mosquitoes would have to acquire the virus during feeding, the virus then undergoes replication in the gut tissue, disseminates to the secondary sites of replication, including the salivary glands, and is ultimately released into the arthropod’s salivary secretions, where it may be inoculated into the skin and cutaneous vasculature of the host (human) during subsequent feeding.”
