DETROIT Michigan residents were very concerned about whether mosquitoes could spread the coronavirus (COVID-19) at the start of the pandemic. Mosquitoes can spread many dangerous diseases, but from the start of the COVID-19 outbreak, experts were confident they wouldnt be able to spread the SARS-CoV-2 virus. In the lab, researchers injected mosquitoes with the coronavirus, giving them a larger dose than they would naturally get from feeding on the blood of an infected person. In short, unlike the viruses that cause mosquito-borne illnesses, SARS-CoV-2 isnt able to complete the steps necessary to survive and be transmitted by mosquitoes. Even though mosquitoes cant carry COVID-19, they still pose a threat to transmit West Nile virus, Eastern Equine Encephalitis (EEE) and other illnesses.
