Mosquitoes cannot transmit novel coronaviruses. The new coronavirus belongs to the genus β coronavirus, and its main transmission routes include the following: 1. The transmission of the virus is mainly through respiratory droplets and close contact. 2. Contact with virus-contaminated items. 3. Exposure to high concentrations of aerosols in relatively closed environments where there is a possibility of transmission via aerosols. 4. Since the new coronavirus can be isolated in feces and urine, attention should be paid to the possibility of contact or aerosol transmission due to environmental contamination. At present, the new coronavirus does not reproduce and store in mosquitoes, and naturally does not spread through mosquito bites. In order to avoid the infection of new coronavirus in our daily life, we need to wear masks correctly and scientifically, do not go in and out of relatively crowded places during the epidemic, pay attention to personal hygiene and do a good job of preventive disinfection.
