The routs of SARS-CoV-2 infection and transmission in eyes. Eyes are important portals of entry for virus. After SARS-CoV-2 infected and replicated in eyes, it will be transmitted through two ways: one is outward transmission, eye secretions, or tears with virus contaminate the hands, and then there is a risk of transmission of the virus through hands. Another route is inward transmission. If the virus infected person though eyes, conjunctival secretions, and tears can flow into the mouth through the nasopharyngeal tube then reach the lungs or gastrointestinal tract and more infections occur.
