While Covid-19 continues to evolve, wash your hands frequently. Covid-19 can enter the body through your eyes, if someone sneezes or coughs virus particles are in the air. It’s also possible to touch a surface, such as a door handle, that is contaminated with the virus and then touching your eye may become infected. Touching a contaminated surface and then touching your eye would be the worst because you could be exposed to the virus and a potential eye infection.
