Novel coronaviruses are respiratory-transmitted infections, mainly transmitted by droplet and close contact, and there is now also concern about the possibility of aerosol transmission. The process of viral infection is mainly due to the high affinity between the virus and the ACE2 receptor in the respiratory tract, which enables transmission and causes illness. However, it has been found that in some isolated cases, despite good respiratory protection, if the conjunctiva is not adequately protected, the virus may also invade the body through the conjunctiva and can also cause morbidity. So the mucosal route is also a concern. So the current clinical protection for the new coronavirus, on the one hand, you have to wear a tighter mask, and you also have to wear goggles to reduce the contamination of the conjunctiva from droplets and reduce the chance of morbidity. Of course, evidence of transmission through the conjunctiva, or how infection occurs through the conjunctiva, still needs to be further studied. Source: Dr. Yurai
