SARS-CoV-2: is it present in the conjunctiva?

The Orthocoronavirinae family was discovered in the 1960s. These are enveloped viruses with positive single-stranded RNA, and their genome size varies approximately between 26 32 kb, being largest for an RNA virus. In Mexico, first reported case that of a person from Italy. Taking this as day 1, cases have been increasing and, at time writing article, there were 133,974 infected people 15,944 deaths. conjunctiva has proposed route entry SARS-CoV-2. However, search coronavirus genetic material tear samples, patients who did not show conjunctivitis negative presence viral material, only one positive, both samples. Negative results SARS-CoV-2 tears conjunctival secretions could indicate virus does replicate epithelia, but be present undetectable amounts, which rule out it can transmitted through conjunctiva.
