In order for SARS-CoV-2 to enter a cell, “the cell has to have ACE2 on its surface so that the coronavirus can latch onto it and gain entry into the cell,” Duh says.

Not much research existed on ACE2 and the eye’s surface cells, he says. With the team’s findings, “We were really struck that ACE2 was clearly present in the surface cells of all of the specimens.” In addition, the researchers found that the eye’s surface cells also produce TMPRSS2, an enzyme that helps the virus enter the cell.

“all of this evidence together seems to suggest that there’s a good likelihood that the ocular surface cells are susceptible to infection by coronavirus.”

At the pesticide applicator education meetings we've been told that eyes are an entry point.
