Coronavirus can enter the body through the eyes, claim scientists, casting doubt on the efficacy of wearing just a mask as protection.
SARS-CoV-2, the strain that causes Covid-19, has been found to latch onto ACE-2 receptors, which are known as the "gateway" into cells inside the body.
These receptors are found in the respiratory tract and the lungs, which is where coronavirus attacks after microbes from an infected person are breathed in by another person.
However a team led by Johns Hopkins University School of Medicine have now found the eyes also produce ACE-2, making them a target for the deadly virus.
