A study conducted at the University of Hong Kong has shown that the eye is also a ‘main route’ for the coronavirus to enter the human body. The study found that the strain of coronavirus was 100 times more contagious than severe acute respiratory syndrome (SARS) and bird flu (H5N1).
Laboratory tests have shown that the coronavirus strain of SARS-Cov-2, which causes Covid-19, has higher virus levels in our upper trachea and conjunctiva (the surface of our eyes) than SARS.

The team, led by Michael Chan Chi-wai, is one of the first researchers to present evidence that coronaviruses can transmit from two entry points in the body. Their findings are published in a new issue of The Lancet Respiratory Medicine.
Earlier, university researchers had shown that coronaviruses can live up to seven days in plastic and stainless steel. This study re-establishes the need to avoid eye contact and frequent hand washing to avoid coronavirus infection.
The first coronavirus infection was reported in the Chinese city of Wuhan in late December. As of Thursday, the epidemic had infected more than 3.7 million people worldwide and killed more than 264,000, according to Johns Hopkins University.
