According to a study by the University of Hong Kong, the new strain of corona virus is 100 times more contagious than severe acute respiratory syndrome (SARS) and avian influenza.
Laboratory tests have shown that the density of SARS-Cov-2 virus, the corona virus that causes Covid-19 pneumonia, is much thicker than SARS virus in the upper respiratory tract and conjunctiva, cells. mucosa on eye surface, according to the South China Morning Post.
The study was conducted under the direction of Dr. Michael Chan Chi-wai from the Hong Kong University School of Public Health (HKU). Mr. Chi-wai is one of the leading researchers in the world.
A study showing that coronavirus can infect people through the eyes is published in the latest issue of The Lancet Respiratory Medicine.
“We grew tissue taken from the human respiratory and eye systems in the laboratory to study SARS-Cov-2 and compare it with SARS and H5N1,” said Chi-wai.
“We found that SARS-Cov-2 spreads more easily than SARS in the conjunctiva and upper airways, with a viral density about 80 to 100 times thicker.”
This explains why Covid-19 is more infectious than SARS and the eye is an important way to spread the disease.
The study reinforces the advice of not touching your eyes and washing your hands often to avoid getting infected.
HKU scientists previously discovered that corona virus can survive up to 7 days on surfaces like stainless steel and plastic.
“Although there are signs that the Covid-19 epidemic is gradually becoming more stable in Hong Kong, the situation in other parts of the world is still serious. There are still many new cases being reported every day in Russia and Europe. We should not be subjective.
The team’s findings also point to the importance of providing adequate protective equipment for health workers. In addition to N95 masks and protective clothing, specialized glasses are indispensable.
