A new study by Singaporean scientists published in Ophthalmology shows that the transmission method of corona virus (SARS-CoV-2) following this path is almost impossible.

In the course of their work, experts from the National University Hospital of Singapore tested tears samples of 17 patients with COVID-19, from the time they had their first symptoms until they fully recovered (medium). average after 20 days)

Analysis showed that during the two weeks they were infected, SARS-CoV-2 was not in their tears.

Dr Ivan Cea, the lead author of the study, also took a sample from the back of the patient’s nose and throat for use as a control. While the patients’ tears were very clean, their nose and throat "tickled" SARS-CoV-2.

An indirect indicator that coronavirus is not spread by tear fluid is that only 1-3% of people with COVID-19 are found to have conjunctivitis. The authors concluded that their results, combined with data on low conjunctivitis data in patients with disease, showed that the risk of transmitting the virus through tears was extremely low.

Earlier, the Daily Mail page, Chelsey Earnest, an employee at the Life Care Center in Kirkland - the heart of Washington - said the eye was "the most important sign" in people with Covid-19, the viral diseases.

"It is a sign that I see in all patients," she said.

’They have eyes that look like they’re allergic. The whites of the eyes are not red. It’s like they have red circles outside their eyes. ’

She said the red circle around her eyes is the most important sign that a person is infected with the virus.
