Scientists at the National University Hospital of Singapore assessed whether the coronavirus can be transmitted through tears and found that such risks of transmission are low.
With the spread of the epidemic worldwide, people are generally panic about the spread of the virus. Current research has shown that the virus is transmitted through contact and droplets, but it is uncertain whether it can be transmitted through other body fluids.
To this end, researchers at the National University Hospital of Singapore assessed whether the coronavirus can be transmitted through tears. In this study, the researchers started with 17 patients with coronavirus symptoms and collected tear samples after they recovered 20 days later.
Analysis of the tear fluid showed that the virus could not be detected in the tear fluid throughout the onset of symptoms. At the same time, researchers also took samples from the throat and nose. It was found that although the patient's tears were free of the virus, their nose and throat were full of the virus.
Not long ago, experts found that about 1-3% of coronavirus carriers will develop red eye or conjunctivitis. The American Academy of Ophthalmology explains: "If you see someone whose eyes are pink, don't panic. It doesn't mean that person is infected with a coronavirus."
But health officials believe that about 1% to 3% of coronavirus carriers will develop viral red eye or conjunctivitis. Viruses can be transmitted by contact with liquids or liquid-carrying substances in the eyes of an infected person
Based on this, Dr. Sonal Tuli, a spokesman for the American Academy of Ophthalmology, suggested: "It's important to remember that despite many concerns about coronavirus, common sense precautions can greatly reduce your infection risk. So, wash your hands often, pay attention to the hygiene of contact lenses, and avoid touching or rubbing your nose, mouth, especially your eyes. "
