Tears are a quick vector of corona infection


A scientific team at Johns Hopkins University in the United States said that the infection of the Corona virus can be transmitted through the eyes, which contain protein substances capable of catching the virus quickly, and that the virus can be transmitted through the tear fluid.
According to the scientists, the eyes contain a protein called “ACE-2”, which is responsible for the transmission of the virus, and that dropping small drops of sneezing or coughing from an infected person on the surface of the eye leads to infection, according to the British newspaper “Daily Mail”.

Scientists began their studies after people who were infected with the virus complained of eye irritation, and found that the ACE-2 protein found in the cornea of ​​the eye, and the edges between the cornea and the whites of the eye, would quickly catch the virus, calling it a description of the “gate of disease transmission.”

And led the scientific team Lingli Zhu, from the Department of Ophthalmology at Johns Hopkins University School of Medicine, who, along with his team, analyzed dozens of samples from the eyes of people with coronavirus, and found that the presence of ACE-2 protein, and another enzyme called TMPRSS2, in the same cell helps To reproduce the virus effectively.

“The virus can be found in tears, which greatly help in the transmission of infection if it falls on the surfaces, or when it comes into contact with people,” Lingli Zhou said. The study found that people with diabetes, or high blood pressure, and smokers, carry huge amounts of the said protein, which enhances its ability to attract the virus.

The scientists wrote in a medical paper published on the “bioRxiv” site specialized in research and scientific affairs in the United Kingdom, that “the eye is an important carrier of the virus, as infection of the cells of the surface of the eye can spread to it more than any other means.”

The scientists recommended the necessity of wearing masks that protect the eye, or wearing glasses, especially for workers in the health sector, in addition to the need to protect the eye during crowded gatherings.

Since January, many doctors have warned that the virus could spread through the eyes when the disease center was in Wuhan. At the time, doctor Wang Guangfa reported that he believed he had a SARS-like infection because he was not wearing goggles. Days before the symptoms of pneumonia appeared, Dr. Wang, a respiratory specialist at Peking University, complained of red eyes.

According to the British newspaper, “The Mirror,” health officials believe that viral pink eye, or eye inflammation, may develop in Corona patients, as statistics indicate that the number of people with eye infections has risen from about 1 per cent to about 3 per cent since the epidemic spread .
