As the world continues to fight the outbreak of the Corona pandemic, science is trying to uncover the hidden secret of this virus, which has killed more than 280,000 people worldwide.
In the latest of these studies, scientists have discovered a surprising new way that the Coronavirus can transmit its infection, through infection, through tear fluid. The results of this study were published on the MedRxiv Medical Specialist portal.
Specialists from the Johns Hopkins University School of Medicine discovered that the ACE-2 protein found in cells on the ocular surface is not only the entry point for virus infection, but the enzyme TMPRSS2 also helps the virus to enter the body, after the virus attaches itself to the ACE-2 protein.
Scientists have also noted that the presence of ACE-2 and TMPRSS2 in the same cell is not only a sufficient condition for the virus to reproduce effectively, but it also transmits infections and spreads the virus efficiently and frequently.
Specialized experts have confirmed that cells on the ocular surface are not only susceptible to CoV-2 SARS infection, but can also act as a “reservoir” of the virus.
For this, the scientists concluded that “the infection of the cells of the surface of the eye can lead to the fact that the eye becomes a carrier of the virus, and the tear fluid that contains the virus particles becomes an important mechanism for transmission to other people. “
Sneezing, coughing, and breathing.
The US Centers for Disease Control and Prevention. USA And other health agencies have confirmed that the primary route of transmission for the crown is through respiratory droplets, up to 1 millimeter wide, that are produced when a person coughs or sneezes.
But recent research has confirmed that the emerging coronavirus is transmitted not only through sneezing and coughing, but also through speech or even breathing.
“While current accurate research on the virus is limited, the results of available studies are consistent with transmission through transformation of the virus,” said Dr. Harvey Weinberg, a letter written by the Chairman of the Diseases Committee. Emerging Infectious Diseases and Health Threats for the 21st Century at the United States National Academy of Sciences, NAS. In small particles that can fly through normal breathing. “
