In the early days of the coronavirus epidemic, it was said that the virus could be transmitted from our eyes. If it is a new research, Covid-19 SARS-CoV-2 virus in our eyes from corneal tissue examined whether it could enter the body.
As the epidemic is almost in its first year, we are still learning new information about how Covid-19 spreads. We already know that the virus is mainly transmitted through respiratory droplets or small particles emitted when an infected person coughs, sneezes, speaks or exhales. But in the early days of the epidemic, governments around the world believed that much of the transmission of disease was caused by touching your own face after touching an infected surface.
U.S. Centers for Disease Control and Prevention (CDC)
droplets as specified by “ can drop onto surfaces and objects and be moved by touch. A person can catch Covid-19 by touching their own mouth, nose or eyes after touching a surface or object with the virus on it. “While this recommendation is still one of the accepted routes of transmission, the CDC now states that it is not the main route of transmission of the virus.
Some experts suggest that the virus can enter the body through the mouth and nasal passages, as well as the eyes. Patients who are infected with the virus often also have eye fever, and it is possible that this is due to Covid-19 or due to another mechanism. St. Researchers from the University of Washington School of Medicine in St.Louis have also studied exactly this issue.
Publishing their research in the journal Cell Reports, the team aimed to make sure that the eyes would be an entry point for the SARS-CoV-2 virus, since it had been previously shown that the Zika virus was in tears. They tested human (donor sourced) and mouse corneas for Coronavirus, Zika, and herpes and measured the virus’s ability to multiply.
Although Zika and herpes can reproduce in the cornea, according to research, SARS-CoV-2 cannot reproduce. Senior writer and ophthalmologist Rajendra S. Apte
Although this may be said to be a good finding, the team does not forget to make an important warning. Even though the coronavirus cannot reproduce in the cornea, the behavior of other tissues such as the tear ducts and conjunctiva surrounding the cornea has not yet been studied. Besides that, the lead author Professor Jonathan J. Miner
As points out, the team’s findings do not prove that all corneas are durable either, and only by chance it is possible that all donor corneas they tested are resistant.
