Your virus common cold seems to offer protection against that COVID-19 contagion, according to a new study published in the Journal of Infectious Diseases.
Research from the University of Glasgow Virology Research Center shows that human rhinovirus, the virus that causes the common cold, causes a innate immune response, which appears to block the proliferation of SARS-CoV-2 in respiratory cells.
More or less, this could simply mean that those who have a common cold are in some way protected from the common cold. coronavirus or that some prophylactic or suppressive treatment for COVID-19 could be developed, based on the common cold virus.
The rhinovirus “embankment” in the coronavirus
Computer simulations have shown that the interaction of the two viruses can have a wide effect and that a prevalence of rhinovirus could reduce the risk of new cases of coronavirus.
Human rhinoviruses cause the common cold and are one of the most common respiratory viruses. Previous studies have shown that interactions of rhinoviruses with other respiratory viruses can affect the type and severity of infections that people develop, but also how they are transmitted to the community.
Viruses infect a small number of specific cells in the body, and respiratory viruses generally target respiratory cells.
In the present study, the researchers initially infected human cells respiratory system with SARS-CoV-2 in the lab, which essentially represents what is actually happening. They then studied the proliferation of the coronavirus in cells, both in the presence and in the absence of a rhinovirus.
As the teacher says Pablo Brushes from the University of Glasgow “The study shows that the human rhinovirus that causes an innate immune system response to human respiratory epithelial cells can block the proliferation of the coronavirus. This practically means that the immune response can cause a mild common cold, but will offer temporary protection against the SARS-CoV-2 and this, in turn, will reduce the coronavirus transmission person-to-person and will reduce the severity of COVID-19 infection. “
Scientists’ next goal after this new finding is to see what happens at the molecular level when the two viruses interact to understand how they affect the human-to-human disease transmission process.
“We can use this valuable knowledge to our benefit and develop drugs and strategies to control COVID-19.”, explains Professor Mourtsia, remembering however that “For the time being vaccination it is the best method of protection against infection. “
