Some viruses compete in trying to infect human cells.
According to scientists at the University of Glasgow, the flu-causing rhinovirus has been found to defeat the coronavirus.
The benefits may be short-lived.
How is coronavirus defeated?
Think of your nose, throat, and lung cells as rows of houses. Once a virus enters, it either opens the door or closes the door to allow other viruses to enter.
The influenza virus that causes the flu is very selfish and often infects alone. Other viruses, such as adenoviruses, co-infect others.
There has been a lot of speculation about how the coronavirus called Sars-CoV-2 interacts with other viruses.
But one year of physical distance rules has slowed down the spread of all kinds of viruses. This has made it more difficult for scientists to study the interaction of viruses.
A research team from the Glasgow-based Center for Virus Research conducted a study using a replica of a human trachea. Similar cells were used for that purpose. The cells were infected with SARS-COV-2 virus and rhinovirus.
When infected with Rhinovirus and SARS-COV-2 at the same time, only the flu-infected rhinovirus could infect the cell. Twenty-four hours before the rhinovirus entered the cell, the coronavirus did not have a chance to affect it.
And even if the coronavirus has been infected for 24 hours, the rhinovirus will expel it from the cell.
“SARS-COV-2 cannot spread, rhinoviruses prevent it,” said Dr. Pablo Murcia told BBC News.
“This is very encouraging because an excess of rhinovirus can prevent SARS-Cove-2 infection,” he said.
Such effects have been seen before. Following the outbreak of the rhinovirus in 2009, the swine flu epidemic slowed in parts of Europe.
Further use and testing have shown that rhinovirus-infected cells have increased resistance to disease, which in turn has hampered their ability to increase the number of coronaviruses.
When scientists stopped such an immune response, they found that the level of the covidian virus increased as in the absence of rhinovirus.
But once the flu is cured and the immune response to the rhinovirus weakens, there is a possibility of covid.
“Vaccines, hygiene measures and interactions between viruses can greatly reduce SARS-COV-2. Murcia said.
