IN The virus that causes the common cold can be an effective weapon against COVID-19 by expelling it from our cells, say scientists quoted by the BBC.
Some viruses are known to compete to be the ones causing the infection. And researchers from the University of Glasgow say that the rhinovirus, which causes colds, is better in this regard than the coronavirus that currently plagues humanity.
The benefits may be short-lived, but the rhinovirus is so widespread that
According to Scientists, It May Still Help Suppress COVID-19.
Think of the cells in your nose, throat, and lungs as your home. Once the virus enters, you can keep the door open to release other viruses, or you can close the door and keep this house / cage to yourself.
Influenza is one of the most selfish viruses and almost always infects itself. Others, like adenoviruses, appear to be more likely to share a house / cell.
There is a lot of speculation on this.
How the virus that causes COVID-19, known as Sars-CoV-2, would fit into the mysterious world of “virus interactions”.
The challenge for scientists is that a year of social distancing has slowed the spread of all viruses and made research difficult.
The team from the Glasgow Virus Research Center used a replica of the mucosa of our airways made from the same types of cells and infected it with Sars-CoV-2 and rhinovirus, one of the most common infections in humans and the cause from the common cold.
If rhinovirus and Sars-CoV-2 were released simultaneously, only rhinovirus was successful. If the rhinovirus had a 24-hour onset, then Sars-CoV-2 was able to enter the cell. And even when Sars-CoV-2 had a 24-hour lead, the rhinovirus displaced it.
Dr. Pablo Murcia said: “It is very exciting because
if you have a high prevalence of rhinovirus, this can stop new Sars-CoV-2 infections. “.
Similar effects have been seen before. A major rhinovirus outbreak may have slowed the 2009 swine flu pandemic in parts of Europe.
Other experiments showed that the rhinovirus elicited an immune response in infected cells, blocking the ability of Sars-CoV-2 to make copies of itself. When the scientists blocked the immune response, the levels of the COVID-19 virus were the same, as if the rhinovirus was not there.
However, COVID-19 may re-cause an infection after the cold has passed.
and the immune response subsided. Dr. Murcia said: “Vaccination, plus hygiene measures, plus interactions between viruses can significantly reduce the incidence of Sars-CoV-2, but the maximum effect will come from vaccination.”
Professor Lawrence Young of the Warwick School of Medicine said that human rhinovirus, the most common cause of the common cold, was “highly contagious.” He added that the study suggested “that this common infection may affect the severity of COVID-19 and affect the spread of SarsCoV2, especially during the fall and winter months when seasonal colds are more common.”
The results of the study are published in the Journal of Infectious Diseases.
