According to American Scientists, the attack of the virus of seasonal Flu and the coronavirus have great similarities and the immune system against the virus of seasonal flu can be helpful in fighting Covid-19.
The medical history tells us that the people who fall victim to seasonal flu before the spread of flu, usually are saved from it.
There appears to be a viral sweet spot at the beginning of COVID-19, during which the virus replicates exponentially before it triggers a strong defense response.
The scientists are of the view the common respiratory virus jump-starts the activity of interferon-stimulated genes, early-response molecules in the immune system which may prevent replication of the SARS-CoV virus within airway tissues infected with the cold.
Triggering these defense systems early in course of coronavirus infections, hold promise to stop the infection. Depending upon the former research which showed that the seasonal flu virus may protect against influenza, the scientist decided to go ahead to see whether rhinoviruses may have the same impact against Covid-19.
The team of scientists infected lab-grown human airway tissue with SARS-CoV-2 and then they came to know that during the first three days, a load of the virus on tissue became double about every six hours. But the replication of the coronavirus had completely stopped in tissues which were exposed to rhinovirus.
If the antiviral defense system was blocked, the SARS-CoV-2 could replicate in airway tissue previously exposed to rhinovirus. The scientists also came to know that nasal swab samples from patients diagnosed close to the start of infection. The rapid growth of SARS-CoV-2 was found in the first few days of the disease flowed by the activation of the body’s defense.
The research may help in finding why at the times when colds are common, rates of infections with other viruses like influenza get slow. The scientists are of the opinion’ “There are hidden interactions between viruses that we do not quite understand and these findings are the piece of the puzzle, we are just now looking at.”
