Coronavirus May Have Mutated To Become More Contagious, Study Finds

Dozens of studies of interferon treatment are now recruiting COVID-19 patients.New York, Sep 25 (IANS) A standard test that assesses blood cells can identify which patients admitted to hospital with Covid-19 could face a high risk of becoming critical and die, say researchers. The spike is helpful for the virus in infecting the host cells.A death due to Covid-19 may not be attributed to another disease, such as cancer, and should be counted independently of preexisting conditions that are suspected of triggering a severe course of Covid-19. They may also provide the first molecular explanation for why more men than women die from the disease.When two brothers fell critically ill with COVID-19 around the same time in March, their doctors were baffled. “And at least in theory, such interferon problems could be treated with existing medications and interventions”.The researchers said that the study is meant to help scientists understand the composition and trajectory of future infection waves.The way SARS-CoV-2 affects people differently has been puzzling.”It looks like this virus has one big trick”, stated Shane Crotty, a professor within the Center for Infectious Disease and Vaccine Research on the La Jolla Institute for Immunology in California.Being male, aged, and having underlying medical circumstances can all elevate sufferers’ danger of life-threatening Covid-19. Moreover, compared to the first wave of infections, patients on average had higher levels of the virus in their system during this second wave. More than 3.5 per cent completely lacked a functioning gene.Genetic evaluation of Covid-19 sufferers printed in the identical journal revealed two dozen gene mutations that had been “silent” till sufferers have been contaminated by SARS-CoV-2.The Herolds believe these proteins are part of an innate immune response that the body seems to rely on less as it ages. They are known to play an important role in immediately heightening the cells’ defenses in response to several viruses. Most mutations have no impact, but this process sometimes changes the virus’ behavior or makeup, and if that change helps the virus spread, a mutated version of the virus can eventually dominate through natural selection.In other people with severe COVID-19, the immune system turns against interferons themselves to cause severe disease, Casanova and his team found in the second study. So next, the team checked for the possibility of a similar scenario.As the novel Coronavirus has affected over 31 million people and claimed more than 976,000 lives globally, the healthcare providers are now facing challenge to identify those COVID-19 patients who are at the maximum risk of severe illness or death.The finding needs further validation in broader cohorts of patients, but if confirmed, this simple laboratory test may be a useful way to detect those COVID-19 patients most in need of clinical care.
