Coronavirus has mutated into at least 30 different strains new study finds
The study was carried out by
Professor Li Lanjuan and colleagues from Zhejiang University in
Hangzhou, China and published in a non-peer reviewed paper released on
website medRxiv.org on Sunday.More than 30 different mutations were detected, of which 19 were previously undiscovered.
“Sars-CoV-2 has acquired mutations capable of substantially changing its pathogenicity,” Li wrote in the paper. The team discovered that some of the mutations could lead to functional changes in the virus’ spike protein, the South China Morning Post reported. Spike protein is the protein that the coronavirus uses to attach itself to human cells.Li
's team infected cells with COVID-19 strains carrying different
mutations, of which the most aggressive strains were found to generate
as much as 270 times as much viral load as the weakest strains. The
aggressive strains also killed the human cells the fastest.The results indicated "that the true diversity of the viral strains is still largely underappreciated,” Li wrote.The
study could have future implications on the treatment of coronavirus,
as several different strains have been found throughout the world. The United States,
which has the world's worst death toll at 42,897, and 799,515 overall
cases, has been struck by different mutations. New York, which itself
had the worst death rate in the US, and the eastern coast show a strain
of coronavirus similar to that found in Europe, whereas the western US
has shown similarities with strains found in China.Coronavirus
has so far been treated in hospitals worldwide as one disease and
patients receive the same treatment regardless of the strain. It has
been suggested by the team at Zhejiang University that defining
mutations in different regions may change the way we approach combating
the virus. “Drug and vaccine development,
while urgent, need to take the impact of these accumulating mutations
into account to avoid potential pitfalls,” the scientists said.
