New study in China found that new coronavirus mutated in at least 30 different variations, results show that medical officials have grossly underestimated the overall ability of the virus to mutate, concluding that different strains have affected different parts of the world. , leading to potential difficulties in finding a comprehensive remedy. The study was carried out by Professor Li Lanjuan and colleagues from Zhejiang University in Hangzhou, China and published Sunday in an unpublished article published on the medRxiv.org website. Li’s team analyzed the strains of 11 randomly selected coronavirus patients in Hangzhou, where there were 1,264 cases reported, and tested the effectiveness with which they could infect and kill the cells. Over 30 different mutations have been detected, 19 of which have not been discovered before. “Sars-CoV-2 has acquired mutations capable of substantially modifying its pathogenicity,” Li wrote in the newspaper. The team discovered that some of the mutations could cause functional changes in the virus’s advanced protein, the South China Morning Post reported. The protein Spike is the protein that the coronavirus uses to bind to human cells. Li’s team has infected cells with COVID-19 strains carrying different mutations, the most aggressive strains of which have been shown to generate up to 270 times as much viral load as the weakest strains. The aggressive strains also killed human cells most quickly. The results indicated “that the true diversity of viral strains is still largely underestimated,” writes Li. The study could have future implications for the treatment of coronavirus, since several different strains were from the United States, which have the greatest number of deaths in the world with 42,897, and 799,515 cases in total, were struck by various mutations. New York, which itself had the worst death rate in the United States, and the east coast show a strain of coronavirus similar to that found in Europe, while the western United States has shown similarities with strains found in China. Coronavirus has so far been treated in hospitals around the world as one disease, and patients receive the same treatment regardless of strain. suggested by the Zhejiang University team that defining mutations in different regions could change the way we approach the fight against the virus. While it is urgent, the impact of these accumulated mutations must be taken into account to avoid potential pitfalls, “said the scientists.
