Indian scientists have identified 10 subtypes of coronavirus, of which one was dominant. This is with reference to the study reports India Times.
Scientific work was prepared by Nidhanam by Biswas (Nidhan Biswas) and Madjumder Partha (Partha Majumder) from the National Institute of biomedical genomics (India). Scientists have discovered 10 different subtypes of SARS-CoV-2, which is about four months mutated from the parent virus O Type O experts have called the main type of coronavirus circulated in the Chinese city of Wuhan.
From all 10 subtypes of type A2A was the strongest. The virus effectively and in large quantities into the lungs, which contributed to the momentary contamination of the patient and spread of infection. As a result, according to scientists, COVID-19 quickly spread in almost all continents of the planet.
The researchers were able to identify the dominant virus subtype based on the analysis of shared libraries GISAID. It contained RNA sequences from 3600 coronaviruses collected in 55 countries in the period from December 2019 to April 2020.
Scientists noticed that A2A viral particles penetrated into the throat of the patient, where they enter the lungs. Due to the mutation of the virus changed a key component of protein necessary for connection with the cells of the lungs, which allowed him to quickly settle in the host organism. A2A it was found at 47.5 percent of the samples obtained from cases in India of people, the majority of those infected had not traveled outside of the country.
Reporters noted that the sample of scientists was extremely small, as it was based on only 35 samples. However, the study one way or another can help to understand the way of the spread of coronavirus, the dependence of the contamination from the ethnic composition of cases and to develop a vaccine against COVID-19.
