Brazil witnesses world first case of two strains of COVID 19
Today (2 Feb 64) Institute of Biotech NSTDA reports the results of the study from the medical website. medRxiv Who stated that two Brazilian men were found, aged 30, in the city Rio de Janeiro Infected with coronavirus, or SARS-CoV-Two species were seen at the same time, the first time in the world. The first species is a species that can be found widely in Brazil. P.2, also known as species B.1.1.28
It is not clear what kind of other species it is. Which in Brazil is frequently detected with both species Species UK. B.1.1.7. Or (N501Y) ,South African species B.1.351 or (501.V2) and COVID G
Brazilian virologists commented that two virus strains were found in the same person. It may cause the virus to mutate faster. Because viruses have the opportunity to exchange genetic material with each other
Initially, both patients had mild symptoms. They both had a dry cough, sore throat, headache and did not need to be hospitalized.
However, this is not too worrying. Due to the nature of the corona virus There is a chance to exchange genetic material when the virus is in the same host. But the genetic line type RNA Of the virus SARS-CoV-2 Regardless of which species are now more than 99% the same, so the genetic exchange between the two now Will get the same genetic material back Which vaccines now produced are not a problem
If it’s a very different coronavirus Coexist in a bat or a central animal like an armadillo. It would be more of a concern. Because the exchange of genetic material may acquire new strains Which seems to be a mechanism that produces new pathogens like SARS-CoV-2 that infect the entire world today
Therefore, viral infection SARS-CoV-2 in two strains of patients simultaneously is possible. Especially in regions where the virus is highly diverse. But the chance of mutating into a new virus is still difficult. But there is a possibility that a vaccine against viral resistance will be developed.
Dr. Maria Van Kirkhof, Chief Technician, Covid-19 Health Emergencies Program World Health Organization Or WHO Latest global COVID situation report That the British novel coronavirus It has now spread to 82 countries around the world. The covid virus is mutated in South Africa. Which was first detected in October last year Now the epidemic has spread to 39 countries, including the United States. The mutant COVID first discovered in Brazil has been reported in nine countries.
The COVID-19 virus actually has mutations all the time. But only the above 3 strains of COVID mutated That worries WHO and scientists This is because scientists have detected that all three strains are more contagious than the original COVID. Make the epidemic faster
It is also because scientists have found no good signs that These three mutants may reduce the efficacy of current global novel coronavirus vaccines. Existing vaccines Can still resist the mutation of COVID
