Suara.com – The new variant of the corona virus has actually spread to several countries, one of which is India. In the past two months India has recorded a total of 192 cases of Covid-19 from the new variant, four cases from the South African variant, one Brazilian variant, and the rest from the British variant.
According to the Director General of the ICMR, Prof. Balram Bhargava, on Tuesday (15/2/2021), the South African variant was found in four people who returned from the African country in January. One person from Angola, one from Tanzania and two from South Africa.
Meanwhile the Brazilian variant (P.1) was detected in someone who had just returned from South America earlier this month.
These variants have been isolated and cultured at the National Institute of Virology (NIV), Pune, for use in trials assessing vaccine efficacy.
Why Are Scientists Worried About the South African Variant?
According to The Health Site, this variant of the corona virus was first detected in Nelson Mandela Bay, South Africa, in early October 2020 and within weeks became the dominant strain in the country.
Bhargava said this variant has now spread to 44 countries. South African researchers have found this variant has 8 different mutations in the spike protein.
This variant carries the N501Y mutation, which appears to make the virus more contagious and another mutation, E484K, allows it to escape the immune system and reduce the effects of the Covid-19 vaccine.
Last month Novavax announced that its vaccine was nearly 85% effective against the British variant, but only demonstrated 50% effectiveness in preventing infection with the South African variant.
However, there is no evidence that variant B.1.351 causes more serious disease than other variants.
