India has received a total of 3 532 Sars-CoV-2 concerns in 27 provinces, the government announced Wednesday, adding that a third wave of Covid-19 was inevitable given the current increase in infections.
Researchers have found that the prevalence of the UK (B.1.1.7) variant, which is known to be 50% higher, is declining in India, and the double density (B.188.8.131.52) is increasing, say senior scientists.
Vijay Raghavan, senior science adviser to the Indian government said that the third stage is inevitable, given the high levels of the virus, but it is not clear when this phase 3 will occur. Hopefully, more and more, but they have to be prepared for new waves. Pre-existing infections and vaccines will create a constant pressure on the virus for new types of mutations that try to escape, so they must be prepared, scientifically, for that.
That disturbing variation of the existing variants in which there is evidence of increased transmission, more serious diseases etc.
He also said that the scientists are also now also mapping the laboratory for all the possible changes in the virus and they are also seeing how these changes can affect immune system immunization and also the immunization.
There are many factors that have contributed to the second wave and the difference is one of the factors, says Vijay Raghavan.
The first wave hit September last year and dropped for two reasons, he said. He also said that as the infection spread, so did the immune system. The combination of human immunity and precautionary measures has halted the spread of the first wave.
But as the precautionary measures decreased, new opportunities for infection and the immune system in humans were often insufficient to stop the spread of infection. Many people become infected and reach new heights. A second such wave was expected. However, many parameters can change and not reach the second wave, much larger than the first.
He said that but the second wave so big and the violence they see has never been predicted.
A consortium of 10 advanced laboratories produces a successive sample of samples nationwide since December 2020, finding that the UK (B.1.1.7) variant of Sars-Cov-2 that dominated the past, still declines in the country, and doubles variables B.1.617) which is gradually becoming more and more apparent.
Dr SK Singh, director, National Center for Disease Control, Delhi said that they have seen the B.1.1.7 genealogy that was prevalent in the first period, especially in the provinces of Maharashtra and later Delhi, declining equally in the last month and a half. To this day, their lineage of B.184.108.40.206 which originally focused on the beginning of Maharashtra, is now found in many other provinces. And in some provinces, they have established its integration with current expansion. However, its epidemiological and clinical integration needs to be established by now.
Three and four provinces showed the highest load, including Maharashtra, Punjab, Delhi, Andhra Pradesh and Telangana, Dr Singh said in a statement.
Experts also say that in addition to high referral, clinical interactions were important. Dr. Gagandeep Kang, professor at Christian Medical College, Vellore. Singh added saying that the INSACOG data [Indian Sars-Cov-2 Genome Sequicing Consortium] only shows that the exception, especially B.1.617 may have some advantage over the spread, but that related to phase 3 remains to be seen. He also said that at least 1.3 million changes have been announced worldwide so far at Sars-cov-2, and not all changes are worrying.
