Top Virologist Claims Covid 3rd Wave Has Ended, No 4th Wave Will In India\r\nObserving that the third wave of COVID-19 has ended in India, esteemed virologist Dr. T Jacob John said he is \u201cfairly confident\u201d that there won\u2019t be a fourth wave in the country unless an unexpected variant that behaves in a different way comes up.\r\nIndia recorded 3,993 new coronavirus infections, which is the lowest in 662 days, on Tuesday. The third wave of COVID-19 has plateaued in India and the number of cases have started falling after 21st January when 3,47,254 total infections were reported.\r\nJohn who is the former director of the Indian Council for Medical Research\u2019s Centre of Advanced Research in Virology, said it can be confidently said that the third wave of the pandemic has ended and the country has entered an endemic phase again.\r\n\r\nIndia has entered the endemic stage\r\n\u201cI say (entered the endemic stage) since my own definition of an endemic state is \u2018low and steady daily numbers, with only minor fluctuations, if any, for at least four weeks\u2019. My personal expectation, hence opinion, is that we will be in the endemic phase for more than four weeks. All states in India show the same trend, giving me this confidence,\u201d he said.\r\n\r\n\r\n\r\n\r\n\r\n\r\nThe \u2018endemic stage\u2019 is when a population learns to live alongside a virus. It differs from the \u2018epidemic stage\u2019 when the virus overwhelms a population. Various virologists were also of the opinion that there would be no third wave. When John was asked about this, he explained that the third wave was driven by Omicron and no one had predicted something like this to emerge. The assumption that \u2018no third wave would come\u2019 was based on the variants present at that time.\r\n\r\nNo fourth wave unless\u2026\u00a0\r\nUnless an unexpected variant that behaves in a different way from alpha, beta, gamma or if Omicron, there would be no fourth wave according to John. And with all the epidemiological and virus variant information available in India currently and also keeping in mind the global trend, John is confident that a fourth wave will not occur.\u00a0\r\n\r\nPast trends\r\nElaborating on the matter, the virologist stated all previous pandemics of respiratory-transmitted diseases have been due to influenza and every influenza pandemic in the past ended after two or three waves, and remained in an endemic phase, with small fluctuations of seasonal upsurges which always settled back to low numbers.
