The new lineage called B.1.618 is distinct from the B.1.617, also known as the 'double mutant' virus that contains two mutations, E484Q and L245R, and is believed to be behind the powerful second COVID-19 wave sweeping through India.
A third wave of COVID-19 -- if it occurs -- is unlikely to be as severe as the second wave given the extent of spread of coronavirus infections that has already taken place in the country, according to a study.
Three researchers from the Wuhan Institute of Virology sought hospital care in November 2019, weeks before Beijing disclosed the COVID-19 pandemic, a United States media report said, citing a previously undisclosed American intelligence document that could add weight to growing calls for a full scale probe of whether the coronavirus may have escaped from China's top bio lab.

The new test it will enable rapid testing amongst more people easily.
The Centre is conducting a study to assess the presence of SARS-CoV-2, or novel coronavirus, in the Ganga as corpses were found dumped in the river during the second Covid wave, and were fished out from districts in Uttar Pradesh and Bihar, officials said.
