The time that the virus takes to kill the lungs has been decreasing with consecutive waves. In the first wave, it killed the lungs in 10 days, which reduced to 5-7 days in the second wave. This time could even decrease to 2-3 days in the third wave of the pandemic. The Andhra Pradesh variant is working similarly. This COVID-19 variant kills a person’s lungs within 2-3 days and is also 15 times more contagious than any other variant of the virus.
