Lateral flow tests, comprising rapid-antigen and home-antigen tests, can diagnose COVID-19 between the third and the eighth day after exposure to the virus, while the RT-PCR test can detect the virus for up to 20 days, Indian Council of Medical Research (ICMR) Director-General Dr Balram Bhargava said on Wednesday, 12 January.
He added that on the first day of the virus entering one's body, all tests would show a negative result.
Speaking on the infectious period of the RT-PCR test, he explained that the results would continue to detect the infection after the eighth day since certain RNA particles, which are non-infective, would resume shedding and continue to cause test results to be positive, news agency PTI reported.
The central agency, reiterating the guidelines, stressed the importance of a 7-day home quarantine period for all contacts of any COVID-positive patient and added that they should continue to wear a mask.
Head of the COVID Task Force in the country, Dr VK Paul, underlined that the Omicron variant of COVID-19 was not a 'common cold', dispelling a misconception that has come to the fore.
Dr Paul stated:
"It's a fact that vaccines are helpful to an extent. Vaccination is a critical pillar of our COVID response," he added.
This statement came a day after a top epidemiologist at ICMR, Jayaprakash Muliyil, underplayed the virus in order to tackle the pandemic with a fresh lens.
Muliyil had said, "The consequence of a viral infection now is just like a cold. We have to recognise that we have been chasing a particular kind of objective so far."
