"Coronavirus Rapidly Mutating," Says AIIMS Delhi Director

All India Institute Of Medical Sciences (AIIMS) Delhi Director Dr Randeep Guleria said that the coronavirus is rapidly mutating and clarified that an RT-PCR false negative is possible as the Covid test is only 80 per cent sensitive. Currently, the RT-PCR can pick up mutant strains, if the test is done properly. However, Dr Guleria said if a patient has symptoms and tests negative, they should get a re-test in 24 hours and get blood tests and CT scan done to look for other markers. Those symptomatic but awaiting reports should start treatment, he said.
