New strain could re-infect recovered persons: DAK

Doctors Association Kashmir (DAK) Monday said that the people who had recovered from COVID19 infection could be re-infected with the new mutated strain.

“Those who have got COVID19 could get sick again with the new variant,” DAK President and influenza-expert DrNisar-ul-Hassan said in a statement issued here.

“A new mutated COVID strain has surfaced in United Kingdom and is spreading to other countries,” he said. “The new variant has multiple mutations in the spike protein of the virus and the most troubling is deletion mutation which makes it spread more easily.”

Quoting a new study published in the preprint server bioRxiv, Dr Hassan said in the statement that antibodies elicited by natural COVID19 infection may not be able to neutralise emerging strains that display deletion mutations in their genetic sequence.

“Researchers from South Korea found that a young woman infected with one strain of COVID19 was, just weeks after recovering, re-infected with a different strain of the virus,” he said. “The findings indicate that the patient’s immune response to the first strain did not protect her from the second strain and highlights how mutations could make controlling COVID19 more difficult than first thought.”

Dr Hassan said the mutation in the new variant had resulted in an altered protein product which could evade the immune response elicited by earlier strain of the same virus.

“The new strain could lead to resurgence of COVID19 cases that could reignite the pandemic,” he said. “The mutated variant is the dominant strain in UK and is responsible for more than 60 percent of COVID19 cases.”

Dr Hassan said: “While we struggle to come to grips with the news of new strain of coronavirus being detected in UK, another variant of the virus, potentially more infectious has emerged in South Africa. Kashmir being the favorite tourist destination, the mutants can come to us anytime. We have to be prepared and alert – we need to gear up our hospitals to prevent an outbreak.”
