ICMR: 3 cases of coronavirus re-infection in India, 24 globally

New Delhi: The Indian Council of Medical Research (ICMR) on Tuesday said at least three cases of Covid-19 re-infection have been reported from across the country so far, whereas 24 such cases have been found globally.

The three cases of re-infection brought to the notice of ICMR include two in Mumbai and one in Ahmedabad, ICMR director general Balram Bhargava said. Meanwhile, the ‘Lancet Infectious Diseases’ journal on Tuesday said a patient with confirmed re-infection with novel coronavirus in the US showed more severe symptoms in the second infection than in the first.

This assumes significance as re-infection cases indicate that there is no assurance that a person infected with coronavirus once develops immunity for future. Secondly, while many experts have been hoping that the re-infection is mild, the Lancet report shows that this may not always be the case.

“The criteria to identify a re-infection case is somewhere between 90 and 100 days. WHO has not yet decided the number of days. However, we're taking a cut-off of about 100 days,” Bhargava said.

Re-infection cases are those where people contract the virus for the second time after being cured. The first instance of coronavirus re-infection was recorded in Hong Kong when a 33-year-old man who was initially infected in March and had recovered got re-infected more than four months later after a trip abroad.
