What is Covid-19 reinfection | India News

NEW DELHI: Two healthcare workers from a Noida hospital could be India’s first genetically proven cases of Covid reinfection, according to the preprint of a research paper submitted by the prestigious Institute of Genomics and Integrative Biology, a Council of Scientific and Industrial Research laboratory located in Delhi.
The IGIB team has also established reinfection in four health workers from Mumbai —three from Nair Hospital and one from Hinduja. Here is all you want to know about Covid-19 reinfection.

  1. What is Covid-19 reinfection?

    When a patient tests positive for SARS-CoV2 less than three months after onset of symptoms, the test could represent a new infection. Scientists have to use genetic sequencing and match entire or pieces of the viral genetic material gathered from the first and second swab samples of the patient. There are subtle differences in the genetic material of different strains of SARS-CoV2. If differences show up during sequencing, it is clearly a case of reinfection.
