ICMR study provides a new definition for SARS-CoV-2 re-infection
The Hindu
An epidemiological working definition will be more pragmatic and helpful to assess the magnitude of re-infection in most population and resource constrained settings.
Two positive tests at an interval of at least 102 days with one interim negative test have been defined as SARS-CoV-2 re-infection for establishing surveillance systems, . But a confirmation of the re-infection will require a whole genome sequencing, it stated. According to the study published in the journal Epidemiology and Infection, an investigation was conducted with the objective to develop an epidemiological case definition of possible SARS CoV-2 re-infection and assess its magnitude in India. SARS-CoV-2 re-infection is an emerging concern and there is a need to define it, the scientists highlighted. Therefore, working epidemiological case definition for re-infection was developed and its magnitude was explored via archive-based, telephonic survey.

How do you create a Christmas tree with crochet? Take notes from crochet artist Sheena Pereira, who co-founded Goa-based Crochet Collective with crocheter Sharmila Majumdar in 2025. Their artwork takes centre stage at the Where We Gather exhibit, which is part of Festivals of Goa, an ongoing exhibition hosted by the Museum of Goa. The collective’s multi-hued, 18-foot crochet Christmas tree has been put together by 25 women from across the State. “I’ve always thought of doing an installation with crochet. So, we thought of doing something throughout the year that would culminate at the year end; something that would resonate with Christmas message — peace, hope, joy, love,” explains Sheena.
