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.More Related News
