COVID-19 Relapse An Emerging Concern, Say Scientists. Explain Way To Find Out

COVID-19 Relapse: While SARS-CoV-2 re-infection is still a rare phenomenon, Indian scientists have developed an easy-to-use epidemiological definition of re-infection for establishing surveillance systems.

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 or relapse of COVID-19 by Indian scientists for establishing surveillance systems, according to a study by top medical body ICMR. But a confirmation of the re-infection will require a whole genome sequencing, it stated. While SARS-CoV-2 re-infection is still a rare phenomenon, Indian scientists have developed an easy-to-use epidemiological definition of re-infection for establishing surveillance systems. According to the study 'SARS-CoV-2 re-infection: development of an epidemiological definition from India' which has been published by Cambridge in the Epidemiology and Infection journal, 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.
