India is seriously examining every emerging aspect of the novel coronavirus, which has affected nearly 60 lakh people in the country so far, Union Health Minister Dr Harsh Vardhan said today, while stressing on the cases of re-infection. While replying to a question by NDTV, the Health Minister explained about the cases of re-infection across the world, which have emerged as a serious worry amid the pandemic. "There are several cases of re-infection from across the world, not just in India. At the moment, the subject is still under serious investigation and doesn't appear to be a serious issue. However, in the health ministry, each and every aspect of COVID-19 that is emerging is being studied," Dr Harsh Vardhan said.
