India's overall COVID-19 cases remain low, though there has been an uptick in cases in the last week in several cities. Delhi, for example, is reporting rising COVID-19 cases among children in schools, which is a worrying sign. India's top biomedical scientist Dr Gagandeep Kang said it is not known whether the XE variant is driving the rise in cases. "We don't necessarily know that all of the case that are being reported are of the XE variant unless we sequence them all," Dr Kang told NDTV today. "...It is only when we have all the pieces of the picture we can interpret data. People's data alone isn't sufficient," she said.
