The Covid-19 pandemic is changing but it is not over, head of the World Health Organization said on Wednesday, cautioning that the cases are on the rise in 110 countries and are being driven mainly by two fast-spreading Omicron sub-variants. The Centers for Disease Control and Prevention said this week that the fast-spreading Omicron sub-variants BA.4 and BA.5 together are estimated to make up half of the coronavirus cases in the United States. As of June 25, BA.5 made up 36.6 per cent of the total coronavirus cases in the US while BA.4 accounted for 15.7 per cent, together accounting for about 52 per cent of new cases in the US.
With the rise in Covid-19 cases in India, union Health Secretary Rajesh Bhushan wrote to all states asking them to integrate Covid-19 surveillance into their routine surveillance activities and follow the revised guidelines for surveillance in three areas — incoming international travellers, sentinel sites such as hospital and laboratories, and within the community, along with wastewater sample collection. The states have been asked to screen 2% of the international passengers coming to India at random and send all positive samples for genome sequencing.
