Maharashtra is "in the beginning of a second wave of Covid", the centre has said in a letter to the Uddhav Thackeray-led government, urging the state to focus on containment strategies. The letter, based on the assessment of a central team, notes the lack of Covid-appropriate behavior and "tracking and testing of cases". Union Health Secretary Rajesh Bhushan has written to Maharashtra Chief Secretary after the central team's visit last week.
