Punjab chief minister Amarinder Singh Friday announced the extension of lockdown in the state till 1 May, a day after Odisha extended it to 30 April.

Singh said that most of the 27 positive cases reported in his state on Thursday — the maximum daily increase for the state — were those of secondary transmission and expressed apprehension that the state may be entering the community transmission stage of the outbreak.

In Tamil Nadu, an expert committee recommended to Chief Minister K Palaniswami that the lockdown be extended by two weeks beyond 14 April considering the rise in number of cases.

A review meeting was also held by the Prime Minister's Office during the day on various efforts to check the coronavirus spread, which also discussed ramping up of production of personal protective equipments (PPEs) among other issues.

The Home Ministry, separately, has sought views of state governments on the 21-day lockdown, scheduled to end on 14 April, including whether more categories of people and services need to be exempted, officials said on Friday.
