Participants in weddings should be restricted to 100 while only 50 persons would be allowed in death-related events, he said.
Urging people to get vaccinated, the chief minister also stressed on other covid-appropriate behaviour such as wearing face-mask.
All employees in commercial establishments should have been vaccinated against Covid-19. Further, action will be taken if mask wearing is not followed by establishments and customers.
As part of virus containment measures, Test-Track-Treat-Vaccination-Covid-19 Appropriate Behaviour will be strictly implemented, Stalin said.
Further, only essential services should be allowed in containment zones while door-to-door survey by committees in such areas will also be undertaken to prevent the spread of the contagion, he said.
Those violating pandemic containment measures will be fined, the CM warned.
He appealed to people to refrain from crowding during the coming festive season and stressed on social distancing and wearing of mask.
