New Delhi, May 4 (IANS): With three more zones de-contained on Monday, the total number of containment zones in the city stood at 90.

According to the Delhi government, the areas de-contained on Monday were in the West district -- in and around area of -- 11/3, 2nd Floor Ashok Nagar (sealed on April 8);A 36/4, East Patel Nagar (sealed on April 13); G-174, Capital Greens, DLF, Motinagar (sealed on April 8).

"So far, 10 areas have been de-contained and now the active containment zones in the city are 90," an official statement said.

After an area is announced as a containment zone by the district administration, the Delhi government starts 'Operation SHIELD' in the area to contain the spread of the infection.

The government used Operation SHIELD -- Sealing, Home Quarantine, Isolation and Tracking, Essential Supply, Local Sanitisation and Door-To-Door Checking -- to control the spread of the virus.

While the 10 areas are no more a containment zone, however, strict compliance of the lockdown has to be followed in the areas.

The SHO concerned and the survey teams, as constituted by the District Administrative, have to keep a strict vigil in the de-contained areas to make sure that there should be minimum movement of people as per directions issued by the government with regard to the lockdown.

The SDM will need to keep strict vigil in the area for the next 14 days from the date of de-containment.

Social distancing and masks are compulsory in the area even for the vendors, hawkers.

On Sunday, Delhi announced several relaxations from Monday for the city, except the containment zones.
