Normally, an area is marked a containment zone where three or more COVID-19 cases are detected. But it is a dynamic exercise, conducted by district authorities on a need-based manner, they said.
The Delhi Epidemic Disease COVID-19 Regulation, 2020, authorises district magistrates to seal off a geographical area, banning entry and exit of the population from the containment zone and to take any measures directed by the health department to prevent the spread of the disease.
Delhi has been witnessing a spike in coronavirus cases since June 14 when the cases breached the 1000-mark.
Delhi logged 1,118 new cases on June 14, with a positivity rate of 6.50 per cent and two fatalities.
Since then, the national capital has been logging more than 1,000 cases everyday barring Wednesday when it logged 928 single-day infections.
Delhi recorded 1,447 new Covid cases and one more death on Friday, while the positivity rate dropped to 5.98 per cent, according to data shared by the health department here.
According to officials, the spike in coronavirus cases is due to the lax attitude of the people in following Covid-appropriate behaviour. The strategy focuses on containing the spread of infection.
“Currently, even if there are two cases in a family or in adjacent households, they are designated as a containment zone. The intention is to contain the spread of infection as Omicron is highly transmissible,” said an official.
