The number of containment zones has now lowered to the 100-mark for the first time in 470 days in Delhi, witnessing fewer new Covid-19 cases and a low positivity rate. In fact, the number had come down to 99 on Thursday.

The last time when Delhi had 100 containment zones was more than a year ago on May 28, 2020. It was seen that the number of red zones has halved in the last 20 days as there were 234 such areas on August 20.

It was seen that less than four months ago, the number of containment zones stood at a staggering 57,800. Currently, two out of the 11 revenue districts have zero containment zones. Out of the 100 zones at present, the number of active zones is 75 and 25 are in the process of being scaled down

As there was an exponential growth of cases during the Second Covid-19 wave which was witnessed in April-May where the number of containment zones skyrocketed and reached the peak of 57,800 on May 18. The number fell drastically to 500 in mid-July and dipped below the 250-mark on August 20, out of which active zones were 158 and 76 were being scaled down.
Whereas, South district has the highest number of containment zones at the present with 27, compared with 29 it had 20 days ago. While West district has the second highest number of containment zones at 14, down from 22 on August 20.

These districts are followed by North West (13), New Delhi (12) and North (10). In the remaining districts, the number of containment zones is in single digits. Central and North East districts have zero containment zones.

The decline in the number of containment zones and active cases has led to higher contact tracing and surveillance. An official said with the number of red zones being very low in most districts, a stringent watch was being kept not only inside the zones, but also in the buffer areas.
