The Dharavi slum in Mumbai registered no new coronavirus cases on Friday for the first time since the detection of the first case in the area in April, PTI reported.

Asia’s largest slum has so far recorded 3,788 infections. The area’s active cases have just been reduced to 12 as 3,464 people have recovered.

Over 6 lakh people live in the Dharavi slum. Health experts were worried that the coronavirus would spread uncontrollably in the area because of little possibility of physical distancing and poor hygienic conditions.

The officials have been able to control the spread of the coronavirus in Dharavi by carrying out house-to-house screening and extensive testing, according to India Today.

In July, the World Health Organization had also praised the successful containment efforts in Dharavi. WHO Director-General Tedros Adhanom Ghebreyesus said the area showed that “a strong focus on community engagement and the basics of testing, tracing, isolating and treating” were important for breaking the chain of transmission of the virus.
