Corona infection in Tamil Nadu has been declining since last October. On average, more than 600 people a day are affected in areas under the Metropolitan Corporation of Chennai.
In this case, if more than 5 people are infected in the same area or on the same street, all those areas will be declared as control areas. In this situation, the number of survivors has been increasing over the last few days in the metropolitan areas of Chennai.
The control area is also reduced. In that sense, the Manjapakkam area is currently the only controlled area in the Metropolitan Corporation of Chennai.
