The Yadadri Bhongir district, which has been a Green Zone district ever since the coronavirus outbreak hit the state, has now shocked everybody by registering four positive cases of the virus.
Three residents of Pallerla village of Atmakoor mandal, and a resident of Jangaon village of Samsthan Narayanpur mandal, have tested positive for the virus.
All these four are migrant workers who returned from Mumbai on May 5.
Following this, the officials shifted six more residents of Pallerla and four from Janagaon to the Bibinagar-based NIMS quarantine centre.
They have also set up seven check posts across the district.
