The district administration and police on Sunday imposed curfew in DS Colony and Ajanta Para of Dhanbad, less than 2km from the Dhanbad district headquarters, and restricted the movement of people and vehicles in the area after a 35-year-old railway trackman, a resident of the colony, was detected Covid-19 positive on Saturday night.

The administration also declared the 7km radius (considering the house of the infected person as epicentre), which includes Dhanbad, Dhansar, Bank Mor and Saraidhela police station areas, as buffer zone.

The district administration started contact tracing of the infected person for the last 20 days (from March 27 to April 15), before the trackman was quarantined at the divisional railway hospital of Dhanbad on April 15.

The trackman deputed at the drawing section of the civil engineering wing of divisional railway manager’s office of Dhanbad was on leave from March 21 to 26 and went to his in-laws’ place at Chas in Bokaro to see his pregnant wife and joined duty at the DRM office in Dhanbad on March 27.

He was living alone in his quarters at DS Colony as his wife was away at Chas.

During the thermal scanning at the gate of the DRM office of Dhanbad on March 25 he was detected with fever on April 15 and subsequently sent to PMCH for testing on the same day where his blood sample was taken and sent to the quarantine ward of the divisional railway hospital.

On Saturday night, the administration on the basis of the sample report released from the PMCH, declared him Covid-19 positive after which he was shifted to PMCH.
