Chandigarh has reported a case of polio, described by health officials as the first such case that has come to light in the union territory in the last four years.
Adjoining Haryana too has reported three polio cases - two in Sonepat district and one in Faridabad. One polio case was reported from Kurukshetra last month.
Health officials said here Tuesday that the polio-affected child, Meena, was daughter of a labourer from Bihar who had migrated to the city.
The officials said that the health of the girl was being monitored. They appealed to all parents to get their children immunised against polio during pulse polio campaigns conducted from time to time.
Sources in Haryana's health department said that the three cases of polio reported were a setback to their anti-polio drive.
They said that the next phase of the pulse polio campaign would focus on the districts where the polio cases have been detected.
