Two additional vehicles have been made available from Health Block Tauni Devi for the teams working in the field, the DC said.?

At least two to three people in every household fell sick after consuming contaminated water provided by the Jal Shakti department, Rajeev Kumar, the head of Rangas panchayat, had said on Sunday.??

It is believed that the high amount of bacteria in the water caused the sickness, he said, and attributed it to contamination of the pit from which the water is supplied.??

Villagers said the water was supplied unfiltered from an under-construction tank. The report of water samples is still awaited.??

Chief Minister Sukhvinder Singh Sukhu, who is also the MLA from Naudan, has directed the district administration and the health department to take proper care of the patients and ensure there is no shortage of medicines and other items.
