The total number of reported cases has now risen to 106, with 21 new infections confirmed by the health department on Tuesday. According to health officials, eight more water samples collected on Monday have failed the potability test. All failed samples - including water provided through tankers by the Patiala municipal corporation - were found to be contaminated with bacteria.

When questioned about the contaminated tanker water, Singh said the matter was under investigation. Deputy commissioner Dr Preeti Yadav visited the affected area. Patiala civil surgeon Dr Jagpalinder Singh said new health teams have been deployed for door-to-door surveys....
