More than 500 jaundice cases in Shimla

Panwar said the government-run treatment plant uses an outdated technology for reusing the water.

The Ashwani Khud drinking water scheme supplies water to one-third of Shimla's population.

Most of the jaundice cases have been reported from Chotta Shimla, Panthaghati, Vikas Nagar, New Shimla and Kasumpti, a health officer said.

Doctors in the Indira Gandhi Medical College and Hospital (IGMCH) said on an average 15 to 20 patients suffering with jaundice come to the hospital daily. More than 250 patients have been treated in the IGMCH alone so far.

Irrigation and Public Health Minister Vidya Stokes said the government has taken preventive steps to check the further spread of jaundice.

She said water supply from the Ashwani Khad has been temporarily shut till the mixing of untreated water from the sewerage treatment plant is plugged.

Sounding a note of caution, Panwar said the testing of potable water at any level is not done for virus causing hepatitis because there is no such laboratory in the state.

He said quality of water supplied from the Ashwani Khud is not good, which is causing repeated epidemic in Shimla.

In 2007, 2010 and 2013, a large number people in the town tested positive for Hepatitis E, a liver problem caused by the consumption of water contaminated by sewerage.

Planned for a maximum population of 16,000, Shimla is home to 170,000 people as per the 2011 census and generates 30.09 million litres per day of sewage.
