Shimla: More than 500 cases of jaundice have been reported from this Himachal Pradesh capital in the past few weeks and their number has been increasing each day, doctors said on Wednesday.

Shimla civic authorities suspect that mixing of sewage with the potable water has caused the spread of the water-borne disease. The state high court also took suo motu cognizance in this regard and sought a status report from the government by Thursday.
