Bhubaneswar, Sept. 10 : The state opposition party today gave a call for a shutdown in Orissa to protest against the state Government, as it fails to curb the spread of cholera disease in the tribal belt of the state. Nearly 1,800 people were affected over the past weeks in the tribal areas of Raygada and Koraput districts. Tight security arrangements have been made to avoid any kind of untoward incident during the shutdown.
