BHUBANESWAR: Even as Odisha battles with high incidence of diarrhoea among children, the Indian Medical Association (IMA) is all set to launch an extensive programme on ‘Management and prevention of childhood diarrhoea’ to combat the menace in the State. The programme would be launched in five districts of Rayagada, Kalahandi, Nabarangpur, Koraput and Kandhamal in association with Unicef and NRHM. These five districts, which are predominantly tribal, have been witnessing frequent outbreaks of cholera over the recent years.
