As many as 3,434 students of government schools in Kandhamal, Odisha (an eastern Indian state), have tested positive for malaria.
"The affected students are currently under medication. The health officials are keeping a watch on their condition," said Kandhamal District Collector Yamini Sarangi.
According to sources, blood samples of 19,767 students of 214 residential schools run by Scheduled Tribes and Scheduled Castes development department in the district were tested between July 6 and August 3.
The district administration launched a three-month malaria, dengue and diarrhoea awareness drive last week in the district.
"The accredited social health activists and other health workers will follow up the program. They will immediately refer such cases to government hospitals," said Chief District Medical Officer (CDMO) Sapaneswar Gadanayak.
Kandhamal district has recorded two deaths due to malaria this year. Last year, six persons had died of the vector-borne disease and two persons had tested positive for dengue.
