A cholera outbreak has killed up to 70 people after heavy rains caused flooding and unsafe sanitary conditions in eastern India, an official said. «All the deaths have occurred within the span of the last one month,» Chinmoy Basu, a senior official in the state of Orissa's health and family welfare department, said late Monday. The affected districts, Rayagara and Koraput, are about 390 and 500 kilometers (240 and 310 miles) southwest of the Orissa state capital, Bhubaneswar. Medical teams have been sent to the affected areas and the situation is now under control, Basu was quoted as saying by the Associated Press.
