Diarrhoea has suddenly broken out in Natore district.
Some 50 persons were affected with diarrhoea for two days until Friday in Natore.
The Sadar hospital struggled to accommodate them.
Most of the patients received treatment lying on the floor and so suffered severely for the cold weather.
Residential Medical Officer Abul Kalam Azad said the patients were from Borgachha and Station Bazar areas in the municipality. They might have been affected with this disease after drinking water.
Mayor Sheikh Emdadul Haq Al Mamun said there is no chance of the supply water being polluted as it is drawn from underground directly.
Civil Surgeon Ferdous Nilufer said there were only 16 patients at the hospital until 3pm yesterday. The rest had returned home after receiving treatment.
Replying to a query, she said there are only six beds for diarrhoea patients at the hospital and so the rest of the patients had to take treatment lying on the floor.
“The sample of water will be collected from the affected areas on Sunday and then sent to Dhaka for test. Only then will it be possible to know why diarrhoea spread there,” she added.
