Doctors attribute contaminated water and hot weather to the epidemic.
They have advised the people to avoid eating stale and uncovered food sold on roadside stalls.
With the advent of summer, the incidence of gastroenteritis has increased in Larkana, Sukkur and other parts of upper Sindh.
Our Hyderabad correspondent adds: Director-General, Health, Services, Sindh, Dr
Hadi Bux Jatoi on Wednesday said that no gastroenteritisrelated death has been reported at any Sindh government hospital so far and claimed arrangements have been made to take special care of gastroenteritis and diarrhoea patients.
Briefing journalists in his office with EDO health Dr Mahfooz Qureshi, he said since April 25, around 4,891 diarrhoea patients have been brought to different hospitals while 1,722 were admitted to the hospitals.
He said a cell has been set up in his office to receive complaints from patients or their attendants regarding the negligence of doctors.
He advised the people to ensure their children stay in homes as much as possible as they are more vulnerable and could be affected by heat.
He said if anyone suffers from diarrhoea he/she should be immediately shifted to hospital to ensure early treatment.
Normally, he said, people bring patients to hospitals after wasting considerable time and by then their condition gets deteriorated.
He said no private health institution is housing an emergency cell and such facility can only be found in the government run hospitals.
