Nhan Dan - Acute diarrhoea reoccurred in three localities, Bac Ninh, Haiphong and Ninh Binh, said the Department of Preventive Medicine and Environment, the Ministry of Public Health.

In Bac Ninh province, 31 patients were tested positive to cholera bacteria. The figure was put at five for Haiphong.

In Ninh Binh province alone, 16 people suffered from acute diarrhoea and were suspected to have been infected with cholera.

Since March 5, 3,700 people have been infected with acute diarrhoea and of the figure, 600 people were tested positive for cholera.

Nguyen Huy Nga, head of the Department of Preventive Medicine and Environment, said that the previous out-break had yet to be completely controlled.

In addition, hot weather in combination with unsafe food consumption and poor sanitation practices will provide favourable conditions for the epidemic to spread.

Therefore, the Ministry of Public Health warns localities, where the epidemic had occurred, of following close guidelines on food safety and sanitation to prevent a possibility of the epidemic's outbreaks.
