Two more people tested positive for the Vibrio cholerae bacterium, the People hospital 115 in Ho Chi Minh City has said.
The two patients are 25 year old man, Tran Van Em who experienced the symptoms of cholera on April 14 and his 18 month old son, Tran Van Loi who came back his hometown in the Mekong delta province of Tra Vinh on April 19 with his grandmother.
Medical workers from the city Preventive Health Center April 19 came to Te Canal in district 7 where Mr. Em and his son live to take samples for tests after the hospital announced two patients contracted the disease.
Medical officials disinfected the area and raise awareness about the disease and provide residents there with a 5000 liter safe water tank because people living in boat lack hygienic water for drinking.
The city has so far reported seven cholera cases.
