Three more patients have been diagnosed with cholera in the northern province of Ha Nam, and Ho Chi Minh City on Wednesday said it had admitted a patient from the southern province of Tay Ninh.
So far, the debilitating and sometimes fatal intestinal disease, which severely infected hundreds of people in northern Vietnam in 2008 and 2009, has stricken seven provinces and cities in the north and south, including Hanoi and the southern hub.
The three patients in Ha Nam were among 47 people who fell sick with acute cholera after attending a wedding party on April 22, Nguyen Lap Quyet, director of Ha Nam's health department said in An Ninh Thu Do on Tuesday.
An initial inspection showed that some food at the party was infected with the bacteria that causes cholera, but tests on water didn't find it, Quyet said.
At the HCMC Hospital for Tropical Diseases, director Nguyen Tran Chinh said the 23-year-old man from Tay Ninh was transferred from Tay Ninh General Hospital in critical condition.
He fell sick on April 30 and tested positive for the bacteria last Sunday, Chinh said.
