Four VIetnamese have fallen sick after contracting bacteria from pigs with blue ear disease this week, the director of Hanoi-based National Hospital for Tropical Diseases said Wednesday.
They got the Streptococcus suis bacteria by eating uncooked pork, Dr. Nguyen Van Kinh said. All of them came from northern provinces that recently reported blue ear outbreaks.
According to Kinh, two of the people were in critical condition when admitted to the hospital.
Those affected by the bacteria often experience fevers and internal bleeding that can be fatal without timely and proper treatment, he noted.
Blue ear disease has stricken nine provinces and cities in the northern and central regions of Vietnam this year with tens of thousands of affected pigs, the Animal Health Department at the Ministry of Agriculture and Rural Development reported on Tuesday.
Its recurrence was reported in the northern province of Hai Duong on April 3, nine months after the department announced that Vietnam had successfully curbed the spread of the disease together with foot-and-mouth disease and bird flu last June.
