- According tests by the Pasteur Institute in southern
Ho Chi Minh City, the specimens from a 26-year-old patient from the city's
Binh Tan district, who died on Wednesday, were positive to the virus strain
H5, while those from a 24-year-old man from Cang Long district in southern
Tra Vinh province, to the virus strain H5N1. The man named Le Hoang Anh
died on Monday in a provincial hospital.

- Relatives of the two patients said they ate chicken
before exhibiting bird flu symptoms. Anh and his relatives ate dead chickens.
The 26-year-old patient bought half of a semi-processed chicken at a local

- The above two deaths in southern Vietnam extend the differences
between H5N1 cases in northern and southern Vietnam. Almost all confirmed
H5N1 cases in southern Vietnam and Cambodia in 2005 died. In contrast the
vast majority of H5N1 cases in northern Vietnam have recovered. These
differences may be due in pat to sequences from mainland china, such as
Yunnan province. Many polymorphisms inVietnam match China. In northern
Vietnam the mild cases have also been associated with H5N1 positive, based
on western blot, contacts, indicating H5N1 is silently transmitting. Although
a lab in Japan did not confirm the tests, reports suggest other labs did
confirm the western blot data showing many contacts were H5N1 positive.
