There are a lot of different avian flu viruses, and not all of them are as worrisome as H5N1. This news report doesn't differentiate between viral strains, so it may give a bit of a false impression.
Nonetheless, based on this survey, roughly 1 chicken out of 20 in Vietnam carries an avian flu virus of some sort.
Note, these tests were on `Healthy Poultry' - Asymptomatic birds - which makes detection and eradication of these diseases very difficult.

HANOI, Jan. 9 (Xinhua) -- Nearly five percent of 15,000 samples from healthy poultry in different cities and provinces in Vietnam have been tested positive to bird flu viruses, local newspaper People reported Wednesday.
Nearly 1.8 percent of tested waterfowls have bird flu viruses, the newspaper quoted a recent survey by the country's Department of Animal Health as reporting.
Fowls having high rates of bearing the viruses are raised in Lang Son, Ha Nam and Thai Binh in the northern region, Ha Tinh, DaNang and Quang Nam in the central region, and Long An, Dong Thap, Ca Mau and Tra Vinh in the southern region.
Bird flu is now hitting northern Thai Nguyen province and southern Tra Vinh province, said the department.
