SUBJECT: AVIAN INFLUENZA UPDATE - MORE DEAD DUCKS IN NEW ANIMAL 
OUTBREAK IN CENTRAL VIETNAM 
 
REF: A. HANOI 1793 B. HANOI 1771 C. HANOI 373 
 
1.(U) Summary.  Local and international media outlets reported an 
outbreak of highly pathogenic H5N1 influenza A (AI) among ducks in a 
central Vietnamese province.  Initial reports on a Government of 
Vietnam (GVN) website state that laboratory testing confirmed the 
link to H5N1.  Quang Tri recently experienced seasonal flooding 
enhanced by the effects of Typhoon Lekima (Ref B).  Prior to this 
flooding, Quang Tri had not reported any infections during the most 
recent wave of H5N1 outbreaks.  This incident appears unrelated to 
the recent outbreak among ducks in Tra Vinh province in the Mekong 
Delta (ref A).  GVN officials just formally confirmed that the 
earlier Tra Vinh deaths were caused by H5N1.  End Summary. 
 
¶2. (U) An October 24 report on a GVN Department of Animal Health 
website (http://www.cucthuy.gov.vn) stated that authorities recently 
discovered 290 dead and an additional 20 ill ducklings among a flock 
of 600 two-month-old birds at one farm in Nhi Ha village, Gio Thanh 
commune, Gio Linh district, Quang Tri Province in central Vietnam. 
Gio Lanh is located approximately 100 kilometers north of Danang and 
50 kilometers north of Hue.  The UN Food and Agricultural 
Organization reported that none of the ducks (all of which were 
culled following the outbreak) had been vaccinated. Gio Lanh 
district lies along the coast in an area that recently experienced 
heavy seasonal flooding that resulted in four human deaths.  Though 
the area does not have intense poultry breeding, locally extensive 
rice cultivation supports free-ranging duck populations. 
 
¶3. (U) According to the Department of Animal Health report, tests by 
a national animal laboratory confirmed that the H5N1 strain caused 
the outbreak.  National officials are cooperating with provincial 
authorities, which initially responded to the outbreak.  Quang Tri 
previously had not reported animal outbreaks during the recent waves 
of H5N1 animal infections, which began in December 2006 (ref C). 
There are no reports of suspected human AI infections. 
 
4.(SBU) Though this incident appears unrelated to the recent 
outbreak among ducks in Tra Vinh province in the Mekong Delta, both 
occurred among unvaccinated flocks in areas suffering from intense 
rains and flooding.  Unlike earlier waves of animal infections, 
these two incidents do not seem to be part of a large-scale or 
nation-wide event.  GVN officials, who just confirmed the link to 
H5N1 in the Tra Vinh duck fatalities, warned that the onset of cold 
weather and increased seasonal duck rearing increases the risk of 
future poultry outbreaks.
