A new strain of avian flu virus that was found in China two months ago has appeared in Vietnam, health experts have confirmed.
The new strain, 220.127.116.11 C, which has
been detected through epidemic investigations, is highly toxic and
therefore extremely deadly, Diep Kinh Tan, Deputy Minister of
Agriculture and Rural Development, said at a meeting on September 4 to
review the epidemic situation.
The 18.104.22.168 C strain has recently spread to Vietnam and is now
present in affected areas in seven provinces and cities, namely
Haiphong, Ha Tinh, Ninh Binh, Nam Dinh, Bac Kan, Thanh Hoa and Quang
Ngai, said Hoang Van Nam, head of the Department of Animal Health
As the new strain is different from the A/H5N1 virus, the ministry is
to conduct experiments and tests to confirm if the vaccines that are
being used to combat A/H5N1 are also effective against the new strain.
If the existing medication is ineffective, studies on new vaccines
against the new strain should be conducted soon, Tan said, adding that
he has asked the DoAH to isolate the virus for this purpose.
The Central Veterinary Diagnosis Center is also monitoring and
looking into the new strain to help find a specific medication against
The avian flu has so far this year severely impacted the seven
above-mentioned provinces and cities, with more than 181,000 ducks and
chicken having died or been culled, the DoAH reported.
Most of these provinces are involved in smuggling poultry from China
that might have carried pathogens that were then spread to domestic
poultry, the department said.
