Mexico has been dealing with a number of new cases of avian influenza in recent months.Nineteen outbreaks of H7N3 avian influenza in Mexico have been reported to the World Organisation for Animal Health (OIE) between January and March in the states of Jalisco, Puebla and Veracruz. One of the outbreaks was in a small flock of Indian peafowl and 3 others were in backyard flocks.
However, the majority of outbreaks were in commercial flocks of layers or breeders with a total of more than 2.7 million birds affected. Of these, around 14,000 died and more than 145,000 had been destroyed. Several of the affected farms were identified as the result of surveillance, which is continuing in all three states, according to the report.
Avian influenza has also been reported in Myanmar and China. Myanmar had been free of HPAI since February last year, but a so-far unidentified H5 virus has returned to the region of Sagaing in the center of the country. A flock of 500 10-month-old layers was affected, leading to the death or destruction of all the birds.
China’s news agency, Xinhua reports that the authorities in Myanmar have culled 7,000 chickens at 13 farms in the affected poultry farming zone in Monywa in an attempt to stop the virus from spreading further. A quarantine zone has been established and surveillance has been stepped up with no human infections reported so far.
Vietnam reported the loss of a village flock of 200 birds in the northerly province of Nghe An earlier this month. The presence of the H5N1 virus subtype has been confirmed. Two new linked outbreaks of H5N8 HPAI have been reported following testing of native chickens received by a slaughterhouse in the southwestern city of Kaohsiung in Taiwan.
The H2N2 virus was also confirmed in one of the flocks. Almost 1,300 birds were affected in total. After abnormal mortality of 558 birds was observed in 2 flocks of breeding geese in Taibao city in Chiayi County, the H5N2 virus was confirmed and the surviving 3,000 birds have been destroyed.
Despite the recent mild weather that should have helped reduce the spread of HPAI, Focus Taiwan reports that 1,312 geese have been culled at a farm in Chiayi county in the last week after confirmation of a highly pathogenic H5 virus. This brings the number of Taiwanese poultry farms affected by HPAI so far this year to 27.
