Abstract In January 2020, the subclade 2.3.4.4h of highly pathogenic avian influenza (H5N6) virus infected migratory whooper swans and mute swans in Xinjiang, western China. The virus is lethal to chickens and ducks but has low pathogenicity in mice. Antigenically, this subclade is similar to the H5N1 vaccine seed virus Re-11.

Abstract An outbreak of low-pathogenicity avian influenza A(H7N3) virus of North American wild bird lineage occurred on commercial turkey farms in North Carolina and South Carolina, USA, during March-April 2020. The virus mutated to the highly pathogenic form in 1 house on 1 farm via recombination with host 28S rRNA. PMID: 33030423 [PubMed - as supplied by publisher]

Background: On January 9th, 2017 a community health worker notified of increased number of deaths in backyard poultry in a pig rearing village of Rajshahi district, Bangladesh. We investigated the reported morbidity and mortality among backyard poultry in Rajshahi to confirm there was an ongoing outbreak of avian influenza, determine the etiology, and identify possible associated illnesses in humans and pigs.

(Penn State) Small-scale poultry farmers in Vietnam tend to respond to viral outbreaks of highly pathogenic avian influenza (HPAI) by rapidly selling their birds as a way to avoid financial loss, according to a new study by an international team of researchers. As these birds are commingled with other birds in markets and trading networks, this practice may increase the likelihood of widespread disease transmission.

Over the past few years, Professor Zhang Yongzhen has made it his business to sequence thousands of previously unknown viruses. But he knew straight away that this one was particularly nasty. It was about 1:30 p.m. on Jan. 3 that a metal box arrived at the drab, beige buildings that house the Shanghai Public Health Clinical Center. Inside was a test tube packed in dry ice that contained swabs from a patient suffering from a peculiar pneumonia sweeping China’s central city of Wuhan. But little did Zhang know that that box would also unleash a vicious squall of blame and geopolitical acrimony worthy of Pandora herself....

Avian influenza outbreaks have been occurring on smallholder poultry farms in Asia for two decades. Farmer responses to these outbreaks can slow down or accelerate virus transmission. We used a longitudinal survey of 53 small-scale chicken farms in southern Vietnam to investigate the impact of outbreaks with disease-induced mortality on harvest rate, vaccination, and disinfection behaviors. We found that in small broiler flocks ( ≤16 birds/flock) the estimated probability of harvest was 56% higher when an outbreak occurred, and 214% higher if an outbreak with sudden deaths occurred in the same month. Vaccination and dis...
