Czech Republic reports first H5N8 bird flu case in three years
The Czech Republic has its first case of the highly pathogenic H5N8 bird flu virus in three years after an outbreak was reported on a poultry farm in the country's central region, the State Veterinary Administration said on Saturday.
Abstract In January 2020, the subclade 184.108.40.206h 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]
This study provides further insight into the ways that lymphocytes maturate and traffic in response to H7N9 infection in the ferret model.
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.
Covid has got experts thinking urgently about the risk of diseases passing from farmed animals to humans. We examine the major outbreaks of the past two centuriesContinue reading...
By Stephen LeahySep 2 2020 (IPS-Partners) Having reported on SARS, Ebola, Bird Flu (H5N1) outbreaks, as well as writing about efforts to combat HIV, I was horrified by what was going on in Wuhan, China last Jan mainly because of how fast this new SARS-CoV-2 virus spread. By early Feb it seemed likely there’d be a global pandemic and by the end of Feb I started to freak out as the pandemic took hold. I’ve never been to Wuhan or China nor seen anyone who had; and I hadn’t travelled any where recently. It was nearly impossible for me to have encountered the virus but that didn’t keep me from getting si...

(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....
