Avian flu virus is spreading rapidly in several Asian countries, according to Itar-Tass.
The virus spread started back in 2013, when in China a person was diagnosed with H7N9 strain. From the beginning of 2014 more than 120 got infected with avian flu in China and 39 of them died of it.
Now four avian flu cases were reported in China’s mainland.
Hong Kong authorities said they plan to slay 15 thousand hens to avert an infection outbreak.
A blood test for this virus in several birds from poultry supply made from neighbouring province Guangdong was positive, the South China Morning Post newspaper reported.
First human H7N9 infection case since the start of this winter was reported in the Chinese Special Administrative Region several days ago. A 68-year-old woman got infected.
She visited a neighbouring city of Shenzhen in southern China’s Guangdong Province not long before that. She is still estimated to be in severe condition.
A new avian flu break was reported in Japan, as this epizootic infectious disease was observed in the south of the country in Yamaguchi Prefecture.
A virus outbreak was exposed at a farm in the city of Nagato, where 20 hens died of avian flu. A 3-kilometer quarantine zone was created around a poultry farm with a ban imposed on its produce delivery.
As many as 42 thousand hens were also slaughtered in another southern prefecture Miyazaki.
In 2014 three avian flu breaks have occurred in Japan that made poultry farmers kill around 150 thousand hens.
There is yet no proof that this disease strain is transmitted from human to human.
Avian influenza — known informally as avian flu or bird flu — refers to “influenza caused by viruses adapted to birds. The version with the greatest concern is highly pathogenic avian influenza (HPAI).
“Bird flu” is a phrase similar to “swine flu,” “dog flu,” “horse flu,” or “human flu” in that it refers to an illness caused by any of many different strains of influenza viruses that have adapted to a specific host.
All known viruses that cause influenza in birds belong to the species influenza A virus. All subtypes (but not all strains of all subtypes) of influenza A virus are adapted to birds, which is why for many purposes avian flu virus is the influenza A virus. (Note, however, that the “A” does not stand for “avian”).
