The H5N1 outbreak in Kerala state may be spreading. Via The New Indian Express: Bird Deaths in District Attributed to Viral Infection. Excerpt:
Even as numerous birds continue to die in the district, the Health Department is yet to confirm whether the district has come under the grip of avian flu. Three hundred chickens and one migratory bird were found dead at a farm in Puthencruz village and Aluva respectively on Thursday.
On Wednesday, 30 ducks were found dead in Kalady. Though the tracheal swab of 20 was sent to ADDL lab, Thiruvalla, the authorities said they were finding it difficult to identify the virus. DMO Dr Haseena Mohammed said the death of 300 birds could be attributed to natural causes.
Nedumbathil Kuriachan who lost 300 chickens said that around 200 died at an interval of 12 hours.
“There are 4,000 chickens in my farm. It is normal for 50 to 100 to die owing to climate change in an interval of one or two weeks.
“This is the first time that we are witnessing such mass death. Now the condition of around 100 chickens is serious and they are likely to die by morning,” said Kuriachan.
The 4000 chickens were brought from a nearby place four weeks ago after paying Rs 40 for each.
“The doctors who visited the farm said viral infection was the cause of death. They have taken the tracheal swab, serum samples and droppings to the lab,” Kuriachan said.
If I recall correctly, earlier H5N1 outbreaks have tended to occur in India's northeast, especially West Bengal. Now H5N1 has crossed the subcontinent to the far southwest, which implies its existence across a great swath of India.
