OIE: H5N1 Detected In Crows Again ? India

While China, Cambodia, Vietnam, and South Korea have garnered most of the avian flu headlines this winter, the H5N1 virus remains endemic in other countries as well, including much of Asia and parts of the Middle East. In many of these regions, surveillance and reporting is less than optimal, so the true extent of this virus is hard to measure.



Although debate over the incidence and importance of wild birds spreading the avian flu virus remains contentious (see India: The H5N1 & Migratory Birds Debate), we have often seen wild and migratory birds test positive for the H5N1 virus.



In addition to having infected more than 20 mammalian species, the H5N1 virus has been detected in more than 150 different types of wild birds (See USGS List of Species Affected by H5N1 (Avian Influenza)).

H5N1 Bird Flu Kills House Crows in Indian State

INDIA - The Indian veterinary authorities have reported an outbreak of highly pathogenic H5N1 avian influenza in the state of Odisha.

The World Organisation for Animal Health (OIE) received an immediate notification on Friday, 21 February. The outbreak was initially observed on 31 January and confirmed on 6 February.

On 6 February, real-time PCR, reverse transcription - polymerase chain reaction (RT-PCR) and virus isolation tests were conducted on the crows at the High Security Animal Disease Laboratory in Bhopal and the tests confirmed the presence of the HPAI virus.

According to the report, two house crows (Corvus splendens) were found dead. No birds were slaughtered and/or destroyed.

The source of the outbreak remains inconclusive.

The OIE, in conjunction with the country's competent authorities, have disinfected infected premises/establishments to contain the situation. However, vaccination of birds has been prohibited; there has also been no treatment of affected birds.
