Authorities in India and Taiwan have reported outbreaks of H5N1 strain highly pathogenic avian influenza to the World Organization for Animal Health. 

The case in India involved at least two egg-producing farms in the Nellore region in Andhra Pradesh. In Taiwan, a small-scale commercial farm in Pingtung County was diagnosed with HPAI. 

Appropriate control measures have been implemented although with the high density of chickens in both locations, and also ducks in the case of Taiwan, deficiencies in biosecurity will most probably lead to additional cases. Early diagnosis relies on farmers alerting regulatory officials to clinical signs and mortality to initiate control measures.
