The avian influenza, which had hit the duck-rearing central Kerala's
Kuttanad region, has been brought under control.
So far, as many as 1.80 lakh ducks have been culled and the operation would be wound up on Monday with culling of another batch of 50,000 poultry.
Kerala Health Minister V S Shivakumar said the virus which was identified as H5N1 has not hit humans so far.
However, the government has equipped the hospitals in Alappuzha to face the situation if humans were found affected with H5N1.
Shivakumar added that government has put under observation around 3 lakh persons and visited 80,000 households in the affected areas.
Although duck deaths have been reported from many parts of Central Kerala, tests showed they were not due to avian influenza.
The minister said that the government would extent the financial assistance to the affected farmers in central Kerala.
