South Korea on Tuesday confirmed an outbreak of a low pathogenic avian influenza virus in chickens previously tested positive for avian flu, Xinhua quoted the government as saying Tuesday. The Ministry for Food, Agriculture, Forestry and Fisheries said the birds at a poultry farm in South Chungcheong Province were found to have been infected with the low pathogenic H9N2 strain of the avian influenza virus that is less damaging to both birds and humans. Quarantine authorities conducted thorough examinations after six of 10 chickens at the farm tested positive for avian flu. Some 100 chickens at the farm had shown symptoms of avian flu. The ministry ordered the affected farm to remain under watch until restrictions on travel to and from the site will be removed.
