SHANGHAI, April 5 (Xinhua) -- Authorities in Shanghai on Thursday closed a live poultry trading zone in an agricultural products market and began slaughtering all birds there after detecting H7N9 bird flu virus from samples of pigeon from the market.
Meanwhile, a person who had close contact with a dead H7N9 bird flu patient in Shanghai has been under treatment in quarantine after developing symptoms of fever, running nose and throat itching, the Shanghai Municipal Health and Family Planning Commission said late Thursday.

The commission will also investigate and track where the pigeons came from, it said.
