With just over a month to go until the Olympic Games, public health measures are being intensified in major traffic centers.

CCTV reporter takes us to see a bird flu emergency drill at the Capital International Airport in Beijing.

Beijing airport's Terminal 3 (T3) is on alert.

The airport is testing its bird flu emergency plan.

The infrared sensors detect a high fever and quarantine inspectors immediately send the man for a medical check.

Records show the man came from a bird flu affected area. With 39-degree temperature, he's to be quarantined. The decision is reported up the chain, and an emergency plan goes into action.

Within minutes, disinfection begins and the man is transferred to the hospital.

Dogs are brought in to help inspect luggage and those who had close contact with the patient are given protection tips.

Wei Chuanzhong, Senior National Inspection Official, said, "We have set up 9 emergency plans. Once a contingency happens, they will be started immediately."

Bird flu is a matter of concern for the whole world. Experts say the best defense is a high level of awareness.
