The Ministry of Agriculture ruled out all these kinds of rumors and there is no outbreak and not any human cases.

Nobody can rule it out. It's premature to say bird flu is under control. Scientifically and operationally, you can't say it's under control, the opportunity is always there.

We are in no position to make an investigation.

This is not a good signal.

If there are frequent outbreaks, that means some measures are not being taken. The repeated outbreaks really is a signal of seriousness and the inability of the surveillance system.

In general we are fairly concerned because we feel the more outbreaks, the more the risk of a pandemic.

The problem in China is about 50-60 percent of the poultry is operated on small-scale farms in the backyard, which provides the ideal life for the virus to jump between different species of poultry.

Migratory birds are being blamed, but once poultry has been infected, it can spread from town to town, especially if people buy the infected poultry.

The frequency of outbreaks is a reflection of the lack of a surveillance system.

In wintertime, we really are concerned because the risk is higher. The more the environment is ideal for the virus the more outbreaks we are expecting.
