It's not a surprise. It shows that China like other countries that have bird flu in poultry can have human cases.

Our goal was that poultry would not get infected by bird flu and we were successful in this.

We must clarify that China has not been concealing any confirmed or suspected human case of bird flu since the first case occurred in November of last year.

At the moment Switzerland's goal is protecting its poultry from bird flu.

The latest deaths indicate that H5N1 is a particularly virulent pathogen, as we have seen in cases in other countries.

We don't think anyone should be restricting exports of poultry because poultry is perfectly safe. There is no bird flu on poultry farms in Europe except on one turkey farm in France, where all the birds have been slaughtered.
