It is entirely possible that more human cases will crop up now and then across China as outbreaks in poultry continue and as bird flu continues to be endemic in the environment.
As more outbreaks occur among poultry and animals around the world, and as more human cases occur, the virus has more chances to transmit more effectively from animals to humans, or possibly among humans as well.
It's not a surprise. It shows that China like other countries that have bird flu in poultry can have human cases.
The latest outbreak of H5N1 avian influenza in poultry in China shows once again how entrenched this virus appears to be in the environment in this part of the world.
