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.
This is a reiteration of how much of a public health threat bird flu really is. Sometimes it takes a human case or a suspected human case to raise the alarm, to remind us that no country, whether China or anywhere else, can afford to be complacent.
Although this is only a guess, there have been some examples in which human cases of bird flu were reported first and then the animal epidemic.
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 still early days in terms of human cases being found in China. There isn't that much experience perhaps in dealing with possible human cases, and further support might be needed more now than perhaps later.
It just shows you that anything can happen at any time. It's a very unpredictable situation, whether on the human side or the animal side.
It's not a surprise. It shows that China like other countries that have bird flu in poultry can have human cases.
