As the bird flu spreads from China to Taiwan, people are worried it may spread farther into a pandemic. Taiwan reported an incident where a man that often travels to China for work has contracted the virus. Test revealed that he was infected with the H7N9 bird flu virus.
The patient in Taiwan said he was never exposed or around birds or eaten any uncooked poultry. Things like this have puzzled scientists and led some to suspect that an animal other than birds is spreading the virus to humans, but no other animal was found to be infected.
