Chinese health officials have confirmed a new case of bird flu in a man hospitalized in critical condition in Guangdong province, near Hong Kong.

The case has caused Hong Kong to declare a three-week ban on live poultry from the mainland.

Chinese state media say the infection brings the country's total of human cases of bird flu to 19. Reports say the 31-year-old patient in the town of Shenzhen developed fever and pneumonia-like symptoms June 3.

Earlier Thursday, the World Health Organization confirmed that a seven-year-old Indonesian girl who died last month was infected with bird flu. That means 38 people in Indonesia have now died of bird flu.

Avian flu has killed more than 125 people around the world since late 2003. Most of the victims have been in Asia.
