BEIJING (AP) — The World Health Organization says there's no evidence that a new strain of bird flu in China is spreading easily among humans even though a few people who were close to patients with the virus have fallen sick.
Dr. Michael O'Leary, head of WHO's office in China, said 15 global and Chinese health experts are on a weeklong mission in Beijing and Shanghai to learn more about the H7N9 bird flu virus has killed 17 people and sickened 70 others.
O'Leary says a major focus of the mission is to learn how the virus infects humans.
The experts will also study a few "clusters" of confirmed and potential infections that have emerged in the past three weeks though he says there has been no evidence of sustained human-to-human transmission.
