GENEVA (AP) - The World Health Organization says it suspects
U.S. swine flu patients may have transmitted the virus to others in
the United States.
Confirmation would indicate the new flu strain is spreading
beyond those travelers returning from Mexico.
The global health agency says so far, most people confirmed with
swine flu were infected in Mexico. But WHO spokesman Gregory Hartl
says the source of some infections in the United States, Canada and
Britain is unclear.
Hartl told reporters in Geneva on Tuesday that WHO suspects
people are infecting others with the disease in other locations
