Authorities in Mexico announced three more swine flu deaths and the U.S. and Canada one more death each as the world's largest vaccine maker signed a deal with the U.S. to produce a swine flu vaccine.
The World Health Organization says at least 46 countries have confirmed more than 12,950 swine flu cases. The Mexican death toll now stands at 83, and Canada's is two. The U.S. death is the 12th in the country.
Damon Arnold, a physician who is director of the Illinois Public Health Department said the latest victim, a Chicago-area resident, had other medical conditions, but authorities released no other information about the person.
In the U.S., federal health authorities have confirmed 6,700 swine flu cases, most of them mild. But New York health officials reported another death over the weekend.
In Canada, officials said Monday that a Toronto man who had swine flu but also suffered a chronic medical condition died Saturday.
