An official from the US Centers for Disease Control and Prevention (CDC) told the Associated Press news agency that there was no confirmation of any link between the two outbreaks. A WHO spokesman said 12 out of 18 samples taken from the Mexican victims showed they died from a virus with the same genetic structure as the one found in the US.
The WHO would convene an emergency meeting in the "very near future" to determine whether the event constituted a "public health event of international concern", Gregory Hartl told Reuters news agency.

'No contact''No contact'
In the US, experts say the seven people who fell ill across two states were suffering from a new form of swine flu that combined pig, bird and human viruses.In the US, experts say the seven people who fell ill across two states were suffering from a new form of swine flu that combined pig, bird and human viruses.
"This is the first time that we've seen an avian strain, two swine strains and a human strain," Dave Daigle, a spokesman for the CDC, told AFP.
The CDC said none of the seven victims had been in contact with pigs, which is how people usually catch swine flu.The CDC said none of the seven victims had been in contact with pigs, which is how people usually catch swine flu.
It was tracking those who had been in contact with the seven to see if they were ill, it said. All seven had made a full recovery. CDC spokeswoman Anne Schuchat said that officials did not yet know how widely the virus had spread.
But she pointed out that all seven victims had recovered. "So far this is not looking like very very severe influenza," she said.
While the world has been worried over the past few years about the impact of a pandemic originating from avian flu, the WHO say that swine flu has been implicated in the emergence of two of the last century's influenza pandemics, reports BBC science reporter Matt McGrath.
Pigs can serve as a mixing vessel for both human and avian viruses that could combine to create a more virulent strain, our reporter adds.
