'Too late' to contain swine flu

The swine flu virus first detected in Mexico can no longer be contained and countries should focus on mitigating its effects, a top UN official said.
World Health Organization deputy chief Keiji Fukuda was speaking as the WHO raised its alert level to four, or two steps short of a full pandemic.
UN food inspectors are going to Mexico to examine reports that industrial pig farms were the source of the outbreak.
The number of probable deaths from the virus there has risen to 152. 
New Zealand confirmed at least three cases on Tuesday, and Israel one.
The US, Canada, Spain and Britain confirmed cases earlier but no deaths have been reported outside Mexico.
