In Texas, a woman has apparently become the first US resident to die from swine flu. She is the second person to die from the virus outside Mexico. The first one was a Mexican toddler who died of swine flu in the US in April.
In a statement, the Texas Department of State Health services said it was “reporting the first death of a Texas resident with H1N1 [swine] flu.
“A woman from Cameron County who had chronic underlying health conditions died earlier this week”, it said.
1,490 swine flu cases have been verified in 20 countries, said the World Health Organisation (WHO) earlier.
After Mexico, the country that has seen the greatest number of laboratory-confirmed infections are the US, with 403 cases.
Nations have been urged by the WHO to remain vigilant. The organisation says a global pandemic remained a threat.
