Health officials around the world battled Friday to stop the spread of swine flu with schools in Europe closed, as global infections passed the 15,000-mark and more countries announced first cases.
Even US President Barack Obama's visit to France next week was touched by the epidemic when a US official preparing a visit to the Normandy beaches was stricken by the virus and put in isolation.
And China reported its first case of domestic infection.
Figures released Friday by the World Health Organisation showed that swine flu had infected 15,510 people in 53 countries since it was first uncovered last month in the United States and Mexico.
The new tally showed that the Czech Republic, Dominican Republic, Romania, Slovakia and Uruguay had all reported cases to the WHO for the first time.
Most of the new cases were reported by the United States, with 1,163 new infections, bringing its total to 7,927. Mexico also posted a significant rise of 369 cases, bringing its total to 4,910.
And the number of deaths rose to 99 after two more deaths were reported by Mexico and one each by Canada and the United States, according to the latest WHO tally.
But according to figures released by individual governments, the virus has now killed more than 110 people around the world. And in the hours after the WHO updated its figures, two countries announced their first cases.
