The World Health Organization said more than 15,000 cases of the swine influenza A-H1N1 have been confirmed worldwide, and 99 people have died.

In its latest figures released Friday, the WHO said the disease has officially been reported in 53 countries.

Mexico has the most deaths, with 85, followed by the United States with 11 fatalities.  However, Mexico had the second-highest number of infections, nearly 5,000, behind the United States, with nearly 8,000 cases.

Meanwhile, China has reported its first suspected case of the swine flu in a person believed to have contracted the disease within the country.

The Chinese Health Ministry said the 24-year-old woman came into close contact with a confirmed carrier of the flu earlier this week in Guangzhou.  It said the carrier is a 28-year-old Chinese-American who works at a hospital in New York.

In addition to the WHO figures, Venezuela announced its first confirmed case of the disease.  The officials believe the 22-year-old man contracted the disease during a trip in Panama.
