The number of confirmed cases of the swine influenza A-H1N1 virus is still rising.
The World Health Organization said 33 countries have reported nearly 6,500 swine flu cases. That figure does not include Belgium, which confirmed its first infection on Wednesday.
The latest tally comes as the WHO meets with experts Thursday to decide whether drug makers should switch to producing a vaccine for swine flu, instead of seasonal flu. Companies can only make one vaccine at a time.
More than 2,400 cases of swine flu have been confirmed in Mexico, which is also the location of almost all the deaths from the virus. Mexican authorities have raised the country's death toll to 60, though they said the outbreak there is declining.
The United States has reported even more cases than Mexico -- more than 3,300 -- with three deaths. Swine flu also has killed one person in Costa Rica and one in Canada.
Swine flu cases have also been confirmed in Argentina, Australia, Austria, Brazil, Britain, China, Colombia, Cuba, Denmark, El Salvador, Finland, France, Germany, Guatemala, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Panama, Poland, Portugal, South Korea, Spain, Sweden, Switzerland and Thailand.
The WHO said it is not recommending travel restrictions related to the outbreak.
On Wednesday, Peru lifted a ban on airline flights to and from Mexico, two weeks after it was put in place.
