Spain is anticipating that the swine flu epidemic will reach its peak in the country in late November before starting to decline, the government said Tuesday.

Health authorities believe "the peak of contagion" will be - in the last days of November - Health Minister Trinidad Jimenez told reporters.

But she admitted that it was "difficult to predict" how the epidemic would develop.

Spain announced last month it would begin swine flu vaccinations on November 16, later than in many other European countries.

The groups that will be given priority are pregnant women, health workers, members of the security forces and the fire and prison services and those in high-risk groups, including those with illnesses such as cardiovascular or respiratory diseases.

The government plans to have enough stocks of the A(H1N1) flu vaccine to inoculate 60 percent of the population.

More than 5,700 people have died of swine flu worldwide since the virus was first uncovered in April, with most of the deaths recorded in the Americas, according to the World Health Organisation.

At least 63 of the deaths have been in Spain, according the latest toll by the health ministry, issued October 22.

Spain was the first European country to confirm a case of the virus.
