Mexico's swine flu death toll rose by three to 106, the health ministry said on Thursday, adding that the number of confirmed infections rose to 5,611.
Of the dead to date, 52.8 percent were women between the ages of 20 and 54, officials said.
All of Mexico's 32 states have registered swine flu cases, with most in the sprawling capital Mexico City.
More than 70 percent of the deceased were aged between 20 and 54 years, the health ministry said in an earlier statement.
Mexican Health Minister Jose Angel Cordova said Monday that the country at the epicenter of the global epidemic might lift its swine flu alert in mid-June, insisting the virus was on the wane.
A(H1N1) flu has now spread to 66 countries with 19,273 people known to have been infected since the disease was first uncovered in April, according to the most recent data from the World Health Organization out on Wednesday.
The WHO is now only updating its tally three times a week, rather than daily.
