MONTEVIDEO, July 3 (Xinhua) -- A 56-year-old woman has died of A/H1N1 flu, raising Uruguay's total death toll in the new flu outbreak to four, hospital authorities said on Friday.

    The patient had suffered from diabetes and severe obesity, and was a smoker. Both factors were believed to have helped worsen the situation, said Guido Manini, director of the Military Hospital in Uruguay's capital, Montevideo.

    Two other patients, one 54-year-old in Montevideo and the other60-year-old in Maldonado, 140 km from the capital, died of A/H1N1 flu on Thursday. Both had suffered health problems before contracting the flu, Uruguay's Public Health Ministry said earlier.

    Uruguay's first confirmed death from the flu occurred on Monday, said the ministry, adding that the country now has a total of 132 confirmed infections.

    Uruguay's first confirmed flu cases were detected on May 27, in two young people who had traveled to Argentina.
