Argentina reported its first death from swine flu, with the health ministry saying the victim was a three-month-old female baby.
The infant died at the Hospital Posadas in Buenos Aires yesterday, where she has been since early June, officials said.
In its daily report, the health ministry said that the number of people in Argentina infected with the swine flu has reached 733, after 89 new cases were confirmed yesterday.
Four of those infected are in intensive care, and three of them are on assisted breathing, the ministry said.
Health experts believe the virus will spread in the southern hemisphere as the region enters the winter season.
The A(H1N1) virus, which was first detected in Mexico in April, has so far infected almost 36,000 people in 76 countries and claimed 163 lives, according to the latest World Health Organisation figures.
