Texas health officials have confirmed the first death of a United States resident with swine flu.
Authorities say the woman — who was in her 30's — lived in Cameron County, along the border with Mexico, and had other, chronic health conditions.
Details on those conditions weren't immediately released.
The Texas Department of State Health Services says the woman died earlier this week.
Last week, a toddler boy from Mexico City died at a Houston hospital — making him the first swine flu death in the U.S.

The tally of confirmed swine flu cases in the United States jumped Tuesday to 403 in 38 states, but officials said that's largely from catching up on a backlog of lab tests rather than a sudden spurt in new infections.
The CDC knows of 35 swine flu-related hospitalizations in the U.S.
U.S. health officials are no longer recommending that schools close because of swine flu.
The government last week advised schools to shut down for about two weeks if there were suspected cases of swine flu. Hundreds of schools around the United States have followed that guidance and closed schools.
Health and Human Services Secretary Kathleen Sebelius said Tuesday that the swine flu virus had turned out to be milder than initially feared. She says the government is changing its advice on closing schools.
Sebelius says parents should still make sure to keep sick children at home.
