The first study of U.S. health care workers with swine flu found that many didn't do enough to protect themselves against the virus.
Researchers focused on 13 nurses and other health care workers who were likely infected at work in the early days of the U.S. outbreak. They found that only half always wore gloves, and even fewer routinely wore other protection around patients who might have the virus.
In late April just as U.S. cases were first mounting the U.S. Centers for Disease Control and Prevention said health care workers should wear gloves, gowns, eye protection and respirator masks when dealing with patients suspected of having swine flu. The CDC also advised sick workers to stay home.
To date, about 80 health care workers have been confirmed with swine flu. The study examined the 26 cases of infected workers with detailed information as of mid-May.
