Current flu infection control measures in hospitals may be inadequate, according to an article on the U.S. News and World Report website.
A new study has found that hospital workers and patients can spread the flu before they show any symptoms.
During the flu seasons studied, 11 percent of the healthcare workers and 4 percent of the patients were diagnosed with a flu infection. Two of the staff and two of the patients had no flu symptoms.
Seventeen percent of the flu-positive swabs collected from healthcare workers and eight percent of 38 flu-positive swabs from patients were obtained on days when they had no flu symptoms.
