“Many people who have died of H1N1 swine flu in the United States have also had bacterial infections, health officials reported on Wednesday.

A study of 77 patients who died of the new pandemic H1N1 virus showed 29 percent of them had so called bacterial co-infections, the U.S. Centers for Disease Control and Prevention reported.

About half of these had Streptococcus pneumoniae, which can be prevented with a vaccine, the CDC said. It said doctors may be missing these infections in people severely ill with flu.”
