U.S. Many swine flu deaths linked with second infection

Study : 30% co-infections at dead H1N1 cases

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.

The CDC has already reported that H1N1, declared a pandemic in June, has become more active as weather cools and schools reopened after summer breaks. Cases are reported in all 50 states and it is still circulating globally.
