GREENVILLE - South Carolina is one of three Southern states reporting an uptick in H1N1 flu that health officials are investigating.
Alabama and Georgia also are seeing an increase, according to the U.S. Centers for Disease Control and Prevention.
"The H1N1 virus is still circulating, and people continue to become ill, be hospitalized and die from this virus," said the CDC's Dr. Anne Schuchat.
About 60 million Americans have been infected, 265,000 have been hospitalized and 12,000 have died, U.S. Surgeon General Regina Benjamin said. Most have been adults with health problems such as asthma, chronic obstructive pulmonary disorder and other lung conditions, cancer, diabetes and heart disease.
Most hadn't been vaccinated, she said.
