COLUMBIA State health officials say South Carolina has 16 confirmed cases of swine flu.
Department of Health and Environmental Control spokesman Jim Beasley said today that the Centers for Disease Control and Prevention had confirmed three cases to add to the 13 reported on Saturday.
Of those cases, 15 are related to a Newberry private school students' trip to Mexico, where the virus first appeared. The 16th case is in Laurens County.
Mr. Beasley said some people have been asked to take voluntary steps of isolation, in which people who show symptoms are separated from the healthy population, and quarantine, when people who have been exposed are asked to stay away from healthy people.
