Swine flu has become widespread in the United States, with cases in 30 states and more expected to turn up in other states in the next few days, federal health officials reported on Sunday.
Around the world, 19 countries have now been affected, including Colombia, which earlier in the day reported the first confirmed case of swine flu in South America. About 800 people have been infected, predominantly in North America. Spain has 44 confirmed cases, more than any other European country, with Britain, Italy and Germany reporting new cases, The Associated Press reported.
Dr. Anne Schuchat, the interim Deputy Director for Science and Public Health at the Centers for Disease Control and Prevention, said at a news conference here that the virus was “circulating all over” the United States.
