American health officials announced Sunday they had confirmed 20 cases of swine flu across the United States, and they said the number of infections was likely to grow as investigators fan out to track down the path of the outbreak.
“We are seeing more cases of swine flu,” said Richard Besser, acting director of the Centers for Disease Control, in a news conference in Washington. “We expect to see more cases of swine flu. As we continue to look for cases, I expect we’re going to find them.”
Officials said they had confirmed eight cases in New York, seven in California, two in Kansas, two in Texas and one in Ohio, and that the cases looked to be similar to the deadly strain of swine flu that has killed more than 80 people in Mexico and infected 1,300 more.
