WASHINGTON (WVLT) -- On Sunday, American health officials declared a public health emergency over the increasing number of swine flu cases.
In a news conference, the Centers for Disease Control said there were already 20 confirmed cases in the United States, and that number is expected to grow.
Most of those cases are considered to be mild and officials urged the public not to panic.
According to the New York Times, there are 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.
Only one person who tested positive for the disease in the U.S. has been hospitalized.
