WASHINGTON -- The number of confirmed cases of swine flu in the United States continued to rise Monday to exceed 2,600 in 44 states but has slowed from the dramatic uptick seen at the weekend, an official report showed.
In a daily update on the number of people who have the (A)H1N1 influenza virus, the Centers for Disease Control and Prevention said there were 2,618 cases in all the states except for Alaska, Arkansas and Mississippi in the south, and Montana, North Dakota and Wyoming in the north.
The new figure marks a rise of 86 since Sunday, when the CDC reported 2,532 confirmed cases of the new strain of swine-origin flu in the United States.
On Friday and Saturday last week, some 600 new cases were reported by US health officials.
The United States is now the nation most affected by the new flu virus, having surpassed Mexico, where the outbreak was first reported last month by the World Health Organization (WHO).
But just three deaths in the United States have been blamed on the virus, compared with 48 swine flu deaths in Mexico.
Canada and Costa Rica have also reported one death each due to swine flu.
Although A(H1N1) flu has been mild in the United States, the CDC warned that there would likely be "more cases, more hospitalizations and more deaths because the population has little to no immunity against it."
