Fifty-three people have died, including three in the United States.
A look at Illinois swine flu cases
Illinois health officials have updated the state's swine flu numbers. A case is "confirmed" when additional laboratory testing backs up initial test results. Until then, the case is called "probable."
The state began doing its own confirmation tests on May 3, which meant quicker turnaround on results and large increases in confirmed cases.
The tally, as time goes on, will show largely the most serious cases because doctors are following the state's recommendation to test only severely ill patients. The virus has turned out to be milder than initially feared, so many mild cases may not be counted.
