Iowa Gov. Chet Culver says the state has two probable causes of swine flu.
Speaking Wednesday at a Statehouse news conference, Culver told reporters that officials would know Thursday if the cases are swine flu.
Officials say one case was from a California resident who visited Scott and Clinton counties last week. The other was a woman who returned from Mexico and traveled through Johnson, Des Moines and Muscatine counties.
State Medical Director Patricia Quinlisk says both of the people infected were now recovering.
Should know by tomorrow if they are confirmed or not.
