A major Iowa hospital and medical clinic system has notified about 1.4 million patients and former patients about a computer breach that might have exposed their personal information.

UnityPoint Health officials say hackers used broke into the company's email system and could have obtained medical information.

UnityPoint's privacy officer, RaeAnn Isaacson, said Monday the company isn't aware of any misuse of patient information related to the incident. But she says the company is telling patients what UnityPoint is doing to address the situation and what patients can do to help protect their information.

The company says the hackers also might have obtained some patients' financial information.

UnityPoint say that after the problem was discovered May 31, it hired outside experts and notified the FBI.
