If they do not have a written or online injury report for you to complete, then you should send them a detailed letter stating that you were exposed at work, the symptoms you are having and request medical care. Regardless, of how you notify your employer please keep copies of any and all documents reporting your injury. Injury reports sometimes seem to get lost by employers later on when they claim they were not notified of the injury. Iowa law provides up to 90 days from when you knew or should have known that a condition was work-related, but it is the best practice to report it in writing right away.
