Nebraska health officials are advising summer camp operators and participants to take precautions against swine flu.

Nebraska's chief medical officer, Dr. Joann Schaefer, says the federal Centers for Disease Control and Prevention has issued guidance on how camps can handle ill attendees and promote safe infection control practices.

Among other things, Schaefer says camp personnel should have a plan with parents regarding how illnesses or health emergencies will be handled.

Camp staff should be trained on infection control practices, how to recognize influenza-like illness and how to report possible cases to camp leadership.

Staffer also are encouraged to routinely clean common areas and items that are likely to have frequent hand contact.
