It is possible to get an infectious disease from performing CPR. The risk is low, but there is a risk. That is why the ARC and AHA advise the use of a breathing barrier when performing CPR (even during class practice on the mannequin).
Contact the American Red Cross for a CPR re-certification course. See the related link.
