(a) If a safety member, a firefighter, a county probation officer, or a member in active law enforcement develops a blood-borne infectious disease or a methicillin-resistant Staphylococcus aureus skin infection, the disease or skin infection so developing or manifesting itself in those cases shall be presumed to arise out of, and in the course of, employment. The blood-borne infectious disease or methicillin-resistant Staphylococcus aureus skin infection so developing or manifesting itself in those cases shall in no case be attributed to any disease or skin infection existing prior to that development or manifestation.
