OSHA (Occupational Safety and Health Administration) regulates workplace exposure to various infectious and hazardous agents. Which of the following does OSHA NOT regulate?

OSHA regulates occupational hazards in the workplace, including: bloodborne pathogens standard (HIV, HBV, HCV — covering dental healthcare workers exposed to blood and body fluids), hazard communication (chemical safety, SDS sheets), ionizing radiation, and formaldehyde exposure. OSHA does NOT regulate malaria because malaria is a vector-borne disease (transmitted by Anopheles mosquitoes) not acquired through occupational exposure in U.S. dental offices. Malaria falls under the jurisdiction of the CDC for public health guidance, not OSHA for occupational safety. Dental offices do not face workplace malaria exposure risk.
