Which of the following infectious diseases does OSHA's Bloodborne Pathogen Standard NOT regulate in the occupational setting?

OSHA's Bloodborne Pathogen Standard (29 CFR 1910.1030) regulates occupational exposure to bloodborne pathogens — specifically microorganisms present in human blood that can cause disease when transmitted to humans. The standard primarily covers HIV, Hepatitis B (HBV), and Hepatitis C (HCV). Malaria, caused by Plasmodium parasites, is transmitted by the bite of infected Anopheles mosquitoes (vector-borne), NOT through blood contact in occupational settings. Therefore, it is not regulated under the Bloodborne Pathogen Standard. OSHA does regulate other bloodborne pathogens including syphilis and Ebola virus, but malaria's vector-borne transmission mechanism places it outside this standard's scope.
