Beauty and wellness professionals must be prepared to deal with all EXCEPT which of the following types of potentially harmful infectious disease organisms?

• A. Gases
• B. Bacteria
• C. Viruses
• D. Fungi

Answer: (A)

Infection control focuses on living microorganisms that can cause disease—bacteria, viruses, and fungi. These are the agents you’re trained to recognize, contain, and prevent from spreading through proper sanitation, disinfection, and personal hygiene. Gases aren’t living organisms and don’t cause infections, so they’re not treated as infectious disease organisms in safety training. The other types listed are real pathogens you must be prepared to handle, which is why gases is the correct answer.
