Which communicable disease prevention is required for healthcare workers?

• A. Varicella
• B. Hepatitis A
• C. Hepatitis B
• D. Mumps

Answer: (C)

Protecting healthcare workers from bloodborne pathogens is a central goal in occupational health. Hepatitis B, a virus that infects the liver, is highly transmissible through blood and bodily fluids and poses a real risk in settings where needlesticks or exposure to patient materials can occur. Because of this, vaccination against hepatitis B is routinely required by many employers and public health regulations as a standard preventive measure. The vaccine offers strong, long-lasting protection with a good safety profile, making it the most effective and practical line of defense to reduce occupational transmission to both workers and patients.

Vaccines for varicella, mumps, and hepatitis A are important for overall immunity and outbreak control, but they are not universally mandated for all healthcare workers in the same way hepatitis B vaccination typically is.
