Which of the following would NOT pose a direct risk to the patient if the dentist has it actively?

Measles, mumps, conjunctivitis, and active varicella zoster are all transmissible via airborne, droplet, or close contact routes that are clinically relevant during routine face-to-face dental treatment. Genital herpes is transmitted via genital/intimate contact and poses essentially no transmission risk to a patient during ordinary dental care, making it the exception.
