Herpes Simplex Virus Type 1 is commonly found in which location?

• A. Mouth
• B. Genitalia
• C. Hands
• D. Lungs

Answer: (A)

Herpes simplex virus type 1 is most closely associated with the orofacial region. After the initial infection, it becomes latent in the trigeminal nerve ganglia and tends to reactivate as recurrent sores on the lips and inside the mouth. That oral or orofacial involvement is why the mouth is the location most commonly associated with HSV-1. While HSV-1 can occasionally infect the genital area (often through oral-genital contact), and there are rare cases of hand infections (herpetic whitlow) or other sites, these are not the typical reservoirs. So the mouth is the best-supported location for HSV-1 in usual conditions.
