Final answer:
Herpetic lesions caused by HSV-1 usually appear on the lips, mouth, and face, and are referred to as cold sores or fever blisters. These lesions are highly contagious and can also manifest on other body parts. They are treated with antiviral medications when needed.
Step-by-step explanation:
Common Sites for Herpetic Lesions
The most common sites for the appearance of herpetic lesions caused by Herpes Simplex Virus type 1 (HSV-1) are on the lips, mouth, and face. These infections often frequently manifest as oral herpes, also known as cold sores or fever blisters. When lesions are present, they can blister, break open, and form crusts. HSV-1 lesions can also occur on other parts of the body, such as the fingers, known as herpetic whitlow, or in athletes, as herpes gladiatorum on the neck, shoulders, and trunk.
Initial symptoms can resemble a cold, with a high fever followed by a rash. As it is highly contagious, the virus can be spread by direct contact even when an individual is asymptomatic. HSV-1 can be latent, residing in nerve ganglia, and reactivated by factors such as stress. Acyclovir and other antiviral medications might be used for treatment when necessary.
