What condition is typically caused by herpes simplex type 1?

1. Genital blisters

2. Fever blisters around the mouth

3. Burning during urination

4. Painless sores

The correct answer is: Fever blisters around the mouth

Herpes simplex type 1 (HSV-1) is most commonly associated with the development of fever blisters, also known as cold sores, around the mouth. These painful sores typically appear in response to triggers such as stress, illness, or sun exposure. The virus resides in the nerve cells and can become reactivated, leading to recurring outbreaks. Fever blisters are characterized by their clustered appearance and the way they can cause discomfort and itching during their development. The primary reason that this condition is correctly attributed to HSV-1 is the virus's well-documented role in oral herpes infections, which contrasts with HSV-2, more commonly associated with genital herpes. Other conditions listed may be attributed to different infections or types of herpes. Genital blisters are usually caused by HSV-2, while symptoms like burning during urination can indicate a urinary tract infection or could be associated with genital herpes. Painless sores could refer to other conditions such as syphilis rather than HSV-1. Thus, fever blisters around the mouth is the direct and specific manifestation of infection caused by herpes simplex type 1.
