Herpetic fever, also known as fever blister, is a contagious viral infection characterized by the appearance of painful, fluid-filled blisters or sores on or around the lips, mouth, nose, or genital area. The most common cause of herpetic fever is the herpes simplex virus type 1 (HSV-1), although the virus type 2 (HSV-2) can also cause this condition.
The initial infection usually occurs during childhood or adolescence and is often asymptomatic or presents with mild symptoms. However, the virus remains dormant in nerve cells and can reactivate, leading to recurring episodes of herpetic fever throughout a person's life.
The primary symptoms of herpetic fever include fever, swollen glands, headache, body aches, and a general feeling of malaise. Soon after, small, painful blisters appear, which eventually rupture and form scabs. These outbreaks typically last 7-10 days, and the sores eventually heal without scarring. However, in some cases, the virus can cause more severe symptoms, especially in individuals with weakened immune systems.
Herpetic fever is highly contagious and can spread through direct contact with an active sore or through contact with infected saliva, genital secretions, or mucous membranes. It is important to note that the virus can be transmitted even when there are no visible sores or symptoms present.
While herpetic fever cannot be cured, antiviral medications can help reduce the severity and duration of the outbreaks. Additionally, maintaining good personal hygiene, avoiding close contact during outbreaks, and using barriers, such as condoms or dental dams, can help prevent the spread of herpetic fever to others.
