Fever blisters or febrile blisters are recurring eruptions that cause an inflamed area around the lips or perioral region. The primary causative agent is the Herpes simplex virus type 1 (HSV-1). Since fever-induced blisters are unpleasant and can have a negative impact on quality of life, this article discusses their spread, severity, and treatment.
Is it possible for a fever blister to spread?
Yes. Fever blisters are extremely contagious and easily spread. This is due to the fact that the HSV-1 virus is one of the most contagious viruses. Febrile blisters are inflamed lesions that typically appear around the lips and perioral tissues. These lesions can be itchy, have a tingling or burning sensation and usually clear up on their own.To prevent the spread of the virus, it is best to wash hands frequently, refrain from touching others, or sharing objects such as eating utensils and cosmetics.
When does a fever-induced blister get severe?
Herpes-induced febrile blister complications are uncommon. However, some individuals infected with the HSV-1 virus could experience blister outbreaks, while others could be asymptomatic. Nonetheless, herpes infections in patients diagnosed with the condition can spread to other parts of the body, such as the eyes, nose, or genitals. Remember that when a viral blister ruptures, the patient becomes more susceptible to bacterial infection. As a result, one should avoid touching the affected area.
Additionally, you should take special precautions when exposed to infants as they have weaker immune systems, as the infection can sometimes spread to different organs and cause serious diseases. Besides that, if eczema patients get the infection, it can become complicated.
How should I handle feverish blisters?
The blisters are almost always benign and self-limiting. Very rarely, they can lead to complications. Furthermore, they are highly contagious and may reoccur. Thus, it is important to take measures to prevent the spread.
Treatment is usually not required and remains symptomatic and includes proper hydration and rest. If symptoms are bothersome, antiviral therapy can be used. It is worth noting that antiviral therapy does not treat but rather reduces the duration of infection. Doctors may prescribe a topical antiviral medication, which may also help reduce viral replication.
