What is a fever blister?
A cold sore, also known as herpes labialis, is a viral infection caused by the herpes simplex virus (HSV). It usually manifests as painful sores or blisters on the lips, around the mouth or on the face. Early signs may include itching, burning or discomfort in the affected area.
How do you get a fever blister?
HSV is transmitted mainly through direct contact with a herpes sore or even the saliva of an infected person, even in the absence of visible sores. Sharing personal items such as utensils and towels, or close contact, can also facilitate transmission.
What triggers fever blisters?
Fever blisters can be triggered by a number of factors:
Stress
fatigue
Hormonal changes
Excessive sun exposure
Fever or other illnesses
How can I prevent the appearance of fever blisters?
To prevent the appearance of fever blisters, we recommend adopting a healthy lifestyle, maintaining a strong immune system and avoiding known triggers. Using sunscreen on the lips and face can also help prevent breakouts caused by sun exposure.
How is a fever blister treated?
Fever blisters are treated to reduce pain and speed healing. Treatment options include:
Prescription antivirals, such as aciclovir, can reduce the duration and severity of the rash.
Over-the-counter antiviral creams, applied at the first signs, can help relieve symptoms.
Home remedies, such as applying ice or cold tea bags to the affected area, can offer temporary pain relief.
Is there a permanent cure for herpes simplex virus?
There is currently no cure for herpes simplex virus. However, it is possible to manage symptoms and reduce the frequency of outbreaks through appropriate treatment and prevention of triggers.
Are fever blisters contagious even when they're not visible?
Yes, even in the absence of open or visible sores, fever blisters can be contagious. The herpes simplex virus can be transmitted through what is known as asymptomatic transmission. This means that the virus can spread even if the infected person has no current symptoms. It is therefore crucial to maintain good hygiene practices, such as avoiding sharing personal items and limiting close contact, to reduce the risk of transmission.
Are there any foods to avoid to prevent fever blister outbreaks?
Certain foods can influence the frequency of fever blister eruptions in some people. Foods rich in arginine, an amino acid that can promote replication of the herpes virus, are often cited. These include nuts, seeds, chocolate and wholegrain cereals. It may be beneficial to increase intake of foods rich in lysine, another amino acid that can help control the virus, such as fish, chicken, dairy products and vegetables. However, dietary reactions can vary from person to person, so it's advisable to observe how your body reacts and adjust your diet accordingly.
Can make-up be applied to a fever blister?
It's generally not advisable to apply make-up or any cosmetic product to an active fever blister, as this can aggravate the infection or delay the healing process. It can also contaminate your make-up. If you must cover a fever blister, wait until it has healed properly. Use a disposable product to apply make-up, and avoid sharing your cosmetics with others.
How long does a fever blister last?
The duration of a fever blister can vary, but symptoms generally last between 7 and 10 days. The sores go through several stages, starting with itching and tingling, followed by the appearance of vesicles, which then burst to form a crust. Although symptoms can be uncomfortable, they tend to improve without medical treatment within a few days. However, treatments are available to speed healing and reduce pain.
Can cold sores spread to other parts of the body?
Yes, the herpes simplex virus can spread to other parts of the body if you touch a herpes sore and then another part of your body. It's important to wash your hands frequently and avoid touching cold sores to prevent the virus from spreading. The areas most commonly affected by auto-inoculation include the eyes (ocular herpes) and fingers (digital herpes). Special care should be taken to avoid touching these areas if you have a fever blister.
By adopting preventive measures and being aware of risk factors and treatment methods, you can effectively manage fever blisters and reduce their impact on your daily life.
