9. Cold Sores: The Painful, Contagious Skin Blisters
Blisters and Sores: Recognizing the Stages of a Cold Sore
Cold sores, also known as fever blisters, are small, painful blisters that typically appear on or around the lips. They are caused by the herpes simplex virus (HSV), which is highly contagious. Cold sores usually start as a tingling or burning sensation in the affected area, followed by the appearance of fluid-filled blisters that eventually break open and crust over.
Triggers and Transmission: Factors that Influence Cold Sores
Cold sores can be triggered by various factors, including stress, fatigue, hormonal changes, sunlight, and a weakened immune system. The virus that causes cold sores is easily spread through close personal contact, such as kissing, as well as sharing utensils, towels, or other personal items with an infected person.
Treatment and Prevention: Managing Symptoms and Reducing the Risk of Transmission
There is no cure for cold sores, but antiviral medications, such as acyclovir, valacyclovir, or famciclovir, can help reduce the duration and severity of symptoms. Over-the-counter creams and pain relievers may also provide relief from discomfort. To prevent the spread of the virus, it’s important to avoid close contact with others, especially newborns, pregnant women, and individuals with weakened immune systems, while experiencing an active outbreak.
