Final answer:
Fever blisters or cold sores are commonly referred to as herpes simplex virus type 1 (HSV-1) in healthcare. They are contagious blisters that appear mostly around the mouth and can be treated with antiviral medications.
Step-by-step explanation:
The healthcare term for fever blisters or cold sores is herpes simplex virus type 1 (HSV-1). These are red, fluid-filled blisters that typically appear near the mouth or on other areas of the face. Once the herpes simplex virus is contracted, it cannot be cured; it remains dormant in the body with the potential to cause new cold sores during periods of stress or certain environmental conditions. While the sores are highly contagious and can be spread through direct contact, the virus can also be transmitted when no visible blisters are present.
HSV-1 is also responsible for other conditions such as acute herpetic gingivostomatitis, which results in ulcers inside the mouth. Treatment, if necessary, may involve antiviral medications like acyclovir, famciclovir, or valacyclovir. Understanding that cold sores and genital herpes are caused by related but distinct herpes simplex viruses (HSV-1 and HSV-2, respectively) is important in recognizing and managing these conditions.
