Genital herpes type I is the most common ulcerative sexually transmitted disease caused by human herpesvirus type 1 (HSV-1) and is usually treated with antiviral drugs.
The diagnosis of genital herpes type 1 usually relies on the clinical finding of characteristic skin lesions. Unlike other herpesvirus infections, clusters of blisters and ulcers appearing on an erythematous base are most often seen on genital herpes. When the diagnosis is unclear, herpes simplex virus testing should be performed.
Genital herpes type I is treated with antiviral medications such as acyclovir, valacyclovir, and famciclovir. These medications reduce viral spread and can alleviate symptoms in patients with severe initial infections. Dosage adjustments are required for renal insufficiency, and oral side effects are less common but may include nausea, vomiting, diarrhea, headache, and rash.
The best way to avoid genital herpes is to maintain good sexual habits, such as having a long-term mutually monogamous sexual relationship with a partner who has been proven to be uninfected. Proper and consistent use of latex condoms can also reduce the risk of genital herpes.
If you experience symptoms of genital herpes type 1 you should seek medical attention as soon as possible to control the progression of the disease in a timely manner.
