Herpes sores are distinctive sores which break out in people who are infected with the herpes simplex virus (HSV). Not everyone with herpes will experience herpes sores, and people who do develop sores can experience outbreaks at random. Medications such as valacyclover, acyclovir, and famciclovir can be used to manage herpes infections and suppress outbreaks.
Several types of herpes virus can cause herpes sores to appear. HSV1 usually causes herpes sores above the waist, such as the distinctive cold sores or fever blisters experienced around the mouth, while HSV2 is primarily responsible for genital herpes. In both cases, the virus lurks in the body, periodically causing outbreaks when a patient is stressed, or in response to other environmental cues. An outbreak might occur once a month, every few months, or at totally random intervals.
People with herpes often experience tingling or burning sensations in the days before herpes sores appear. The site typically appears red, and then a painful blister emerges. The blister will break and scab over within a few days, and the herpes sore usually vanishes entirely within 10 days. Herpes sores tend to appear over and over in the same spot, which can lead to scarring.
When someone has sores, he or she is actively shedding the virus. People who have contact with herpes sores can contract herpes, and patients can also spread herpes to other areas of their bodies by handling sores and then handling other parts of their bodies. For example, someone who touches a herpes sore around the lip and then brushes an eye will develop herpes sores around the eyes in the future. However, people can also experience asymptomatic shedding, in which they can spread the virus even though no sores are present, so herpes sores should not be used to determine whether or not someone is infectious.
Herpes is a chronic infection which cannot be cured. Management of the disease can reduce the number of outbreaks and the amount of the virus shed, keeping the patient more comfortable. Individuals with herpes need to be very careful about contact with others to avoid spreading the disease, but people who have never experienced outbreaks should not assume that they are herpes free, as people can contract and carry the virus without developing sores. Screening at a doctor's office can determine whether or not someone has herpes, and screening for herpes and other sexually transmitted infections on a regular basis is strongly recommended for people who are sexually active.
