Herpes is a viral infection and there is a possibility that it will heal on its own, without medication, but it is not recommended to go without medication. The purpose of treatment with medication is to shorten the course of the disease and reduce the spread of the disease and complications. Herpes simplex heals itself in about 2 weeks, chickenpox can heal in 1-2 weeks, healing takes 2-3 weeks in younger patients with shingles, and may take 3-4 weeks or longer in older people. Although herpes is self-healing, herpes virus infection, if not actively treated, can easily lead to a series of sequelae, such as herpes zoster can cause posterior neuralgia, chickenpox can cause pneumonia, herpes simplex can recur, etc. For people with low immunity, such as children and the elderly, it can be life-threatening in severe cases, so it is generally advisable for patients to undergo early standardized treatment. For patients with herpes, patients should be given drugs such as valacyclovir or famciclovir in a timely manner, which can effectively inhibit the replication of the virus. For example, in patients with herpes zoster, antiviral medications given within 72 hours can reduce nerve damage and decrease the chances of posterior neuralgia compared to no medication treatment. After developing herpes, patients should promote healing after resting, keeping the skin of the lesion clean, eating easily digestible food, and adequately hydrating.
