Oral and labial herpes and genital herpes are mostly caused by herpes simplex virus infections, while shingles is caused by varicella zoster virus. Generally viral infections are prone to infect patients with low immunity. These viral infections are followed by the use of antiviral medications, including ribavirin, acyclovir, and ganciclovir, which can be taken orally or intravenously, as well as topical ointments. Viral infections generally have a long course of treatment, usually taking about 2-4 weeks to gradually improve. To prevent these herpes virus infections, it is important to eat a well-balanced diet, exercise, have a regular routine, stop smoking, stop drinking, and improve your immune system. In addition, if you have chronic bacterial or fungal infections, it is important to treat them in a timely manner, as they can be easily combined with viral infections.
