The duration of an attack after exposure to the shingles virus varies from person to person, about 14 days for chickenpox, and the duration of a shingles attack is related to the body’s immunity. The shingles virus is known as varicella-zoster virus. Primary infection manifests itself as chickenpox and is most common in children, with an incubation period of about 14 days. Infection can be prevented by vaccination with the attenuated varicella vaccine, or by using medications such as acyclovir to shorten the course of the disease. After chickenpox is cured, there are still viruses latent in nerve cells. When the resistance of the body decreases, such as trauma, fatigue, malignant tumors, and the use of immunosuppressant drugs such as leflunomide, cyclosporine, tacrolimus, etc., the viruses are activated and manifested as herpes zoster, and the time of its onset can not be determined. Antiviral therapy can be administered with drugs such as acyclovir and bromovudine. If necessary, it is recommended to go to the hospital in time for examination and use the drugs under the guidance of the doctor.
