Snakebite, also commonly known as shingles, is caused by varicella-zoster virus infection and is contagious, especially in immunocompromised infants, young children and the elderly who are susceptible to infection. Initial infection with the varicella-zoster virus may manifest as chickenpox or an occult infection. The virus enters the body and can incubate in the posterior spinal ganglia. With low immunity, the virus can be reactivated and cause shingles. Patients mainly present with zonal clusters of blisters with neuralgia distributed along the nerves on one side of the body. Careful skin management is recommended to maintain blister integrity and avoid infection. Until the rash blisters have healed, it is recommended to avoid close contact with other people, especially pregnant women, infants, people who have not had chickenpox, and the elderly, to avoid transmission. Skin blisters with neuralgia, it is recommended to go to the dermatology department of the hospital in a timely manner, after a clear diagnosis, under the guidance of the doctor to give standardized treatment.
