Herpes zoster is not exclusive to the elderly, but is now reported clinically from time to time in children with shingles. Herpes zoster is commonly known as “waist-waist”, which describes a disease that occurs on the waist and only on one side of the body, and the concept that a rash around the waist can be life-threatening in the elderly is, of course, unscientific. So what is shingles? In fact, the pathogen of the goods are not unfamiliar, it and chickenpox is actually the same ancestor, namely “chickenpox – herpes zoster virus”, people infected with this virus, the initial susceptibility to “chickenpox”, after the goods are secretly latent, latent in which? Where is it lurking? Lurking in the posterior spinal nerve roots or spinal neurons. Once the time is ripe, this guy will come out to cause trouble, so the formation of a common clinical skin disease – shingles. The typical rash of herpes zoster, as the name implies, is blisters, and is clustered, and another is that the distribution of the rash is band-shaped, and only on one side of a part of the body, that is, not more than the midline of the body, and a very important feature on the pain, older people pain is obvious, affecting sleep, younger people pain is not obvious, and sometimes accompanied by itching, the reason for the pain, because The reason for the pain is that the “varicella zoster virus” is very unfaithful, it will invade the local nerves, causing nerve degeneration or necrosis, so the pain appears. The other thing that must be emphasized is the contagiousness, in general the disease is not contagious to the general population, but in general to some unusual people such as infants, children, pregnant women or contagious, so if an elderly person has shingles, do not let her or him help with the children, the elderly is hard enough, the key is to infect the little baby ah. The other is pregnant women, pregnant women are a delicate group, so with shingles, please stay away from pregnant women, because once a pregnant woman has shingles, not only is the pregnant woman suffering, the key is the possibility of negative impact on the fetus, such as miscarriage ah, stillbirth ah, developmental deformities ah.
