Your Answer: When you get the chicken pox, sometimes it totally resolves, but in some cases it lays dormant in the nerve cells. When it is reactivated as shingles it can manifest it self in may ways. It usually appears along nerve endings. Which makes it very painful. You can not get the shingles if you have not had the chicken pox. Nor can you get the chicken pox from a person who has shingles. It is important not to go around pregnant women during the time you have shingles. You can also have shingles more than once. Chapter 19 Correct answer: Chicken pox and shingles are different manifestations of infection with varicella-zoster virus, a type of herpesvirus. Chicken pox is most often a childhood disease beginning as a respiratory infection and then spreading throughout various tissues of the body. The infection eventually manifests in cells of the dermis, developing into a characteristic rash and "teardrops on rose petals" lesions. After the infection subsides, the virus can become latent in nerve ganglia and remain there for decades. Upon reactivation, which happens in about 20% of adults who had chicken pox as children, the virus travels back down the nerves and causes the characteristic lesions of shingles. These lesions involve a painful rash that is limited to particular bands of skin innervated by the infected nerve. Individuals who have never had chicken pox therefore cannot contract shingles, although they can contract chicken pox from a shingles patient. Chicken pox is typically much more severe in adults than in children because of the more highly developed immune response in adults. Quiz Score: 30 out of 30 [Show More]
