Transcript of Chickenpox.
"Chicken pox." World of Scientific Discovery. Gale, 2007. Gale Student Resources In Context. Web. 18 Apr. 2012. Symptoms: The time between exposure of the virus and the appearance of symptoms may be long, but the chickenpox usually starts with only a mild fever. However, as the virus progresses, red spots appear on the body that become "vesicles." Vesicles are itchy, fluid-filled bumps that stay on the body for about two to five days and can arise anywhere, including inside the mouth, nose, ears, vagina, and rectum. Some people may have very few of these vesicles, while others have two to five hundred. Sometimes hyperpigmentation occurs around some of these vesicles, which is a temporary darkening of the skin, but towards the end of the virus' progression, the vesicles typically form scabs and fall off. Also, these vesicles usually only leave scars if they've been scratched too much. The degree of itchiness of them varies among infected people; some infected people may even experience headachces and abdominal pain while others don't. Sources: "Chicken pox."

Prognosis The chickenpox typically only lasts for two to five days and the average mortality rate for all ages is about 9 out of 100,000 people who acquire the virus. Chickenpox does not usually result in a poor quality of life because the body can easily fight it; however, 1 out of every 3,000 teenagers or adults may acquire encephalitis, which is the swelling of the brain due to infections and can lead to paralysis, seizures, loss of consciousness, or even death. Sources: Campos, M.D., Abelardo J. C. "Varicella Zoster Virus (VZV)." Johns Hopkins Medicine. Web. 26 Apr. 2012. <http://www.hopkinsmedicine.org/heic/ID/vzv/>. Reemerging Infectious Disease: The Varicella Zoster infection is a re-emerging infectious disease. This means that the infection may continue to "evolve." Natural genetic variations, recombinations, and adaptations may contribute to this evolution and can therefore allow new strains of known pathogens to appear that the immune system cannot recognize. Treatment: As of March 1995, a vaccine for the chickenpox was approved to be distributed in the U.S. This vaccine is still being distributed to children all around the world, reducing the number of chicken pox cases from 4 million to only 400,000 yearly. The chicken pox vaccine is considered a "live" vaccine, which means it contains live varicella zoster virus in order to provide a way for the body to know how to fight the virus in case of later infection. Furthermore, due to this vaccine, the varicella zoster virus is not particularly common in any one area of the world, but among a particular demographic of the population. Such as children or the elderly whose immune systems are not as strong. Sources: "Chicken pox." World of Scientific Discovery. Gale, 2007. Gale Student Resources In Context. Web. 29 Apr. 2012. Diagnosis/Treatment: Doctors usually diagnose chickenpox based on the lesions on the skin. However, chickenpox can also be confirmed with blood tests or a culture of the lesion samples. The treatment for chickenpox is just to keep the infected person clean and comfortable during the course of the infection, which may last up to two weeks. Doing this may involve using topical medications and cold compresses to prevent itching because scratching the vesicles can cause scarring or infections. Some examples of medications are antihistamines or an antiviral drug such as acyclovir (Zoivrax), which may be used to shorten the course or severity of the infection. Sources: "Chicken pox."
