Shingles, herpes zoster, is a very contagious and painful rash, or blister that appears on the skin. These rashes most commonly appear on the sides of the body in stripes. The stripes are made up of many very painful blisters caused by a certain type of virus. The varicella zoster, most commonly known as the chicken pox virus attacks the nerve roots in that area. The herpes zoster virus is in the herpes family, including HSV, herpes simple virus, which causes cold sores, fever blisters, and genital herpes. (WebMD, 2011) Most people are required to get the chicken pox shot when they are children although some do not. The chicken pox shot helps to keep out the virus by keeping it dormant in the nerves. The varicella zoster virus stays in a
If you have had chickenpox during your childhood, it is sure that the virus has stayed in your system for numerous of years. But the virus has then been reactivated in later life, and that’s what causes the skin disease called “Shingles,” to develop. As well as chickenpox, there are other diseases which weakens our immune system. For example, HIV and/or AIDS can also cause Shingles to develop. Shingles is not considered a life threatening virus, but can become quite painful. Shingles is an extraordinarily painful condition that involves inflammation of sensory nerves.
Starting from the beginning; Varicella or chicken pox is an infectious disease that can be characterized by an itchy skin rash. The rash usually appears a few days after exposure and can spread throughout the entire body accompanied with fever, fatigue, and flu like symptoms. Each rash blister will dry out and form a scab which then falls off in the course of healing. Getting chicken pox more than
This article addresses Shingles also known as herpes zoster which originates from the virus that also causes chicken pox. The burden of this disease is that it causes severe pain and rash with a blistering. According to this article there is an increased risk of a stroke or heart attack within the first week of your diagnosis.
Herpes zoster goes back a long time but scientists were unable to tell the difference between the blistering caused by small pox, and shingles until now. Where shingles started was first talked about in 1831, when Richard Bright, a scientist, believed the dorsal root ganglion, or the spinal ganglion was what carried the disease. In the late 18th century William Heberden found a way to differentiate between shingles and small pox, and then in the late 19th century shingles was differentiated from another disease called erysipelas. In the beginning of the 20th century it was the first time scientists realized that the same virus was causing chickenpox and shingles. Shingles was thought to be not dangerous in the 1940s and harmful side effects were thought to be scarce. When 1942 hit scientists started to recognize that when adults got shingles it was more dangerous than when a child had it, and the harmful effects of shingles increased as you got older. More studies in the 1950s on people with the shingles virus showed that scientists were wrong about the virus being harmless, and so they started looking for ways to prevent the virus. In 1965 Dr. Hope-Simpson was first to suggest that contact with children who had chicken pox would boost the cells immunity to help postpone or suppress shingles. An experimental drug called Zostavax was created to fight against shingles in 2005. The drug was later FDA approved in 2006, it is too early to tell if the drug works,
Shingles, otherwise known as herpes zoster, is a painful skin rash that occurs on one side of the face or body. The risk of getting shingles increases with age. Shingles vaccines, which are recommended for those 50 and older, can prevent the painful disease.
Shingles is caused by a reactivation of the varicella zoster virus, or VZV—the same virus that causes chickenpox. After recovery from chickenpox, some VZV particles can settle in nerve cells where they remain inactive or hidden for many years. They can be reactivated during adulthood, and spread down the long the nerve fibers, called axons, that extend from the sensory cell bodies to the skin. The mechanism of how the virus is reactivated is unknown, however, it is related to old age and weak immune system. As the matter of fact, shingles is more common in older
Shingles is a very painful and often a very harmful condition. This virus is generated by the same virus (herpes zoster) none as chickenpox’s. After one gets chickenpox, the virus can lie inactive in the sensory nerves for at least 20 years. It reappears when the disease fighting system is weakened by age, disease or unmanaged stress. When events happen that decrease the disease fighting system, such as getting older, extreme emotional stress, extreme illness, or long-term usage of drugs, the disease fighting system cannot hold down and stop the inactive organisms any longer and they become active again, causing infection along the pathway of the nerve. Shingles is a very painful disease that affects the immune system; however,
Shingles is a skin disease that causes large rashes and blisters. The shingles virus normally comes after you have had the chicken pox. Once you have gotten the chicken pox the shingles virus is already inside of you. This doesn’t exactly mean that you will get shingles if you have had the chicken pox it just means you are more likely to get it. The correct name of the virus that gives shingles is varicella zoster virus this virus is the same for chicken pox. The shingle virus can stay dormant inside of someone for years but when it comes awake it will travel up nerves and whatever those nerves control is what will be affected. According to (The british skin foundation) “About 20% of people who have had chickenpox will have an attack of shingles
Chickenpox’s history has various contributors. Several corpses have been found with chickenpox as the apparent cause of death. In the 1500s, an Italian physician Giovanni Filippo gave the first description of varicella in literature and clearly distinguished it from scarlet fever; he is also known for other several important contributions to medicine, anatomy, and virology. In the late 1600s, English physician Richard Morton gave the name chickenpox to what he thought was a milder form of smallpox. Another English physician, William Heberden, undertook the first independent study of the disease in 1767, and he proved that chickenpox was actually different from smallpox. Since then much more information has been learned about chickenpox.
Shingles is a viral infection, caused by the Varicella-Zoster virus. This is the same virus that affects you when you have chicken pox. Varicella-Zoster is not the same virus that causes cold sores or genital herpes, this would be the HSV1, or HSV2 (herpes simplex virus.) HSV1 is associated with cold sores, HSV2 is associated with genital herpes. However, once you have had chicken pox, the virus lays dormant, so later in life the virus can become active. Activated later in life the virus becomes shingles. This virus lays dormant in the nerve tissue close to the brain and spinal cord. Once the virus is activated, it is a very painful virus, that takes weeks or months for the virus to run it’s course.
What are vaccines exactly? A vaccine is a substance used to arouse the assembly of antibodies and provide immunity against diseases. How do these vaccines work? When a disease germ enters the body, it is an antigen that makes a person sick. If this same germ enters
The infectious outbreak I chose to research is the varicella-zoster virus, which causes varicella better known as chickenpox. The number of chickenpox cases can be decreased or can be decreased in severity by having two doses of the zoster vaccine. “Before the vaccine, about 4 million people would get chickenpox each year in the United States. Also, about 10,600 people were hospitalized and 100 to 150 died each year as a result of chickenpox.” ("Chickenpox (Varicella)")
Before vaccines were introduced, varicella was endemic in the United States, and virtually all persons acquired varicella at some point before adulthood (cdc.gov, 2006). It is reported that 4 million cases of chickenpox were recorded in the U.S. each year before the vaccine was introduced. Although some states reported cases of varicella to the CDC, it was eliminated from the list of nationally notifiable conditions in 1981. Children under 10 years of age make up between 75 – 90 % of chickenpox cases. In 1995, due to the availability of the vaccine in the U.S., hospitalizations due to chickenpox has declined by nearly 90% (Hambleton, & Gershon, 2005).
Chickenpox is a viral infection caused by the Varicella Zoster Virus (VZV) transmitted via the respiratory route that causes itchy, blisters-like rashes usually lasting about 5-10 days. It is highly contagious transmitted by person to person contact (direct) from respiratory secretions or indirectly through contact with airborne respiratory droplets, via soiled inanimate objects infected by discharge from skin lesions, vesicle discharges or nasopharyngeal secretions. The incubation period lasts about 10-21 days and the disease is communicable 1-2 days
