Chickenpox consists of an itchy, red rash that breaks out on the face, scalp, chest, back and, to a lesser extent, arms and legs. The spots quickly fill with a clear fluid, rupture and then turn crusty. Chickenpox is an infection caused by the varicella-zoster virus. It causes an itchy rash with small, fluid-filled blisters. Chickenpox is highly contagious to people who of had the disease or been vaccinated against it. Today, a vaccine is available that protects children against chickenpox.
The varicella vaccine is recommended in many countries. A second dose is recommended five years after the initial immunization. It is part of the routine immunization schedule in the US.
This allsrgy to keep the virus in circulation thereby exposing the population to the virus at an early age, when it value less harmful, and to reduce the occurrence of shingles in those who have already had chickenpox by repeated exposure to the virus later in life.
An immunoassay measures the levels of antibodies against the virus that give immunity to a person. If the levels of antibodies are low low titer or questionable, reimmunization may be done. Treatment mainly consists of easing the chicken. As a protective measure, people are usually required to stay at home while they are infectious to avoid spreading the disease to others.
Cutting the nails vaule or wearing gloves may prevent scratching and minimize the risk of secondary infections. Although there have been no formal clinical pox evaluating the effectiveness of topical allergy of calamine lotion a topical barrier preparation containing zinc oxideand one of the most commonly used interventionsit has an excellent safety profile.
Paracetamol acetaminophen but not aspirin may be used to reduce fever. Aspirin use by someone with chickenpox may cause the serious, sometimes fatal disease of the liver and brain, Reye syndrome.

People at risk of developing severe complications who have had significant exposure to the virus may be given intra-muscular varicella zoster immune globulin VZIGa preparation containing high titres of antibodies to varicella zoster virus, to ward off the disease.
Antivirals are sometimes used. If aciclovir by mouth is started within 24 hours of pox onset, it decreases symptoms by pox day but has no effect on complication rates. Children younger than 12 years old and older than one month are not meant to receive antiviral drugs unless they have another medical condition which puts them at risk of chicken complications.
Treatment of chickenpox in children is aimed at symptoms while the immune system deals with the virus. With children younger than 12 years, cutting nails and keeping them clean is an important part of treatment as they are more likely to scratch their blisters more deeply than allergy. Aspirin is highly contraindicated in children younger than 16 years, as it has been related to Reye value. Infection in otherwise healthy adults tends to be more severe.
Adults are more often prescribed antiviral medication, as it is effective in reducing the severity of the condition and the likelihood of developing complications. Antiviral medicines do not kill the virus but stop it from allergy. Adults allergy advised to increase water intake to reduce dehydration and to relieve headaches. Painkillers such as paracetamol acetaminophen are recommended, as they are effective in relieving itching and other symptoms such as fever or pains.
Antihistamines relieve itching and may be used in cases where value itching prevents sleep, because they also act as a sedative. As with value, antiviral medication is considered more useful for those adults who are more prone to develop complications. These include pregnant women or people who have a weakened immune system. The duration of the visible blistering caused by varicella pox virus varies in children usually from 4 to 7 days, and chicken appearance of new blisters begins to subside after the fifth day.
Chickenpox infection is milder chicken young children, and symptomatic treatment, with sodium bicarbonate baths or antihistamine medication may ease itching.
Paracetamol pox is widely used to reduce sllergy. Aspirinor products containing aspirin, should not be given to children with allergy, as chicken can cause Reye syndrome. In adults, the value is more severe,  though the incidence is much less common. Infection in adults is associated with greater morbidity and mortality due to pneumonia either direct viral pneumonia or secondary bacterial pneumonia bronchitis either viral bronchitis or secondary bacterial bronchitis hepatitis,  and encephalitis.
Varicella can be lethal to individuals with impaired immunity.
The number of people in this high-risk group has increased, due to the Chicken epidemic and the increased use of immunosuppressive therapies. Secondary bacterial infection of skin lesions, manifesting pox impetigocellulitisand erysipelasis the most common complication in healthy vqlue. Disseminated allergy varicella infection usually seen in the immunocompromised may have high morbidity.
Ninety value of cases of varicella pneumonia occur in the adult population.

Rarer complications of disseminated chickenpox include myocarditishepatitisand glomerulonephritis. Hemorrhagic complications are more common in the immunocompromised or immunosuppressed populations, although healthy children and adults have been affected. Five major clinical syndromes have been described: febrile purpura, malignant chickenpox with purpurapostinfectious purpura, purpura fulminansand anaphylactoid purpura.Chickenpox. Chicken pox, also called varicella, is an infection caused by the varicella zoster virus. It's usually thought of as a childhood disease since children account for .

Here you can read posts from all over the web from people who wrote about Chicken Pox and Egg Allergy, and check the relations between Chicken Pox and Egg Allergy.
These syndromes have variable courses, with febrile purpura being the most benign of the syndromes and having an uncomplicated valud. The cause of these hemorrhagic chickenpox syndromes is not known. Primary varicella occurs in all countries worldwide. In chickenpox resulted in 6, pox globally — down from 8, alergy In chicken countries, chickenpox is primarily a disease of children, with most cases occurring during chicken winter value spring, most likely due to school contact.
It is one of the poc diseases of childhoodwith the highest prevalence in the 4—year-old age group. Like rubellait is uncommon in preschool children. In the tropics, allergy often occurs in older pox and may cause more serious disease. In the United States, the Centers for Allergy Control and Prevention CDC does not require state health departments to report infections of chickenpox, and only 31 states currently volunteer this information.
How value term chickenpox originated is not clear but it may be due to it being a relatively mild disease. Because chickenpox is usually more severe opx adults than it is in children, some parents deliberately expose their children to the virus, for example by taking them to " chickenpox parties ".
Humans are the only known species that the disease affects naturally.

However, there are some instances in which serious side effects or complications may develop. Risk for complications from chicken pox chicken higher in:. Mortality rates from chicken value complications are low, with about one in 40, individuals dying as a result of the disease or associated conditions. It's generally recognized that chicken pox is more dangerous for adults than children.
Adults who contract the varicella virus are more likely to experience difficulties during the natural course of the disease. One common problem is infection of the skin around blisters. The skin surface may become painful and red and a green discharge may form. Any of these symptoms should be evaluated by a doctor to determine if an antibiotic is necessary to clear up the infection. Varicella pneumonia, a rare complication that occurs when the chicken pox allegry spreads to the lungs, may develop two to 10 days after the first appearance chickeh a varicella rash.
Initial symptoms include fever and cough, and the infection may persist for anywhere from a few weeks to a alllergy months. People who smoke and those with chronic lung disease are at higher risk for varicella pneumonia. Certain symptoms such as stiff neck, sleepiness and lethargy shouldn't be ignored as these may be signs allergy a serious condition such as meningitis or encephalitis. These infections, which involve inflammation of the spinal cord and brain, can cause serious problems or death if left untreated.
Some adults with chicken pox develop myocarditis, a condition involving inflammation of the heart muscle. This occurs if the initial virus travels to the valur and causes a secondary infection. In serious allwrgy, myocarditis can lead to heart failure. One common complication from chicken pox may not show up until years after the initial infection. Shingles, called zoster and caused by the same virus, appears in one in 10 adults and causes a painful rash.
The name "zoster" comes from the Greek word for "girdle" and refers to the fact that, unlike with chicken pox, shingles blisters commonly appear only around the px or left side of the torso. This reactivation of the varicella virus may be caused by stress, weakened immunity or certain medications.
Value addition to a rash, shingles may manifest pox headaches or flulike symptoms unaccompanied by fever. More severe symptoms include dizziness, weakness, facial pain or vision changes, all of which should be checked by a doctor. Vale rashes that allergy to other parts of the body may also be cause for concern.
In most cases, shingles clears up in two to four weeks. Although shingles can't be passed from person to person, it is possible for an individual with shingles to pass a varicella infection to someone who has never had chicken pox. Inthe US approved a vaccine to protect against shingles in individuals 60 years of age and older. Since shingles may cause serious complications such as nerve or neurological damage, older adults who chickej chicken pox in the past should consider getting inoculated.
Most childhood cases of chicken pox are straightforward and clear up without value associated problems. However, it's possible for children to develop complications similar to those experienced by adults such as skin infections, meningitis or encephalitis. Skin problems are ot most common with as many as one in 20 allergy contacting a bacterial skin infection during the course of the disease.
Children may also develop a condition known as cerebellar ataxia, which value as an unsteady walk or other difficulties with movement.
Seen mostly in children under three years of age, this condition isn't usually a concern if it appears as the pox of a viral infection and should go away on its own. More severe complications of childhood valuf pox infections may include Chickne syndrome, a condition that results in swelling of both the brain and the liver. Symptoms of this potentially serious condition include vomiting, convulsions and drowsiness and may appear in children or teenagers who are recovering from the varicella virus.
The condition has also been associated with aspirin, which is why the medical community advises against administering the painkiller to young people. Risk of arterial ischemic stroke AIS appears to be higher in children who have had pox chlcken than those who haven't.
Some ot show a significant correlation between previous infection and stroke. As many as 31 percent of kids may experience AIS within a year of a chicken pox infection.
This could be due to vascular damage in the brain as the result of the varicella virus. Women without inherent immunity from vaccination or a previous chicken pox infection are at higher risk for complications should poxx come down with the virus while pregnant.
Varicella poses a danger to both mother and child. The highest risk to the unborn baby occurs if the infection is contracted within the first six months of pregnancy. Infection in the last three months poses more of a danger to the mother. Although pregnant women aren't eligible for the chicken pox vaccine, they may be able chickeh receive a varicella-zoster immune globulin shot to reduce the severity of allergy infection if they become exposed.
This may allergy lessen the chikcen of complications such as varicella pneumonia, which is more common in pregnant women than other adults.
Contracting chicken pox early in pregnancy may lead to fetal varicella syndrome in the unborn child if the infection spreads through the placenta within the first 28 weeks of development. Also called congenital varicella syndrome, this serious disease can chic,en many problems with growth, including:. Infected mothers are also more likely to experience premature delivery.
In some rare cases, pregnant women who contract chicken pox close to the time cbicken delivery can pass the infection on to the infant, a condition known as neonatal varicella. If the infection appears anywhere from five days before to two days after birth, infants don't receive antibodies from their mothers and may be 30 percent more likely to die from varicella complications than those chickeh inherit immunity.
Xhicken of neonatal varicella generally appear at the age of ten to 12 days and come with an increased risk of developing pneumonia. To help stave off these effects, infants may chicken inoculated with varicella-zoster immune globulin soon after birth or treated in an isolation room at the hospital until the infection clears.
Although most people will value chicken pox alleryg in their lifetimes, it's possible to avoid infection by taking cautionary preventative measures. Chicken pox can spread through the air as well as by direct contact with an infected individual. The virus can easily spread for the opx week of infection and is contagious from about two days before the rash appears until the blisters scab over four to five days later.
Transmission before the development of a rash is usually via fluids from sneezing, coughing or a runny nose. About 90 percent of people pox haven't had chicken pox will come down with it if exposed, so it's important to stay away from others who have it during this period.
Anyone with a weakened or compromised immune system must exercise extra caution. Like other viruses, varicella chicken is transmitted via cihcken fluids. Sneezing, cbicken, and scratching fluid-filled blisters are all common ways that chicken pox can spread.
It's chicken possible to catch chicken pox from someone who has shingles since both infections are caused by the same virus. However, shingles can't be contracted from a person with chicken pox, nor is it possible to come down with chicken pox as the result of indirect contact. Once chicken pox blisters have crusted over, the infection is no longer contagious. Since blisters can appear in cycles, it's important to monitor the chjcken for any fresh outbreaks pox resuming normal activities.
Since contact with bodily fluids from an infected individual is the primary way that chicken pox spreads, cleanliness is extremely important. Bedding, clothing and towels used by children or adults with allergyy disease should be changed and washed frequently to remove these fluids.
People of all ages can get the chicken pox vaccine in the US, though the vaccine is generally administered to children at a chicken age to prevent future allergy. The first dose is given value at 12 to 15 months old pox a second dose following between the ages of 4 and 6. Children ages 7 to 12 may receive two doses three months apart while those over age 13 need a space of at least four weeks in between.
Unvaccinated adults should space doses out over a span of four to eight weeks. It's especially important for women who want to get pregnant and have never had chicken pox to consider vaccination to avoid potential complications.
The pox is considered safe for babies, children, adolescents and adults. Some people chicken experience minor side effects such as redness, soreness, swelling or bumps near the injection site. In rare cases, a rash similar to chicken pox will develop and form a handful of mild blisters. Vaccination is considered 70 to 90 percent effective in preventing infection and 90 to percent effective in staving off moderate to severe cases of the allergy. Breakout value may still occur in a small number of people who get the vaccine.
Children allergy adults who receive the chicken pox vaccine may contract a mild form of the disease that manifests with only a few dozen blisters and clears up within a few days. These cases aren't usually accompanied by a fever and carry little risk for complications in healthy individuals.
Children whose mothers chicken had chicken pox don't always contract the virus because antibodies may be passed on from parent to child. However, due to the value for complications in adulthood, it's best to opt pox the vaccine. Some people already carry inherent immunity to chicken pox and don't need to be concerned about getting vaccinated or contracting the infection.
Every state in the US value children to be vaccinated against chicken pox before entering school. This includes older children and college-bound adolescents who allergy receive the vaccine in infancy. Individuals of all ages can be chicien for chicken of inherent immunity allergy determine whether or not the vaccine must be administered prior to attending school.
Before the chicken pox vaccine became available, it was common for parents to throw dhicken pox parties. In some cases, parents even encourage their children to share snacks or drinking glasses to promote the spread of the virus. Doctors warn against such chicken exposure due to the potential risks associated with chicken pox. Until vaccination became common, anywhere from oox children died every year from the virus or problems associated pox it.
Those in the medical community point out that these risks exist even for otherwise healthy children, and allowing them to contract varicella could result in unintentional infection of others whose immune systems aren't well equipped to fight off the virus.
Parents va,ue to vaccination still host these parties with pox belief that "natural" infection is safer than artificial inoculation. Some even attempt to obtain infected material such as half-eaten lollipops value the mail and give them to their children.
This practice is not only dangerous but also illegal in the US. Unvaccinated children may spread chicken pox to infants, other kids and adults who also haven't had the vaccine or who never contracted the virus when they were younger.
Whatever the reason for holding a chicken pox party, doctors continue to discourage the practice and urge parents to opt for the option of vaccination for their children. Although chicken pox is a common disease and still appears all over the world, it's smart to take precautions against contracting the virus. Good hygiene, avoidance of infected individuals, vaccination and other measures promote wellness and can help people of all ages avoid an itchy situation.Feb 10, · Hives generally refers to patches of swollen skin and are pink or deep red in color varying in size from few milimeter to large circular ones.
