what does chicken pox look like ?

Question

and how long does it take to heal?
what is the best form of treatment for it too?
an also how contagious is it?

Answer 1

Starts out as little red bumps, starting usually on the tummy, finally covering the body. The bumps become raised and fluid filled. The sores will cover the body from head to toe, including genitals. They will eventually heal and form a scab. Chicken pox causes severe itching, but scratching should be avoided, as this can lead to secondary infection.

Treatment consists of keeping patient comfy as possible. Give benadryl, tylenol if there's a fever, and use calamine lotion to soothe the skin. Your doctor can prescribe other meds in severe cases, but it usually just has to run its course.

It is no longer contagious after all the sores have scabbed over and the patient has no more oozing sores. However, it is very contagious during the active period.

Answer 3

Chicken pox looks like characteristic blisters, containing water like substance in them. They may look red on a fair person and dark on a dark skinned person. They start appearing on the body, head and limbs of a person who is affrected with the virus causing it. It can last two to three weeks normally, but can go more than this if the person is affected severely. There are modern medicines to treat this. Usually paracetamol is given to reduce the fever. Chickenpox is highly contagious. It spreads from person to person by direct contact or through the air from an infected person's coughing or sneezing. Touching the fluid from a chickenpox blister can also spread the disease. A person with chickenpox is contagious from 1-2 days before the rash appears until all blisters have formed scabs.

Picture Note the pustules and excoriation due to scratching. Red around the lesions, especially if hot, may suggest secondary infection

Chicken pox is a highly infectious disease caused by the varicella-zoster virus. It is a DNA virus of the family human herpes virus.

Epidemiology: Although immunisation against chicken pox has been routine in the USA since 1995, it is not practiced in the UK and most children are liable to develop the disease at some stage during childhood. Spread throughout households is very common with infection of up to 90% of vulnerable individuals who come into contact. Most infection occurs under 5 years old and immunity increases with age until adulthood.1 It tends to occur in sporadic outbreaks, usually in winter or spring.
It is not a notifiable disease but current trends in incidence for England and Wales can be found at the website of the Birmingham Research Unit of the RCGP2 and north of the border through Health Protection Scotland.3
Infectivity is from a few days before the onset of the lesions until the crusts fall off. It is not possible to catch shingles from chicken pox as the former represents a resurgence of a dormant virus. It may be possible to catch chicken pox from active lesions of shingles but in practice this is rare.

Risk factors: Usually it is a self limiting disease but complications can occur, especially in the immunocompromised, including steroid therapy4 and malignancy. It tends to be milder in younger children than in older children and if contracted in adulthood it is significantly more unpleasant. It is dangerous in neonates and to the fetus if contracted in pregnancy. The infection tends to be severe in pregnancy with a high risk of pneumonia as well as risks to the fetus as described below. Complications may occur in as many as 1 in 50 cases.

Presentation:

* The virus enters through the upper respiratory tract. Viraemia occurs 4 to 6 days later but the incubation period between exposure and the first skin lesions is around 10 to 14 days but can be as long as 21 days.
* The first feature is often pyrexia. A temperature of around 38 to 39ºC is usual for up to 4 days. Infection with chicken pox and subsequent immunity can occur without clinical disease. Headache, malaise and abdominal pain may be reported.
* Crops of vesicles appear over the course of 3 to 5 days. They are mostly on the head, neck and trunk and very sparse on the limbs.
* The lesions tend to be very itchy but perhaps less so in younger children. They pass through the stages of papule, vesicle, pustule and crust.
* When the crusts fall off they may leave marks that may be present for a few weeks but there is normally no long term residue. However, in adolescents and adults there is a greater risk of scarring.
* Redness around the lesion may suggest bacterial superinfection, probably introduced by scratching.
* Lesions may occur in the oropharynx. Little girls may get vulval lesions that are very unpleasant.
* Prolonged eruptions or delayed crusting may suggest impaired cell mediated immunity.

nvestigations: Usually the diagnosis is obvious on clinical grounds, especially during in epidemic. Confirmation can be obtained by taking a scraping of a lesion and using immunohistochemical staining.
Complications require further investigation. Respiratory symptoms require CXR and neurological features demand lumbar puncture.

Differential diagnosis: The clusters of vesicles usually makes the diagnosis clear.

* Vesicles can occur in many skin diseases are super infection often itchy. Examples include dermatitis herpetiformis, impetigo, other viral skin infections, contact dermatitis and Stevens-Johnson syndrome but usually the clinical picture is obvious.
* Shingles or herpes zoster is like varicella but confined to just one dermatome. There may also be malaise.
* The lesions of chicken pox are at different stages and appear in clusters, tending to be central in distribution. The lesions of smallpox are all at the same stage and tend to be more peripheral. Smallpox has been eradicated and there is no known animal vector but the virus is kept in about a dozen laboratories throughout the world. In theory it could be developed for biological warfare or terrorism.

Management:

* Usually the disease is left to run its course but treatment may be given to reduce pruritis. Calamine lotion can be given ad lib but as it dries it ceases to be effective. Sedative antihistamines may be helpful. The newer, non-sedating drugs are not helpful as the effect is related to the sedative properties rather than antihistamine effect. They may relieve distress, improve sleep and reduce the risk of scratching causing secondary infection or scarring. Nails should be kept short.
* Antipyretics like paracetamol or ibuprofen can be used. Aspirin must be avoided in children up to 12 and possibly a little beyond as there is a risk of Reye's syndrome in association with chicken pox.
* Secondary infection may require antibiotics.
* In those who are very ill, immunocompromised or at special risk, antivirals like aciclovir can be used. The usual dose for adults is 800mg, 5 times a day for 7 days. For the dose in children refer to the BNF. If immunoglobulin is offered there is advice from the Health Protection Agency in The Immunoglobulin Handbook5, in which chicken pox is chapter 7.

Complications:

* Secondary infection of lesions, probably from scratching occurs in 5 to 10% and are usually indolent. Secondary bacterial infections, especially group A streptococcal, can produce necrotizing fasciitis and toxic shock syndrome.
* Viral pneumonia can be life-threatening. It occurs most often in older children and adults, appearing 3 or 4 days after the onset of the rash. Chest pain wheezing and tachypnoea are all signs.
* Encephalitis is a serious illness that may require admission to an ICU. Symptoms include confusion, irritability, drowsiness and vomiting. Weakness or inability to walk, severe headache and neck stiffness are also possible features. Encephalitis occurs in 1.7 per 100,000 cases of varicella among otherwise healthy children between 1 and 14 years. The mortality rate is 5 to 20%.
* If caught in the first 20 weeks of pregnancy there is a 2% risk of congenital varicella syndrome.6 This causes a range of problems including intrauterine growth retardation, microcephaly, cortical atrophy, limb hypoplasia, microphthalmia, cataracts, chorioretinitis, and cutaneous scarring. Infection with varicella in the later stages of pregnancy can cause premature delivery or neonatal chickenpox infection. This is particularly serious if the mother becomes infected 7 days before birth. There is no such risk with shingles. If chicken pox appears in a pregnant woman she is offered immunoglobulin. There is no correlation between the severity of the chicken pox and the risk of fetal involvement.
* About 5% of children get otitis media

Neonatal varicella: If chicken pox is caught in late pregnancy it can cause premature delivery. If the rash appears within a week of delivery or within 2 days after delivery, there is risk of neonatal varicella. There is transplacental transmission of virus but not antibody as there is no time for IgG to develop and the baby is at 30% risk of death from severe pneumonia or fulminant hepatitis. Treatment is with immunoglobulin and aciclovir. If at least a week passes between the rash and delivery then maternal IgG should give adequate protection. The initial antibody response is IgM but this does not cross the placenta.
Intrauterine infection after 20 weeks gestation can result in neonatal herpes zoster. This usually presents in the first year of life and most commonly involves a thoracic dermatome.

Prevention: There are no plans to make immunisation against chicken pox routine for British children. A vaccine is available and it is offered to healthcare workers who may come into contact with the disease whilst not immune. This appears to represent about 10% of the adult population. Two doses of vaccine are given 4 to 8 weeks apart and seroconversion is not routinely assessed. More information about the vaccine is available on the HPA website at www.hpa.org.uk. The immunocompromised, including those on steroids and being treated for cancer are at risk especially children with leukaemia who may have a mortality of 7%. The response to vaccine is remarkably good7 but immunoglobulin can still be used.
Those who have had the disease are usually immune but second and even third attacks are reported, especially if the first was mild.

If you have chickenpox! just scratch but you'll not get rid of the itch, you'll just have loads of little chicken pox scars!
