An introduction to the varicella zoster virus known as chickenpox

Ninety percent of cases of varicella pneumonia occur in the adult population. Five major clinical syndromes have been described: After a day or two, the fluid in the blisters gets cloudy and they begin to dry out and crust over. The fluid can also be "cultured", whereby attempts are made to grow the virus from a fluid sample.


This may be the result of: These early symptoms can include: A high temperature is particularly uncommon. Rarer complications of disseminated chickenpox include myocarditishepatitisand glomerulonephritis.

New blisters may appear for up to a week, but a few days after appearing they become yellowish in colour, flatten and dry out. The first dose is given around age 1 and the second around ages In children, the first symptom of chickenpox is usually an itchy rash that appears on the head and spreads down to the trunk and other body parts.

These deaths and hospital admissions have substantially declined in the US due to vaccination, [19] [20] though the rate of shingles infection has increased as adults are less exposed to infected children which would otherwise help protect against shingles.

Like all enveloped virusesit is sensitive to desiccation, heat and detergents. As with children, antiviral medication is considered more useful for those adults who are more prone to develop complications. It is available as a single vaccine, and it is also available as part of the MMRV vaccine measles, mumps, rubella, and varicella vaccine.

If you still develop shingles after having this vaccine, it may be milder and last for a shorter time than usual. Don't share any cloths, towels or flannels if you have the shingles rash. Aspirinor products containing aspirin, should not be given to children with chickenpox, as it can cause Reye's Syndrome.

Five major clinical syndromes have been described: They can advise about whether you should continue breastfeeding your baby. These include infections of the brain encephalitisthe protective membranes around the brain meningitis or part of the brain called the cerebellum cerebellitis.

The most common complication is where the blisters become infected with bacteria. Care for chickenpox usually includes use of pain medications and topical treatments for the itchy rash, blisters, and scabs. Chickenpox infection is milder in young children, and symptomatic treatment, with sodium bicarbonate baths or antihistamine medication may ease itching.

The fluid can also be "cultured", whereby attempts are made to grow the virus from a fluid sample. Reactivation of VZV results in the clinically distinct syndrome of herpes zoster i.

Other complications in children Very rarely, chickenpox can lead to more serious complications involving the nervous system brain and spinal cord in children.

Cell-mediated immune responses are also important in limiting the scope and the duration of primary varicella infection. However, the risk of getting shingles from vaccine-strain VZV after chickenpox vaccination is much lower than getting shingles after natural infection with wild-type VZV.

The blisters crust over and disappear within about days. If you have had chickenpox in the past, it is extremely unlikely that you will develop chickenpox for a second time.


It is essential to seek medical advice so that you can receive any necessary treatment.Chickenpox, also known as varicella, is a highly contagious disease caused by the initial infection with varicella zoster virus (VZV). The disease results in a characteristic skin rash that forms small, itchy blisters, which eventually scab over.

[1]. INTRODUCTION. Varicella-zoster virus (VZV) infection causes two clinically distinct diseases. Primary infection with VZV results in varicella, also known as chickenpox, characterized by vesicular lesions in different stages of development concentrated on the face and trunk, and less so on the extremities.

Shingles is caused by the varicella zoster virus (VZV), the same virus that causes chickenpox.

Varicella vaccine

After a person recovers from chickenpox, the virus stays dormant (inactive) in the body. Scientists aren’t sure why the virus can reactivate years later, causing shingles. Cause and Symptoms. Chickenpox is an illness caused by the Varicella zoster virus.

It was once an almost universal childhood experience. Now it is much less common in the United States owing to widespread vaccination. Jun 28,  · Shingles, also known as herpes zoster, is an infection of a nerve and the skin around it.

It's caused by the varicella-zoster virus, which also causes chickenpox. Varicella 22 Varicella is an acute infectious disease caused by varicella zoster virus (VZV). The recurrent infection (herpes zoster, also known as shingles) has been recognized since ancient.
