Chickenpox in Children – All That You Should Know


Chickenpox or Varicella Zoster is a virus that usually strikes children. It is identified by red and itchy blisters or bumps that appear in different parts of the body. Normally, individuals experience chickenpox only once in their lifetime.

Who is at risk from chickenpox? 

Chickenpox is usually experienced in childhood. It is mild and rarely has any complications. Once a child is infected with chickenpox, he or she develops immunity to it, so hardly ever would an individual experience it again. However, it can be severe among adults.

Those at greater risk of serious complications from chickenpox include people whose immune systems have been weakened by illnesses like HIV and cancer or strong treatments such as chemotherapy; pregnant women as it can affect the foetus if she catches chickenpox. It can lead to serious birth defects and severe chickenpox in the baby at birth.

Chickenpox in Children – All That You Should Know

How does chickenpox spread?

Infected people can spread the disease to those who have never had it. It is carried in the air when an infected person coughs or sneezes, or if he touches chickenpox blisters or inhales the virus particles that are present in the blisters.

Must know Chickenpox Symptoms

If your body has a rash of red blisters, it means you have chickenpox. Symptoms usually appear any time between the first and three weeks after infection sets in. This is the incubation period.

Early symptoms: It’s not unusual for symptoms to start showing up within a day or two, after which the rash becomes visible. These early symptoms are:

  • General exhaustion and illness
  • Fever with 100.4 degrees Fahrenheit
  • Headache
  • Sore and aching muscles
  • Loss of appetite

These symptoms are not universally experienced, but are common among adults and older children.

Let’s take a look at the symptoms of chickenpox that everyone experiences. They are:

  1. Chickenpox rash: Chickenpox rash develops in three chief stages:
  • Spots:Chickenpox rash begins to show up as small red spots, slightly raised off the skin.At first, these spots are seen on the face and chest, after which it spreads to different body parts. There could be very few spots all over the body or there could be numerous that cover the entire body. Spots are also seen at times on the palms, soles inside the mouth and ears and near the genitals or around them.
  • Blisters: In the hours after thered rash shows up or the next day, the spots will rise to develop a blister filled with fluid. Though the blisters may be very itchy, yet one shouldn’t scratch them as scratching them could only spread the infection to other parts of the body and increase the risk of complications, making it a more serious skin disease.
  • Scabs and crusts:Within the next few days, the fluid in the blisters turn misty and the blisters dry out and a scab forms over the blisters. After the rash begins, it’s easy to find new spots, so there may come a time when you see new spots, blisters and scabs around the same body parts. Once you have chickenpox, it’s easy to spread it to others until all the blisters have scabs. This normally takes about a week after the rash begins. After this period, the crusty scabs will fall off and you will be relieved of this disease within the next two weeks.
  1. More serious and rarer chickenpox symptoms: Usually, healthy people make a quick and complete recovery, if they just rest as much as possible and drink lots of liquids. However, there are those patients of chickenpox who suffer more severe symptoms than usual.

You know that your symptoms are serious if you have these symptoms. In such a case, get in touch with your doctor immediately.

  • You see red and painful skin surrounding the spots and/or blisters
  • You have respiratory problems

Chickenpox vaccine

One sure way of preventing contracting this disease is to take the chickenpox vaccine in childhood as this alone protects one against the Varicella Zoster virus. There are two chickenpox vaccines one can take–Varivax and Varilrix.

Who should take the chickenpox vaccine? The chickenpox vaccine should be given to those who are in contact with people with weakened immunity. This helps reduce the chances of infecting others. If one is going to start working in a radiotherapy department and has not had chickenpox before, it would help him to take the vaccine.

Dosage for chicken pox vaccination: Usually, two doses of this vaccine gives 98% effectiveness against the disease.

For infants, children and adults: For children below 13 years old, two doses of the vaccine should be given, one between 12-15 months of age; and second, between the ages of 4 years-6 years.

Children about 13 years of age or older who have never had chickenpox or taken the vaccine, should get take two doses with a gap of 28 days.

Pregnant women should postpone the vaccine until after delivering the baby. Once they take the vaccine, they should not get pregnant for a month.

How the chickenpox vaccine works: This is a live vaccine, which contains a small dose of the weakened virus that causes chickenpox.Once injected, it encourages the immune system to produce the required number of antibodies to protect individuals against chickenpox.

How does a healthcare provider give the chickenpox vaccine? The vaccine is given in two parts in the upper arm with a gap of four to eight weeks.

Is the chickenpox vaccine effective?Nine out of 10 children who are vaccinated once develop enough immunity against chickenpox. However, two doses are recommended for best results.

Side-Effects of Chickenpox Vaccine:

  • Sore arm after the vaccination
  • Pain and stiffness in the joints
  • Fever
  • Mild rash

It’s very rare that anyone taking the chickenpox vaccine has serious side-effects. However, those that have experienced side-effects report having experienced extreme body rash, liver or lung infection, pneumonia, seizures and meningitis.


Chicken pox is treatable, and preventable too. If you do find you have the symptoms, consult your doctor immediately.
