A chickenpox rash has three stages of development: initial spots, fluid-filled blisters, and scabbed or crusted spots.
Chickenpox: A Complete Overview
This article will explain what chickenpox is, including information about its symptoms, risks, treatment, vaccination, and more.
Chickenpox is a disease caused by the varicella-zoster virus. Chickenpox is highly contagious and can spread from one person to another easily.
The most common symptom of chickenpox is the development of itchy blisters all over the body. However, not all cases of chickenpox present the same degree of symptoms.
Now that a vaccine is available, there is a

Some people have intentionally exposed their children to chickenpox to have them get the disease at that time and prevent more severe illness in adulthood.
However, the CDC strongly discourages this. Chickenpox at any age can cause very serious illness, severe complications, and even be fatal.
There is no guarantee that anyone, including a child, will experience mild symptoms, and the risk of complications remains. Additionally, while less likely, it is possible to be ill with chickenpox even after childhood or previous infection.
The best protection against chickenpox remains vaccination.
Symptoms can vary in intensity among individuals.
Some people experience a mild course of chickenpox. They develop only a small number of blisters and have few, if any, other symptoms. This is particularly true for those who get the infection despite having been vaccinated, which is uncommon but possible. Other people experience more extensive blistering and flu-like symptoms.
Adults may also experience more severe symptoms, having a high temperature for longer and developing more spots than children might.
A chickenpox rash typically develops fluid-filled blisters that can be very itchy. These blisters or lesions eventually turn into dry scabs.
The rash can appear anywhere, but it often appears first on the chest, back, stomach, pelvis, and face. The rash may then spread around the whole body. It can affect the skin inside the mouth, on the eyelids, or in the genital area.
Other symptoms can start before the onset of the rash and accompany the rash once it develops.
Chickenpox rashes can appear in three stages. However, new spots can develop while earlier spots move into the following stages. Therefore, it is possible to experience a rash exhibiting all three stages at once.
These stages include:
- Stage 1: Small spots that may resemble pimples develop. These spots can appear raised, flushed in color, red, or pink. The spots may also appear darker or similar in color to the surrounding skin. The spots may be more difficult to see on darker skin tones.
- Stage 2: The small spots develop into blisters or ulcers. Blisters fill with fluid and can cause the rash to itch. These blisters may burst and leak fluid. This fluid is contagious.
- Stage 3: The blisters dry out into scabs or crust over. Scabs can be flaky or still leak fluid.
Other common symptoms of chickenpox
These common symptoms of chickenpox can include:
- flu-like symptoms, such as fever, headache, and body aches
- malaise, general feeling of being ill
- respiratory symptoms, such as sneezing, runny or congested nose, sore throat, and cough
- loss of appetite
Serious symptoms that might indicate a life threatening condition
In some people, the varicella-zoster virus may spread to the brain or lungs.
Seek immediate medical care or call 911 for anyone experiencing symptoms including:
- a change in level of consciousness or alertness, such as passing out or unresponsiveness
- sudden changes in behavior, such as confusion, hallucinations, delusions, and delirium
- garbled or slurred speech, difficulty or inability to speak
- a fever of 101oF (38oC) or higher
- not producing any urine, or an infant who does not produce the usual amount of wet diapers
- respiratory or breathing problems
- severe dizziness or sudden loss of balance
- severe headache
- symptoms of meningitis
To make it easier to monitor changes to skin color on brown and black skin, check the soles of the feet, the palms, the insides of the eyelids, or the lips and tongue.
Below are some examples of what chickenpox rashes can look like at different stages.

Chickenpox is a highly contagious infection caused by the varicella-zoster virus.
Chickenpox is often contagious before the telltale blisters appear, and it can spread without direct contact. Therefore, it is difficult to avoid exposure to chickenpox. The CDC suggests that
Chickenpox can be spread directly through person-to-person contact and indirectly through the air. This happens as infectious droplets and aerosolized virus in coughs or sneezes pass through or remain in the air. A person who then breathes in, touches, or collects airborne viral particles on the mucous membranes may acquire the infection.
Additionally, close contact with people who have shingles
To lower your risk of developing chickenpox:
- avoid contact with people who have the disease or have had recent exposure to it
- get vaccinated against varicella-zoster virus with two doses
- get a chickenpox vaccine
within 3–5 days Trusted Source Centers for Disease Control and Prevention (CDC) Governmental authority Go to sourceafter exposure if you do not have immunity
- wash your hands well with soap and water after having contact with a person with chickenpox
There are two chickenpox vaccines available in the U.S., Varivax and ProQuad. Two doses of a vaccine can be effective, reducing the risk of hospitalization and death.
Contact your doctor to discuss vaccination.
Reducing the risk of transmitting chickenpox
- avoid scratching the rash or blisters to reduce contamination from the blister fluid
- keep your nails trimmed, and put mittens on infants’ and toddlers’ hands
- wash your hands well and regularly
- keep children with chickenpox home from school, day care, and away from others until all the spots have crusted over
- stay home from work and away from others until the spots have crusted over
For those who develop chickenpox, the goal of treatment is to relieve symptoms and prevent complications.
If you present symptoms of complications or secondary illness, your doctor will work with you to diagnose and treat them.
Follow your doctor’s instructions and take all medications exactly as prescribed. In addition, to
- apply anti-itch lotions, such as calamine
- avoid scratching the blisters and sores
- avoid sunlight and sunburn
- drink plenty of water
- take lukewarm oatmeal baths to soothe the skin
- take oral antihistamine medications
- take over-the-counter pain relief medications, such as acetaminophen (Tylenol) or ibuprofen (Advil, Motrin)
- wash your hands frequently
- wear clothes that are clean, dry, and loose fitting
It is important to remember that pain relief medication may not help alleviate fever. In addition, it is not safe to take too much pain reliever in a day. For example, you should not exceed 4 grams (g) of acetaminophen or 3.2 g of ibuprofen per day, especially if the medications do not help your symptoms.
Aspirin is not an appropriate medication for children.
Chickenpox can cause serious infections and further complications. People who are most at risk
- young infants
- pregnant people
- people with weakened immune systems
- people taking medications such as immunosuppressants or chemotherapy, or steroids long term
Additionally, pregnant people with weakened immune systems and people who are immunocompromised have a
Some older adults, including those who previously had chickenpox as a child, are also at risk of reinfection and more serious illness.
Rarely, the viral chickenpox infection can spread to other areas of the body, such as the brain or lungs, resulting in more severe illness and complications. In some people, these complications of chickenpox can be severe or even life threatening.
To minimize risk of serious complications, follow the treatment plan you and your doctor design.
- secondary infections of the blisters or sores
- severe dehydration
- cerebellar ataxia, brain inflammation resulting in loss of muscle coordination
- bleeding problems
- musculoskeletal conditions,

Here are questions people also ask about chickenpox. Elizabeth Thottacherry, M.D., an infectious disease and internal medicine clinician, provides answers.
Can you get chickenpox twice?
While it is possible, and in rare cases some people do experience repeat chickenpox infections, the risk of getting chickenpox more than once is generally very low. This is because most people develop and maintain immunity for the rest of their lives.
The virus that causes chickenpox can also reactivate and cause shingles.
How long is chickenpox contagious?
Chickenpox is contagious from about 48 hours before the rash appears until all of the rash blisters have crusted over.
However, this timeline is not exact for everyone, and there may be individual variation. Always take care with chickenpox around people at risk of complications.
Does chickenpox still exist in 2022?
Yes, chickenpox does still exist and infect people in 2022.
Is it better to get chickenpox or the vaccine?
It may be better to get the vaccine.
Chickenpox affects people differently, and there is no way to tell how serious an infection a person may get.
Vaccination gives you protection without the risk of a serious disease.
Is it possible to never get chickenpox?
It is possible to never have chickenpox, although this is unlikely, especially without vaccination, as chickenpox is a very transmissible disease.
However, if you have received the vaccine, it is possible that you may not contract chickenpox. You also may not have symptoms or have mild symptoms with a chickenpox infection.
Chickenpox is a highly contagious disease caused by the varicella-zoster virus. Although many people consider chickenpox to be normal in childhood, it can present significant risks of severe illness and life threatening complications.
Transmission of chickenpox can occur from contact with the rash or rash fluid, or through airborne viral particles. Vaccination is an effective way to reduce the risk of transmission and adverse impacts on health.
Contact your doctor for treatment, and seek emergency treatment for any serious symptoms. Your doctor can also help advise you about vaccination.
