Yes, you can get chickenpox from someone who has shingles, but only if you have never had chickenpox and have not been vaccinated against it. The same virus causes both conditions. When a person has shingles, the active virus can spread and cause chickenpox in someone who is not immune. Direct contact with the shingles rash is what spreads the virus, not breathing the air near the person.
Can You Get The Chickenpox From Shingles?
The short answer is yes. The varicella-zoster virus causes both chickenpox and shingles. After a person recovers from chickenpox, the virus stays dormant in nerve tissue. Years later, it can reactivate and cause shingles. During a shingles outbreak, the virus is active in the skin rash. If someone who has never had chickenpox touches that rash, they can catch the virus and develop chickenpox.
This is not the same as catching shingles itself. A person who gets the virus from a shingles rash will develop chickenpox, not shingles. Shingles only happens when the dormant virus reactivates in someone who already had chickenpox.
How The Virus Spreads From Shingles To Chickenpox
The virus lives in the fluid inside the shingles blisters. When the blisters break, the fluid contains live virus. Direct skin-to-skin contact with that fluid is the main way the virus spreads. The virus does not travel through the air from a person with shingles the way it does when someone with chickenpox coughs or sneezes.
However, if the shingles rash is in an area not covered by clothing, the virus could potentially spread through the air. This is less common but possible. The risk is highest when the rash is on exposed skin and the blisters are weeping.
A person with shingles is contagious from the time the blisters appear until the rash crusts over completely. This usually takes about 7 to 10 days. Once the blisters have scabbed, the person is no longer contagious.
Who Is At Risk Of Catching Chickenpox From Shingles
Only people who have never had chickenpox and have not received the chickenpox vaccine can catch the virus from a shingles rash. This includes:
- Infants who are too young to be vaccinated
- People who never had chickenpox as children
- People who did not receive the varicella vaccine
- People with weakened immune systems who may not have full protection from past infection or vaccination
Most adults in the United States had chickenpox as children. The vaccine was introduced in 1995, so adults born before that time likely had the natural infection. If you had chickenpox in the past, you are immune and cannot catch it again from a shingles rash. Your body already has antibodies that recognize and fight the virus.
Pregnant women who have never had chickenpox face a specific risk. Catching chickenpox during pregnancy can cause serious complications for both the mother and the baby. If you are pregnant and have been exposed to shingles, contact your obstetrician promptly.
Chickenpox Vs Shingles: Key Differences
Chickenpox and shingles are caused by the same virus but present very differently. Understanding the difference helps clarify why the virus spreads the way it does.
| Characteristic | Chickenpox | Shingles |
|---|---|---|
| Who gets it | People who have never had the virus | People who already had chickenpox |
| Rash location | Widespread, covering much of the body | Localized, usually one side of the body |
| Rash pattern | Hundreds of small blisters | A strip or band of blisters along a nerve path |
| How it spreads | Through the air and direct contact | Direct contact with the rash fluid |
| Can it recur | Almost never after first infection | Yes, in some people |
The chickenpox rash typically spreads across the entire body and can include hundreds of blisters. The shingles rash stays confined to one area. It follows a single nerve pathway and usually appears on the torso, face, or one side of the body.
How Long Is Someone With Shingles Contagious
A person with shingles is contagious only while the rash is active. The contagious period begins when blisters first appear and ends when the blisters have dried and crusted over. This process typically takes 7 to 10 days.
During this time, the person should keep the rash covered with loose clothing or a bandage. They should avoid touching the rash and wash their hands frequently. This is especially important if they are around people who have never had chickenpox.
People with shingles do not need to be isolated from others who have already had chickenpox. Those individuals are immune and cannot catch the virus again. The main concern is protecting people who are not immune.
Can Shingles Be Prevented
Yes. The shingles vaccine is recommended for adults aged 50 and older. The vaccine reduces the risk of getting shingles and also reduces the risk of long-term nerve pain if shingles does occur.
The Centers for Disease Control and Prevention recommends two doses of the recombinant shingles vaccine for adults 50 and older. This vaccine is highly effective. It is also recommended for adults 19 and older who have weakened immune systems.
Even if you already had shingles, you can still receive the vaccine. Having shingles once does not guarantee you will not get it again. The vaccine provides additional protection.
For people who have never had chickenpox, the chickenpox vaccine is the best protection. Two doses of the varicella vaccine provide strong immunity. This vaccine is part of the standard childhood immunization schedule in the United States.
What To Do If You Were Exposed To Shingles
If you have never had chickenpox or the vaccine, and you touched someone’s shingles rash, contact a healthcare provider. They may recommend the chickenpox vaccine if given within 3 to 5 days of exposure. Early vaccination can prevent the disease or reduce its severity.
For people who cannot receive the vaccine, such as pregnant women or those with weakened immune systems, a doctor may prescribe antiviral medication. This is called post-exposure prophylaxis. It can help prevent chickenpox from developing after exposure.
If you develop a rash, fever, or flu-like symptoms within 10 to 21 days after exposure, see a doctor. These could be early signs of chickenpox. Early treatment can reduce the severity of the illness.
Do not visit a doctor’s office without calling first. Chickenpox is highly contagious to people who are not immune. The office may have special protocols to prevent spreading the virus to other patients.
Treating Chickenpox Caught From Shingles
Chickenpox in healthy children is usually mild and resolves on its own. Treatment focuses on relieving symptoms. Antihistamines can reduce itching. Calamine lotion and oatmeal baths also help. Acetaminophen can manage fever and discomfort.
Do not give aspirin to children or teenagers with chickenpox. Aspirin use during a viral illness has been linked to Reye’s syndrome, a rare but serious condition that causes swelling in the liver and brain.
In adults, chickenpox tends to be more severe. Adults are at higher risk of complications such as pneumonia. Antiviral medications may be prescribed for adults, pregnant women, and people with weakened immune systems. These medications work best when started within 24 hours of the rash appearing.
When To See A Doctor
See a doctor if you or your child develop chickenpox and any of the following occur:
- Fever lasting more than 4 days
- Fever above 103°F
- Rash that becomes very red, warm, or tender
- Difficulty breathing
- Severe headache or confusion
- Stiff neck
- Difficulty waking up
These symptoms may indicate a bacterial infection of the skin or other complications. Prompt medical evaluation is important.
Anyone who is pregnant, has a weakened immune system, or has a newborn baby should contact a doctor at the first sign of exposure or symptoms. These groups face higher risks from chickenpox.
Frequently Asked Questions
Can you get shingles from someone with chickenpox?
No. You cannot catch shingles from someone with chickenpox. Shingles only develops when the dormant virus inside a person who already had chickenpox reactivates.
How long does it take for chickenpox to appear after shingles exposure?
Symptoms typically appear 10 to 21 days after exposure to the virus. The rash usually develops 1 to 2 days after fever and other symptoms begin.
Can you get chickenpox from shingles if you were vaccinated?
It is very unlikely. The chickenpox vaccine provides strong protection against the virus. Some vaccinated people can still get chickenpox, but the illness is usually mild with fewer blisters and a faster recovery.
Is it safe to be around someone with shingles if you had chickenpox as a child?
Yes. If you had chickenpox in the past, you are immune and cannot catch the virus again from a shingles rash. Your immune system already has antibodies that protect you.
