What is Chickenpox?
Chickenpox is a highly contagious viral disease caused by the varicella-zoster virus (VZV), a member of the herpes virus family. It is characterized by an itchy, blister-like rash that appears on the skin and can spread throughout the body. The disease is most common in children under the age of 10, but it can affect people of all ages who have not been vaccinated or have not had the disease before.

Definition and Overview
Chickenpox typically begins with a mild fever, headache, and fatigue, followed by the appearance of the characteristic rash. The rash starts as small, red bumps that quickly develop into fluid-filled blisters. These blisters eventually burst, crust over, and form scabs that fall off within a few weeks. The rash can be very itchy and may appear on the face, scalp, chest, back, and limbs.
In most cases, chickenpox is a mild illness that resolves on its own within a week or two. However, in some cases, complications can occur, especially in infants, adolescents, adults, and people with weakened immune systems. These complications can include bacterial infections of the skin, pneumonia, and encephalitis (inflammation of the brain).
History of Chickenpox
Chickenpox has been a common childhood illness for centuries. Before the development of the varicella vaccine in 1995, almost everyone in the United States contracted chickenpox at some point in their lives, usually during childhood. In fact, about 4 million people in the U.S. got chickenpox each year, resulting in over 10,000 hospitalizations and 100 to 150 deaths.
Since the introduction of the varicella vaccine, the incidence of chickenpox has decreased dramatically. The vaccine is highly effective at preventing the disease, and most people who receive the recommended two doses will not get chickenpox. Those who do get chickenpox despite being vaccinated usually have a milder form of the illness with fewer blisters and a faster recovery time.
Despite the availability of the vaccine, chickenpox remains a concern, particularly for those who cannot be vaccinated due to medical reasons or who have weakened immune systems. It is important for individuals to be aware of the signs and symptoms of chickenpox and to take steps to prevent its spread, such as staying home from work or school until the blisters have crusted over.
Causes of Chickenpox
Chickenpox is caused by the varicella-zoster virus (VZV), a highly contagious member of the herpes virus family. This virus is responsible for the characteristic itchy, blister-like rash that appears on the skin and can spread throughout the body.
Varicella-Zoster Virus
The varicella-zoster virus is the sole cause of chickenpox. Once a person is infected with VZV, the virus remains dormant in the body’s nerve cells after the initial infection has resolved. In some cases, the virus may reactivate later in life, causing a condition called shingles (herpes zoster).
Transmission Methods
Chickenpox is highly contagious and can spread easily from person to person through various transmission methods:
- Direct contact: Chickenpox can be transmitted by directly touching the blisters, saliva, or mucus of an infected person.
- Airborne transmission: The virus can also spread through the air when an infected person coughs or sneezes, releasing tiny droplets containing the virus.
- Indirect contact: Chickenpox can be spread indirectly by touching contaminated items that have been freshly soiled, such as clothing, from an infected person.
- Shingles exposure: Direct contact with the blisters of a person with shingles can cause chickenpox in someone who has never had the disease and has not been vaccinated. However, once the blisters have dried and crusted over, they are no longer capable of spreading the virus.
The risk of transmission is highest from one to two days before the rash appears until all the blisters have dried and crusted over, which usually takes about four to seven days after the onset of the rash. People with weakened immune systems may be contagious for a longer period.
Symptoms and Diagnosis
The symptoms of chickenpox typically appear 10 to 21 days after exposure to the varicella-zoster virus. The illness begins with a mild fever, headache, loss of appetite, and tiredness, followed by the development of the characteristic itchy rash.
Early Signs
One to two days before the rash appears, individuals may experience the following symptoms:
- Fever
- Tiredness
- Loss of appetite
- Headache
The classic sign of chickenpox is a rash that turns into itchy, fluid-filled blisters which eventually become scabs. The rash may first appear on the chest, back, and face, and then spread over the entire body, including inside the mouth, eyelids, or genital area. It usually takes about one week for all blisters to become scabs.
In vaccinated people, the symptoms of chickenpox may be milder, with fewer or no blisters, mild or no fever, and a shorter duration of illness compared to unvaccinated individuals. However, some vaccinated people may still experience symptoms similar to those who are unvaccinated.
Diagnosis Methods
Healthcare providers can often diagnose chickenpox based on the appearance of the rash and other symptoms. Laboratory tests, including blood tests or tissue studies of affected skin samples, can also confirm the diagnosis.
Polymerase chain reaction (PCR) is the most useful laboratory test for confirming suspected varicella and herpes zoster. PCR can rapidly and sensitively detect VZV DNA in skin lesions, such as vesicles, scabs, or maculopapular lesions. Vesicular lesions or scabs are the best specimens for sampling, while other sources like nasopharyngeal secretions, saliva, urine, bronchial washings, and cerebrospinal fluid are less likely to provide an adequate sample and may lead to false-negative results.
Other viral isolation techniques, such as direct fluorescent antibody assay (DFA) and viral culture, are generally not recommended due to their lower sensitivity compared to PCR and longer turnaround times.
Serologic methods have limited use for laboratory confirmation of herpes zoster and should only be used when suitable specimens for PCR testing are not available. IgM serologic testing is considerably less sensitive than PCR testing of skin lesions and cannot distinguish between primary infection, reinfection, or reactivation from latency.
Complications of Chickenpox
While chickenpox is usually a mild disease, it can lead to serious complications, especially in certain high-risk groups. These complications can range from bacterial infections of the skin to more severe conditions affecting the lungs, brain, and other organs.

Common Complications
Some of the most common complications associated with chickenpox include:
- Bacterial infections of the skin and soft tissues, particularly Group A streptococcal infections
- Pneumonia (infection of the lungs)
- Encephalitis or cerebellar ataxia (infection or swelling of the brain)
- Hemorrhagic complications (bleeding problems)
- Sepsis (bloodstream infections)
- Dehydration
In some cases, these complications can be severe enough to require hospitalization. However, thanks to the widespread use of the chickenpox vaccine in the United States, hospitalizations and deaths due to chickenpox complications have become rare.
Severe Cases
Certain individuals are at a higher risk of experiencing severe complications from chickenpox. These include:
- Infants
- Adolescents
- Adults
- Pregnant women
- People with weakened immune systems, such as those with HIV/AIDS, cancer, or those who have undergone transplants or are receiving chemotherapy, immunosuppressive medications, or long-term steroid treatment
In the past, many healthy adults who died from chickenpox contracted the disease from their unvaccinated children. Today, while deaths from chickenpox are rare, they still occur in healthy, unvaccinated children and adults.
It is crucial for individuals who are at high risk of complications to take precautions to avoid exposure to the virus and to seek prompt medical attention if they suspect they have contracted chickenpox. Vaccination remains the most effective way to prevent chickenpox and its potential complications.
Treatment Options
The treatment of chickenpox primarily focuses on managing symptoms and preventing complications. While there is no specific cure for the virus, several options are available to help alleviate discomfort and promote recovery.
Medications for Symptom Relief
Over-the-counter medications can be used to relieve symptoms associated with chickenpox:
- Acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) can help reduce fever and alleviate pain. However, aspirin should be avoided in children due to the risk of Reye’s syndrome.
- Antihistamines, such as diphenhydramine (Benadryl), can help relieve itching. Calamine lotion or cool compresses applied to the skin can also provide relief from itching.
- Antiviral creams or ointments, such as docosanol (Abreva), may be used to soothe the skin and promote healing of the blisters.
It is essential to follow the dosage instructions carefully and consult with a healthcare provider before administering any medications, especially to children.
Antiviral Treatments
In some cases, antiviral medications may be prescribed to help reduce the severity and duration of chickenpox symptoms, particularly in high-risk individuals or those with severe infections. These medications work by inhibiting the replication of the varicella-zoster virus.
The most common antiviral medications used for treating chickenpox include:
- Acyclovir (Zovirax)
These medications are most effective when started within the first 24 hours of the rash appearing. They are usually administered orally in pill form, but in severe cases, intravenous (IV) administration may be necessary.
Antiviral treatment is typically recommended for:
- Adults and adolescents
- People with weakened immune systems
- Pregnant women
- Newborns whose mothers developed chickenpox shortly before or after delivery
- Individuals with severe symptoms or complications
It is crucial to consult with a healthcare provider to determine if antiviral treatment is appropriate and to discuss the potential benefits and risks.
In addition to medications, it is important to maintain good hygiene practices to prevent the spread of the virus and to avoid scratching the blisters, which can lead to secondary bacterial infections. Keeping the skin clean, wearing loose, comfortable clothing, and getting plenty of rest can also aid in the recovery process.
Home Remedies and Care
While there is no cure for chickenpox, several home remedies can help alleviate symptoms and provide relief during the healing process. These remedies focus on reducing itchiness, soothing the skin, and managing fever and pain.
Soothing Skin Treatments
To soothe the itchy and irritated skin caused by chickenpox, consider the following treatments:
- Apply calamine lotion to the sores to help reduce itching.
- Take baking soda or oatmeal baths to soothe the skin. Oatmeal contains anti-inflammatory compounds called beta glucans that may help reduce inflammation and itching.
- Use cold compresses wrapped in a towel to provide relief from itching.
- Apply cooled chamomile tea or add chamomile flowers to a bath, as chamomile has anti-inflammatory and antibacterial properties.
- Take oral antihistamines, such as diphenhydramine (Benadryl), to help manage itching symptoms.
- Distract yourself or your child with engaging activities to resist the urge to scratch the sores.
Preventing itching is crucial to avoid complications, such as open sores that may bleed or develop secondary infections. To minimize scratching:
- Keep fingernails short to prevent creating cuts in the skin.
- Put clean socks on the hands at night to avoid scratching while sleeping.
- Wear loose-fitting clothing made from natural fibers, like cotton.
- Pat the body dry with a clean towel after bathing, rather than rubbing the skin.
- Avoid exertion or becoming too hot or sweaty, as this may irritate the sores.
For fever and pain management, use over-the-counter medications such as acetaminophen, following the dosage instructions on the package or as directed by a doctor or pharmacist. Children’s versions of these medications are available for younger patients.

Dos and Don’ts at Home
When caring for someone with chickenpox at home, keep these dos and don’ts in mind:
- DO wash your hands regularly and wash bed linens and recently worn clothes with hot, soapy water.
- DO rest, but allow quiet activity.
- DO use non-aspirin drugs for fever.
- DO notify school nurses and parents of playmates who may have been exposed.
- DO call your healthcare provider if your temperature is higher than 101°F, or if weakness, headache, or sensitivity to light develop.
- DO call your healthcare provider if vomiting, restlessness, and irritability occur, with decreased consciousness.
- DON’T scratch blisters or scabs.
- DON’T expose pregnant women, newborns, elderly people, or those with low resistance to infection to chickenpox.
- DON’T let infected children go to school or daycare for at least 6 days after the first blisters appear. Dried, crusted scabs are not infectious.
- DON’T give aspirin to children younger than 16 years because of the risk of Reye’s syndrome.
For mouth sores, sucking on popsicles or ice cubes may help reduce itchiness and pain. Sipping or swishing chamomile tea in the mouth may also help reduce inflammation.
Remember, if you or your child are at high risk for complications or develop severe symptoms, contact your healthcare provider for guidance and possible antiviral medication.
