Main Characteristics
- Chickenpox is caused by the varicella zoster virus and is highly contagious.
- The main symptom includes an itchy rash with fluid-filled blisters.
- Vaccination is the most effective preventive measure.
General Overview
Chickenpox, a contagious disease affecting individuals of all age groups, usually presents with mild symptoms that resolve without complications.
Information on chickenpox provided on this page is suitable for adults and children above the age of 5.
Recognizing Symptoms
Chickenpox manifests primarily as an itchy red rash, accompanied by other symptoms like fever, headache, and malaise. The duration of the illness ranges from 10 days to 3 weeks, with children being more susceptible than adults.
The rash typically starts as small, red spots and progresses into fluid-filled blisters.
Exclusion Periods for Common Childhood Illnesses
It is important to note that children with chickenpox should be excluded from school or daycare until all blisters have dried and crusted over, usually about 5-7 days after the rash first appears. This is to prevent the spread of the virus to other children who may not have had chickenpox before.
Parents should also be aware that chickenpox is highly contagious, especially in the early stages when the rash is still developing. It is recommended to keep the child isolated from others to prevent further transmission.
Proper hygiene practices, such as frequent hand washing and avoiding close contact with individuals who are at high risk for complications from chickenpox, are essential in controlling the spread of the virus.
Preventive Measures
Chickenpox transmission occurs through cough droplets and contact with blisters. Infected individuals should remain at home until the blisters crust over.
Seek Medical Assistance
Contact a healthcare provider if chickenpox is suspected, especially in cases of severe symptoms or high fever. Note that chickenpox is a notifiable disease in Australia.
It is important to seek medical assistance promptly to receive proper treatment and prevent the spread of the virus to others. Your healthcare provider may recommend antiviral medications to help alleviate symptoms and shorten the duration of the illness. Additionally, they may provide guidance on how to care for the skin lesions and relieve itching.
Special Considerations
Chickenpox can be perilous for pregnant women, infants, and immunocompromised individuals. Seek medical advice if exposed.
Severe Complications in Pregnant Women
Avoid chickenpox during pregnancy and consider pre-conception immune screening to mitigate risks.
Protecting Infants

Infants are at higher risk for severe complications from chickenpox. Ensure they are kept away from anyone infected and seek medical attention if they show any symptoms.
Immunocompromised Individuals
People with weakened immune systems are more susceptible to severe chickenpox complications. Consult with a healthcare provider to discuss preventive measures.
Vaccination Recommendations
Vaccination is the most effective way to prevent chickenpox. Make sure you and your family members are up to date on vaccinations to reduce the risk of infection.
Diagnosis and Treatment
Chickenpox diagnosis involves physical examination, reviewing contact history with infected persons, and, in some cases, fluid tests.
Common symptoms of chickenpox include fever, rash, and blisters. The rash typically starts on the chest and back and then spreads to other parts of the body. It is important to seek medical attention if you suspect you or your child has chickenpox, as complications can arise, especially in adults.
Treatment for chickenpox usually involves managing symptoms, such as itching and fever, and preventing the spread of the virus to others. This may include taking antiviral medications, using calamine lotion to reduce itching, and practicing good hygiene to prevent the virus from spreading.
Management and Prevention
Currently, there is no specific treatment for chickenpox. Symptoms can be managed using rest, hydration, and medications to alleviate itching and fever.
To prevent the spread of chickenpox, it is important to ensure that individuals who are infected stay at home until all of the blisters have crusted over. It is also recommended to practice good hand hygiene and avoid close contact with anyone who has chickenpox.
For individuals who have not had chickenpox, vaccination is available as a preventive measure. The chickenpox vaccine is safe and highly effective in preventing the disease or reducing the severity of symptoms if contracted.
Vaccination Recommendations
Prevent chickenpox through vaccination, which is safe and endorsed, particularly for high-risk groups. Children are eligible for free vaccines under the National Immunisation Program.
Important Vaccination Guidelines
Vaccination is advised for those who have never had chickenpox or the vaccine, with exceptions for pregnant women or individuals with weakened immune systems.
Workers in childcare, aged care, or healthcare sectors are strongly encouraged to get vaccinated due to their heightened exposure risk.
Potential Complications
Though rare, complications can occur, such as skin infections and lung inflammation. Antibiotics may be prescribed for infected blisters.

The red and pink spots are visible on the skin, with the surrounding area also turning pink.
A child with light-brown skin has over 40 red or pink spots covering their chest in the initial stage of chickenpox. Some spots are forming blisters, while others remain flat.
In another case of stage 1 chickenpox, there are fewer than 50 spots, all less than 1cm in size. The larger spots are pink, while the smaller ones blend with the skin tone. Some spots are raised, indicating blister formation, while others are flat.
As the blisters fill with fluid, they become very itchy and may eventually burst, progressing to stage 2 chickenpox.
The emergence of blisters, spots, and scabs characterizes stage 3 of chickenpox. These symptoms are visible on different skin tones and vary in size.
It is essential to avoid contact with vulnerable groups when infected with chickenpox, such as newborns, pregnant individuals, or those with weakened immune systems.
If uncertain about the condition, it is advisable to follow self-treatment measures at home and seek medical advice if symptoms worsen suddenly or specific complications arise.
Chickenpox transmission can occur from a few days before visible spots appear until all scabs have formed, typically within a week of onset.
To prevent the spread of chickenpox, vaccination is recommended for individuals at risk, available through NHS or private clinics at a cost.
