Chickenpox in Adults: Why Infection Can Be More Serious Later in Life

Can Adults Get Chickenpox?

Yes. Although chickenpox is commonly thought of as a childhood illness, adults can still develop the infection if they have never had chickenpox before and have not been vaccinated. Many people assume they must have had chickenpox as a child, but this is not always the case — and some adults remain susceptible to infection without realising it.

This often becomes apparent when they are exposed to chickenpox through their own children, family members, schools, nurseries or workplaces.

Why Is Chickenpox Often Worse in Adults?

One of the most important things adults should know is that chickenpox is generally more severe in adulthood than in childhood. While many children experience a relatively mild illness, adults are more likely to feel significantly unwell and are at greater risk of complications.

The exact reasons are not fully understood, but healthcare professionals have long recognised that age increases the likelihood of severe symptoms and more serious outcomes. This is why chickenpox infection in adults is taken particularly seriously.

What Are the Symptoms of Adult Chickenpox?

Adults typically experience the same symptoms as children, but these symptoms are often more pronounced. Many adults report feeling unwell for several days before the rash appears, and recovery may take longer than it typically does in younger children.

What Complications Can Occur?

Most adults recover fully from chickenpox, but complications are more common than they are in childhood. While serious complications remain uncommon, the increased risk compared with children is important to understand — particularly if symptoms suggest pneumonia or more serious illness is developing.

Medical advice should be sought if an adult develops chickenpox, particularly if breathing becomes difficult or symptoms appear unusually severe.

Chickenpox and Pregnancy

Chickenpox during pregnancy requires particular attention. Infection can occasionally cause complications for the mother and, in certain circumstances, may also affect the developing baby.

Who Should Consider Their Chickenpox Immunity?

Many adults never think about chickenpox until they are exposed to the virus. However, understanding whether you are immune can be particularly important in certain circumstances.

• People who work in healthcare
• People who work with children
• Those who are planning a pregnancy
• Parents of children attending nursery or school
• Those who live with someone who has a weakened immune system
• Anyone who knows they have never had chickenpox

For these individuals, understanding their level of protection may help them make informed decisions about prevention.

Can Adults Be Vaccinated Against Chickenpox?

Yes. Adults who have never had chickenpox may be eligible for vaccination. The chickenpox vaccine helps the immune system develop protection against the virus without the risks associated with natural infection.

• Adults who know they have never had chickenpox
• Individuals planning a pregnancy in the future
• Healthcare workers seeking protection
• Those who wish to reduce their personal risk of infection

A healthcare professional can help determine whether vaccination may be appropriate based on your medical history and circumstances.

What to Do Next

Although chickenpox is often associated with childhood, adults can still develop the infection and are more likely to experience severe symptoms and complications. Understanding your immunity status and considering your personal risk factors can help you make informed decisions about your health.
