Chickenpox

Chickenpox is a highly contagious viral infection caused by the varicella zoster virus (VZV), a type of herpes virus. The disease mainly occurs in children, but adults can also develop chickenpox. In adults, the disease often has a more severe course and may lead to complications.

For organisations with internationally travelling employees or employees who work in teams, chickenpox is a relevant health risk. Infection can lead to sickness absence and disruption of work activities.

Where does chickenpox occur?

Chickenpox occurs worldwide. In many countries, people contract the disease at a young age, but this is not the case everywhere. Employees who grew up in countries where chickenpox is less common may still become infected later in life.

Do your employees travel abroad for work or work in international teams? If so, it is important to know whether they are protected against chickenpox.

What are the symptoms?

• Skin rash with fluid-filled blisters starting on the head and trunk, spreading over the body
• Fever
• General malaise
• Bacterial infections like sepsis, pneumonia, and meningitis
• Later reactivation: shingles

How can you prevent chickenpox?

Chickenpox is highly contagious and can already be transmitted before symptoms become visible. Preventing infection is therefore difficult. Vaccinations are available to prevent chickenpox. In many countries, chickenpox vaccination is part of the routine vaccination programme for young children. This is not the case in the Netherlands, but it is included on Bonaire, St Eustatius and Saba. The vaccination must be administered twice for optimal protection.
