Shingles

Shingles (herpes zoster) is an itchy, painful rash with blisters. It is caused by the same virus as chickenpox (the varicella-zoster virus).

After recovering from chickenpox, the virus remains in the body. It retreats into a nerve ganglion near the spinal cord and can reactivate years later, causing shingles. Older people and people with a weakened immune system have a higher risk. Symptoms can last for weeks or even months.

For organisations with vital roles, international operations or an older workforce, it is important to take these risks seriously. Prevention and timely advice help to avoid disruption to work.

Where does shingles occur?

Shingles can be found on all continents. nyone who has had chickenpox can develop shingles later in life. The risk increases with age and reduced immunity.

Within organisations, employees aged fifty and over have a higher risk. Stress, illness or heavy physical or mental workload can trigger shingles.

What are the symptoms?

• Itching, tingling sensations or severe burning or stabbing pain
• Blisters in clusters on one side of the body
• Nerve pain (5-30%)
• Weakness of the face and hearing problems (rare)

How can you prevent shingles?

The fluid from shingles blisters is contagious. Therefore, it is important to avoid contact with the blisters. Wash your hands thoroughly after coming into contact with the fluid. If you have not had chickenpox, you can get chickenpox through contact with this fluid. If you have never had chickenpox, contact with this fluid can cause chickenpox. Good hygiene and timely reporting of symptoms help reduce the risk in the workplace.

Is vaccination against shingles possible?

Yes, vaccination against shingles is possible. The Dutch government is considering including the shingles vaccination in the National Immunisation Programme for people aged 60 and over, possibly from 2027. The vaccination consists of two doses, given a few months apart. Vaccination is especially relevant for employees aged fifty and over and for employees with an increased health risk.

If your employer has an agreement with us, you can book a vaccination appointment directly. If you wish to be vaccinated but your employer is not yet a client, your employer can contact us for an introductory meeting.
