**Shingles (Herpes Zoster): What You Need to Know**

Shingles is a painful viral infection caused by the varicella-zoster virus, the same virus responsible for chickenpox. After recovering from chickenpox, the virus remains dormant in nerve cells and can reactivate years later, often due to a weakened immune system, stress, or illness.

### Who’s at Risk?
Shingles mainly affects those who’ve had chickenpox before, especially:
– People over 50
– Individuals with weakened immune systems (e.g., cancer, HIV, organ transplants)
– Those experiencing stress, trauma, or illness

### Symptoms
Early signs include fever, chills, headache, fatigue, and light sensitivity. Within days, a painful rash develops, followed by redness, blisters, and severe discomfort.

### Complications
Shingles can lead to post-herpetic neuralgia, bacterial infections, nerve damage, or even spread to vital organs in rare cases.

### Prevention & Treatment
The **Shingrix** vaccine significantly reduces the risk of shingles and complications. While there’s no cure, **antiviral medications** (Acyclovir, Famciclovir, Valacyclovir) can speed recovery if taken early. Pain relievers like **paracetamol or ibuprofen** help manage discomfort. **Antibiotics** may be needed for secondary infections.

### Is Shingles Contagious?
While shingles itself isn’t contagious, the varicella-zoster virus can spread to those who’ve never had chickenpox, causing them to develop chickenpox instead. To prevent transmission:
– Keep the rash covered
– Wash hands frequently
– Avoid contact with infants, pregnant women, and immunocompromised individuals

Seek medical advice if you suspect shingles.
