What is Chickenpox?

Chickenpox is a contagious viral infection caused by the varicella-zoster virus. It typically presents with an itchy vesicular rash, fever, and fatigue. While often mild in children, it can be more serious in adults or those with weakened immunity.

In India, vaccination is available and may reduce risk. Please consult a healthcare professional for guidance on isolation, rash care, and when to seek urgent care, especially during pregnancy or if you have high fever or severe symptoms.

• Antiviral use is not routine for all cases.
• Long-term public health monitoring is required to prevent outbreaks.

What is Measles?

Measles is a highly contagious viral illness caused by the measles virus. It typically presents with high fever, cough, runny nose, red eyes, and a spreading rash. Complications can be serious, especially in young children and adults with incomplete immunity.

In India, routine measles vaccination is part of immunization programs and is important for community protection. Seek medical advice promptly if measles is suspected, as early care supports fever management, hydration, and monitoring for potential complications.

Advantages of Measles
