Understanding Measles and Potential Symptoms

Measles is a highly contagious airborne disease that can cause serious health complications, particularly in vulnerable populations. Symptoms typically appear 7-21 days after exposure and include:

• Fever
• Unexplained rash
• Cough
• Congestion or runny nose
• Red, watery eyes (conjunctivitis)

Infants and children under 5 years old, pregnant women, and individuals with weakened immune systems are at the highest risk of developing complications from measles. The Centers for Disease Control and Prevention (CDC) provides comprehensive information on measles, its complications, and prevention.

Who is Protected?

Individuals are generally considered protected from measles if they:

• Were born in 1957 or earlier.
• Have received two doses of the Measles, Mumps, and Rubella (MMR) vaccine.
• Have documented laboratory evidence of immunity to the disease.

What to Do If You Think You’ve Been Exposed

If you visited either the Nissan dealership or the Wawa during the specified dates and times and are unsure of your immunity status, health officials recommend the following steps:

1. Check Your Vaccination Records: Verify your MMR vaccination history.
2. Monitor for Symptoms: Watch for the development of measles symptoms for 21 days after exposure.
3. Contact Your Healthcare Provider: If you develop symptoms, stay home and immediately contact your doctor, urgent care center, or hospital before your visit to allow them to seize appropriate precautions.
