CDC Recommendations at This Level

Major measles outbreak — take immediate action

  • The CDC urges MMR vaccination for anyone not already protected — the vaccine is safe and highly effective
  • Keep unvaccinated children home from school and daycare if your area has active cases
  • If you develop fever, cough, and rash, isolate immediately and call your healthcare provider
  • Pregnant women who are not immune should avoid exposure and consult their OB
  • Check with your local health department for outbreak-specific guidance in your area

This is general public health guidance based on CDC recommendations — not personal medical advice. Talk to your healthcare provider about what's right for you and your family.
