Measles: A Rash from the Past-Measles: A Rash from the Past

Video Transcription

Video Summary

Michael Gooch, an emergency and flight nurse practitioner, discusses the resurgence of measles in the US after it was declared eradicated in 2000. Cases have surged, particularly in Texas and New Mexico, largely among unvaccinated pediatric patients. Measles, a highly contagious viral disease with an R0 of 12-18, presents with fever, cough, conjunctivitis, and a characteristic rash. Complications can include pneumonia, encephalitis, and immune amnesia. Vaccination offers 97-98% immunity with two doses, but herd immunity has fallen below the critical 95%, increasing risk. Diagnosis is clinical but confirmed by IgM antibody tests and PCR. Management is mainly supportive with vitamin A supplementation recommended for pediatric patients to reduce severity and complications. Isolation with airborne precautions is crucial due to high contagion. Post-exposure prophylaxis includes MMR vaccination within 3 days or immune globulin within 6 days of exposure for those ineligible for vaccination. Measles remains a serious health threat underscoring the importance of vaccination and public health vigilance.
