✅ FREE MSRA PODCAST – Measles🎧 A clear, high-yield breakdown of this highly contagious viral illness – perfect for exam prep and real-life clinical scenarios.🧠 Key Learning Points📌 Definition• Measles (rubeola) is a highly contagious viral infection caused by a single-stranded RNA virus in the paramyxovirus family, primarily affecting the respiratory tract.📌 Causes & Risk Factors• Caused by the measles virus• Transmitted via airborne droplets or surfaces (viable up to 2 hours)• Risk factors: unvaccinated individuals, close contact in crowded settings💡 Mnemonic: "Unvaccinated + Unclean Air"📌 Pathophysiology• Infects respiratory epithelium → lymphatic spread → viraemia• Suppresses immune system → increased secondary infection risk• Rash caused by immune response, not direct viral damage📌 Symptoms• Prodrome: cough, coryza, conjunctivitis, high fever• Koplik spots (white spots on buccal mucosa)• Maculopapular rash starting behind ears → face → trunk• May include photophobia, diarrhoea, malaise💡 Mnemonic: “3 C’s + Koplik + Rash”📌 Differential Diagnosis• Rubella• Scarlet fever• Parvovirus B19• Enteroviruses• Kawasaki disease• Meningococcaemia• Drug reactions📌 Diagnosis• Clinical features (esp. Koplik spots + rash)• Confirm with IgM antibodies (oral/saliva/serum) or PCR• Notify public health—measles is notifiable in the UK💡 Mnemonic: “K-RASH + LAB”📌 Management• Supportive care: fluids, antipyretics, rest• Vitamin A: especially in young or immunocompromised patients• Isolation to prevent spread• MMR vaccination within 72h for exposed non-immune contacts• HNIG for high-risk contacts (e.g. pregnant, immunocompromised)📌 Complications• Pneumonia• Otitis media• Encephalitis• Subacute sclerosing panencephalitis (SSPE – fatal)• Diarrhoea, hepatitis, blindness (vitamin A deficiency)• Miscarriage or premature labour in pregnant women📌 Prognosis• Generally good in healthy individuals with access to care• High morbidity/mortality in malnourished or immunocompromised patients• Case fatality <0.01% in high-resource settings; >5% in low-income areas📎 More MSRA Resources for Measles📝 Revision Notes: https://www.passthemsra.com/topic/measles-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/measles-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/measles-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/measles-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/paediatrics-for-the-msra/#MSRA #MSRARevision #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards #MSRAQ&ANotes #MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision #MSRARevisionWebsite #Measles #Paediatrics
