Paediatrics: Whooping Cough: Free MSRA Podcast

🩺 FREE MSRA PODCAST – Whooping Cough (Pertussis): Not Just a Childhood Disease! 🌬️Today’s episode drills down into whooping cough (pertussis), a highly contagious bacterial infection with classic dramatic coughing fits. Perfect for MSRA revision or clinical knowledge—covering key facts, exam essentials, and practical memory tips!🧠 Key Learning Points📌 Definition• Whooping cough (pertussis) = acute, highly contagious respiratory infection• Caused by Bordetella pertussis bacteria• Characterised by severe, prolonged coughing fits, often followed by a “whoop” sound on inhalation📌 Causes & Risk Factors• Transmission via respiratory droplets (coughing/sneezing)• Unvaccinated/partially vaccinated infants at highest risk• Also affects teens & adults (often under-recognised); adults can act as a reservoir• Close contact = major transmission risk📌 Pathophysiology• Bacteria attach to airway lining, release toxins• Toxins damage cilia (tiny airway hairs) → impaired mucus clearance• Triggers airway inflammation, excess mucus, and narrowing—> leads to classic cough📌 Epidemiology• Still common in UK: ~1,000–3,600 cases/year• Peaks every 3–4 years, periodic outbreaks• 2012: Led to vaccine for pregnant women (protecting newborns)• 2019: 74% of cases were teens/adults (15+); 1 in 5 schoolchildren with a persistent cough showed evidence of infection—even if vaccinated!📌 Clinical Presentation: 3 Stages (CPC)Catarrhal: Cold-like, runny nose, mild cough (most infectious phase!)Paroxysmal: Intense, rapid coughing fits, inspiratory “whoop”, post-tussive vomiting, apnoea in infantsConvalescent: Gradual recovery, but cough may linger for weeks (the “100-day cough”)📌 Diagnosis• Clinical suspicion (classic history & exam)• PCR or serology preferred for confirmation (nasopharyngeal swab)• Notify Public Health England on suspicion—don’t wait for results!• Chest X-ray if complications suspected📌 Management• Prevention = key! Routine vaccinations (2, 3, 4 months + preschool booster); maternal vaccination in pregnancy• Antibiotics (macrolides: azithro-/clarithro-/erythromycin) – Most effective if given <21 days from cough onset – Reduces infectivity (non-infectious 5 days after starting), NOT cough duration• Supportive care: hospitalise infants/very unwell; treat complications• Exclusion from school/nursery: 48 hrs after antibiotics start, or 21 days if untreated• Offer antibiotics to close household contacts (prophylaxis)📌 Complications• Pneumonia (most common serious complication)• Apnoea, seizures, encephalopathy• Subconjunctival haemorrhages, rib fractures, hernias (from forceful coughing)• Long-term: bronchiectasis, neurological damage, death (esp. infants <6 months)📝 Memory Aids:CPC = Catarrhal, Paroxysmal, ConvalescentAntibiotics = Stop Spread, NOT Cough100-Day Cough📎 More MSRA Resources for Whooping Cough (Pertussis):📝 Revision Notes: https://www.passthemsra.com/topic/whooping-cough-pertussis-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/whooping-cough-pertussis-flashcards/💬 Accordion Q&A: https://www.passthemsra.com/topic/whooping-cough-pertussis-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/whooping-cough-pertussis-rapid-quiz/🎓 Paediatrics Course: https://www.passthemsra.com/courses/paediatrics-for-the-msra/#MSRA #WhoopingCough #Pertussis #MSRAQuiz #PassTheMSRA #FreeMSRA #ChildHealth #Vaccination #100DayCough #Paediatrics #NICEguidelines
