COVID-19 and MIS-C in Children Paediatrics Clinical Features Diagnosis Management
COVID-19 in children is usually mild but can sometimes lead to serious complications such as Multisystem Inflammatory Syndrome in Children MIS-C. This paediatrics guide explains the causes, pathophysiology, symptoms, diagnostic criteria, investigations, and complete management of COVID-19 and MIS-C in children. Learn about risk factors, complications, laboratory findings, treatment protocols including IVIG, corticosteroids, antiviral therapy, supportive care, and long-term follow-up. This comprehensive resource helps medical students, paediatricians, and healthcare professionals understand the differences between COVID-19 infection and post-infectious MIS-C, recognize warning signs early, and apply evidence-based treatment strategies for better outcomes in paediatric patients.

Frequently Asked Questions
❓ What is COVID-19 in children?
COVID-19 in children is an infection caused by the SARS-CoV-2 virus. Most children develop mild symptoms such as fever, cough, sore throat, fatigue, and gastrointestinal complaints, but some may develop severe disease or complications like MIS-C.
❓ What is MIS-C in paediatrics?
Multisystem Inflammatory Syndrome in Children (MIS-C) is a serious hyperinflammatory condition that occurs usually 2 to 6 weeks after COVID-19 infection. It involves multiple organs such as the heart, gastrointestinal system, skin, and nervous system.
❓ How common is severe COVID-19 in children?
Severe COVID-19 is less common in children compared to adults. Most pediatric cases are asymptomatic or mild, but infants, children with obesity, chronic disease, or immunodeficiency may develop severe illness.
❓ What are the common symptoms of COVID-19 in children?
Common symptoms include fever, cough, sore throat, runny nose, fatigue, headache, muscle pain, vomiting, diarrhea, and loss of taste or smell.
❓ What are the main symptoms of MIS-C?
MIS-C typically presents with persistent fever, abdominal pain, vomiting, diarrhea, rash, conjunctivitis, fatigue, low blood pressure, and signs of heart involvement.
❓ When does MIS-C usually occur after COVID infection?
MIS-C usually appears about 2 to 6 weeks after a child has had COVID-19 infection or exposure to the virus.
❓ How is MIS-C diagnosed?
MIS-C is diagnosed based on clinical criteria including persistent fever, laboratory evidence of inflammation, involvement of two or more organ systems, evidence of SARS-CoV-2 infection or exposure, and exclusion of other diagnoses.
❓ What laboratory findings are common in MIS-C?
Common laboratory findings include elevated CRP, ESR, ferritin, D-dimer, procalcitonin, troponin, BNP, lymphopenia, and thrombocytopenia.
❓ What is the first-line treatment for MIS-C?
The first-line treatment for MIS-C is intravenous immunoglobulin (IVIG). Corticosteroids are often added in moderate to severe cases.
❓ Why is echocardiography important in MIS-C?
Echocardiography is essential to evaluate cardiac involvement such as myocarditis, ventricular dysfunction, or coronary artery dilation and aneurysms.
❓ What medications are commonly used in MIS-C treatment?
Treatment may include IVIG, corticosteroids, aspirin, anticoagulants such as low molecular weight heparin, and biologic agents like tocilizumab in refractory cases.
❓ What complications can occur in MIS-C?
Complications include cardiogenic shock, myocarditis, coronary artery aneurysms, arrhythmias, thrombosis, and multiorgan failure.
❓ How is mild COVID-19 managed in children?
Mild COVID-19 in children is treated with supportive care such as rest, hydration, fever control with paracetamol, and monitoring symptoms at home.
❓ When is hospitalization required for pediatric COVID-19?
Hospitalization is required when children develop hypoxia, respiratory distress, dehydration, altered consciousness, or complications like MIS-C.
❓ Can COVID-19 affect the heart in children?
Yes, COVID-19 can cause myocarditis, arrhythmias, and cardiac dysfunction, especially in severe infection or MIS-C.
❓ What is the role of corticosteroids in pediatric COVID-19?
Corticosteroids such as dexamethasone are used in children with severe COVID-19 who require oxygen therapy to reduce inflammation.
❓ What is the difference between Kawasaki disease and MIS-C?
MIS-C occurs after COVID-19 infection and often presents with more severe inflammation, cardiac dysfunction, and gastrointestinal symptoms compared with classic Kawasaki disease.
❓ How long should children recovering from MIS-C avoid strenuous activity?
Children recovering from MIS-C should avoid strenuous physical activity for several months until cardiac evaluation confirms full recovery.
❓ Can children recover completely from MIS-C?
Most children recover completely with timely treatment, but long-term cardiac follow-up is necessary to monitor coronary artery changes and heart function.
❓ How can COVID-19 complications in children be prevented?
Prevention includes vaccination, good hygiene practices, mask use during outbreaks, early diagnosis, and prompt medical care for warning symptoms.
