Which term stands for 'Sudden infant death syndrome'?

• A. SIDS
• B. Bronchiolitis
• C. Intussusception
• D. Febrile Seizure

Answer: (A)

SIDS stands for Sudden Infant Death Syndrome—the unexpected death of an apparently healthy infant, usually during sleep, for which a thorough investigation cannot identify a cause. It's considered a diagnosis of exclusion, meaning no disease or injury explains the death after careful autopsy, examination of the death scene, and review of the infant’s history. Most cases occur in infants under six months, with a peak around 2–4 months. The other terms refer to distinct pediatric conditions: bronchiolitis is a viral infection causing inflammation of the small airways; intussusception is when a part of the intestine folds into another part, leading to obstruction; febrile seizures are seizures that occur in the context of fever. SIDS is the acronym that matches the description in the question.
