Which condition is a common postnatal central nervous system infection affecting infants?

• A. Central Nervous System infection (encephalitis, meningitis)
• B. Neonatal jaundice
• C. Asthma
• D. Neonatal seizures

Answer: (A)

In infants, infections of the central nervous system after birth most commonly take the form of meningitis or encephalitis. The newborn period is a window of vulnerability because the immune system and the blood–brain barrier are still immature, so pathogens can more easily affect the brain and meninges. These infections often present with nonspecific signs such as fever or irritability, poor feeding, lethargy, vomiting, and sometimes a bulging fontanelle, and they can be associated with seizures. Neonatal jaundice is due to bilirubin metabolism issues in the liver, not a CNS infection. Asthma is a chronic airway inflammatory condition, unrelated to CNS infections. Neonatal seizures can occur with CNS problems but are a symptom rather than the infection itself. Therefore, the best answer is the central nervous system infection category (encephalitis, meningitis).
