A case of Japanese encephalitis in a Victorian infant

A previously well 4‐month‐old boy was admitted to a tertiary Victorian paediatric hospital in February 2022 following a febrile convulsion. He had a 2‐day prodrome characterised by fevers to 39°C and reduced energy and feeding. The self‐limiting febrile convulsion occurred on day 3 of illness and was characterised by left eye deviation, tonic extension of upper limbs, shallow breathing, and pallor. He did not appear unwell on initial examination and no convincing source of fevers was identified. He was born at term and was developing appropriately for age.
