Fever, marked tachycardia and vesiculobullous rash in an infant with Chikungunya fever

We describe a 3-month-old male infant who presented with acute onset fever, irritability and marked tachycardia. ECG was suggestive of atrial tachycardia. He developed erythematous blanchable skin rash on day 2 of illness, which progressed to vesiculobullous lesions over a few days’ time. The child was managed with intravenous adenosine, carefully monitored fluid boluses, oxygen supplementation and close monitoring. Tachycardia improved within 24 hours. Blood for Chikungunya PCR was positive. The child was discharged after 5 days of hospitalisation with bullous lesions evolving into hyperpigmented macules followed by crusts and hypopigmentation by day 10.
