Chickenpox complicated by pneumococcal meningitis: a rare coinfection

Abstract

Bacterial complications, particularly skin superinfections, are common during chickenpox. However, reports of acute bacterial meningitis associated with chickenpox are unusual and amount to only a very few observations. For the most part, they are caused by Neisseria meningitidis or Streptococcus pyogenes. We report an infrequent occurrence of pneumococcal meningitis 2 days after the onset of a chickenpox rash in a 7-year-old previously healthy boy. Based on data from the literature, we attempt to understand the possible mechanisms resulting in bacterial complications, particularly meningitis, during chickenpox and to determine the means to prevent it.
