Occult bacteraemia in children with fever without focus though previously vaccinated against pneumococcus.

Pneumococcal conjugate vaccines (PCV) have reduced the rate of occult bacteraemia in developed countries. However, reports on the incidence of occult bacteraemia in tropical regions are scarce. The aim of our study was to determine its frequency in children consulting for fever without focus in Colombia after introduction of the pneumococcal conjugate vaccines. We concluded that in tropical areas, testing for occult bacteraemia should be considered regardless of previous pneumococcal conjugate vaccination status.
