Plasmodium vivax and Neisseria meningitidis co-infection in a newborn.

Invasive infections due to Neisseria meningitidis in Colombia are unusual in newborns, in contrast to infections due to Plasmodium vivax which is one of the main pathogens related to the presentation of fever in this age group, especially in the indigenous population. We report a case of co-infection of these two microorganisms in a child.
