Table 2 Pneumococcal colonization of children in Kibera and Lwak, 2009–2010 surveys combined

From: Pneumococcal carriage and antibiotic susceptibility patterns from two cross-sectional colonization surveys among children aged <5 years prior to the introduction of 10-valent pneumococcal conjugate vaccine — Kenya, 2009–2010

  1. NA not applicable
  2. *P = 0.009 comparing pneumococcal colonization among all children aged <1 years vs. 1–4 years
  3. a P value was not calculated as at least one of the cell counts were <5
