Key Evidence: Among both HIV positive and HIV negative parents in a study in Kenya, 99% of pneumococcal strains found and tested were resistant to one or more antibiotics. HIV positive parents carried 16% more strains that were resistant to penicillin than those carried by HIV negative parents.
Key Evidence: Two years after the introduction of 10-strain pneumococcal conjugate vaccine (PCV-10) in Kenya, the percent of HIV-positive adults who carried pneumococcal bacteria declined significantly (from 43% to 28%), but did not decline in HIV-negative adults. However, the reduction in carriage of pneumococcal strains that are in PCV10 declined significantly in both HIV-positive and HIV-negative adults. This reduction was still four times higher in HI- positive vs. HIV-negative adults (2.8% vs. 0.7%), indicating that HIV positive adults continue to be at considerably higher risk of invasive pneumococcal disease than HIV-uninfected adults.
From the VoICE Editors: Nasopharyngeal carriage is an indicator of the risk for invasive pneumococcal disease and pneumonia.
