In the United Kingdom, the 23-valent pneumococcal polysaccharide vaccine (PPV23) is recommended in addition to routine pneumococcal conjugate vaccination for at-risk children aged ≥2 years. This study describes the epidemiology, serotype distribution, clinical characteristics, vaccination status, and reasons for nonvaccination in children aged 5-15 years with invasive pneumococcal disease (IPD). ⋯ Only a quarter of children with comorbidities who developed IPD had received PPV23 prior to infection. Among PPV23-vaccinated children with comorbidities, however, there was no evidence of protection against PPV23 serotypes.

Pretravel health consultations help international travelers manage travel-related illness risks through education, vaccination, and medication. This study evaluated costs and benefits of that portion of the health consultation associated with malaria prevention provided to US travelers bound for West Africa. ⋯ Our model suggests that healthcare payers save money for short- and longer-term trips, and that travelers save money for longer trips when travelers adhere to malaria recommendations and prophylactic regimens in West Africa. This is a potential incentive to healthcare payers to offer consistent pretravel preventive care to travelers. This financial benefit complements the medical benefit of reducing the risk of malaria.

Previous studies, largely based on chart reviews with small sample sizes, have demonstrated that infectious diseases (ID) specialists positively impact patient outcomes. We investigated how ID specialists impact mortality, utilization, and costs using a large claims dataset. ⋯ ID interventions are associated with improved patient outcomes. Early ID interventions are also associated with reduced costs for Medicare beneficiaries with select infections.
