RESUMO
BACKGROUND: Enteroviruses (EV) and parechoviruses (PeV) are ubiquitous viruses that cause a range of illness, including acute illness in children aged <1 year. OBJECTIVES: We describe EV and PeV infections among children from 2 US study sites aged <1 year and hospitalized with acute infections. For EV- and PeV-negative case-patients, we explored other viral etiologies. METHODS: Participants were aged <1 year, hospitalized during 2016, and had cerebrospinal fluid (CSF) collected for routine diagnostic testing. Demographic and clinical data were abstracted from medical charts, and residual specimens were sent to CDC for confirmatory testing and typing. RESULTS: Of 472 eligible case-patients, CSF specimen was available for 319 (67.6%). Among those, 13 (4.1%) were positive for EV and 11 (3.4%) for PeV. Most case-patients (86.8%, n = 277) were aged <2 months, as were all EV- or PeV-positive case-patients. None of the positive case-patients had underlying conditions, and the chief complaint for 91.7% (n = 22) was fever. Twelve positive case-patients were admitted to intensive care (ICU) and had brief hospital stays (median 2 days). Sequencing revealed a variety of EV types and the predominance of PeV-A3 among the PeV-positive case-patients. CONCLUSIONS: A range of EV and PeV types were associated with acute febrile illnesses leading to hospitalization in children aged <2 months. Approximately half of EV and PeV case-patients were admitted to ICU, but length of hospital stay was brief and illnesses were generally self-limiting. Clinicians should consider EV and PeV infections in infants presenting with febrile illness.

This systematic review examines the relationship between neighborhood characteristics and adolescent pregnancy, contraceptive use, sexual initiation, and birthrate. Several studies found a significant association between higher poverty and increased adolescent birthrate, pregnancy, and earlier age at sexual initiation. Unsafe neighborhoods were associated with earlier sexual initiation and increased adolescent pregnancy. Mixed results were found for neighborhood racial or ethnic composition. Lower collective efficacy and social support were associated with increased rates of adolescent pregnancy and earlier age at sexual initiation. Improved definitions of neighborhoods, as well as research on interactions between structural factors and social processes during adolescence is needed.
