Graduated Driver Licensing Night Driving Restrictions and Fatal Night Crashes — 40 States, 2009–2014

Strategies to further reduce overall fatal crashes by newly licensed teen drivers should address night crashes. States could consider updating their GDL night driving restriction coverage to include earlier nighttime hours. Fatal crash risk is higher at night for all drivers, but especially for young, inexperienced drivers. To help address the increased crash risk for beginner teen drivers, 49 states and the District of Columbia include a night driving restriction in their Graduated Driver Licensing (GDL) system. However, 23 states and the District of Columbia have night driving restrictions that begin at midnight or later, times when most teen drivers subject to GDL are not driving. According to a new CDC study of drivers aged 16 or 17 years involved in fatal crashes nationwide during 2009–2014, 31% were involved in night crashes (9:00 p.m.–5:59 a.m.). Of drivers involved in fatal night crashes, 57% crashed before midnight.

Mumps Outbreak at a University and Recommendation for a Third Dose of Measles-Mumps-Rubella Vaccine — Illinois, 2015–2016

Though evidence of its effectiveness is needed, a third dose of MMR vaccine may be considered as a control measure during mumps outbreaks occurring in settings in which persons are in close contact with one another, where transmission is sustained despite high two-dose coverage with MMR vaccine, and when traditional control measures fail to slow transmission. On May 1, 2015 the Illinois Department of Public Health (IDPH) confirmed a mumps outbreak at a large Illinois university. By March 15, 2016, 237 cases had been identified in the outbreak. IDPH responded to the outbreak by recommending a third MMR dose to the university community as a control measure. This report describes the epidemiology of the mumps outbreak and details the rationale for the recommendation, which may assist public health agencies considering similar recommendations in outbreak settings.

State and Regional Prevalence of Diagnosed Multiple Chronic Conditions among Adults Aged ≥18 Years — United States, 2014

Within the United States there are significant state and regional prevalence differences in diagnosed multiple chronic conditions (MCC). These geographic disparities in MCC prevalence may inform state-level surveillance efforts and targeted service delivery or resource allocation for MCC prevention efforts. An examination of prevalence of diagnosed multiple chronic conditions (MCC) among U.S. adults revealed state and regional differences throughout the United States. State-level prevalence estimates among adults range from 19.0% in Colorado to 38.2% in Kentucky. MCC prevalence among adults also varies by region, ranging from 21.4% in the Pacific region to 34.5% in the East South Central region. Furthermore, prevalence of MCC was higher among women compared to men within certain U.S. regions, and increased with advancing age among all regions.
