Background: The SARS-CoV-2 outbreak prompted public health interventions and changes in public behavior that may have affected the 2019-2020 influenza season., Methods: Using data from a laboratory in southeastern Wisconsin, we compared the number of weekly influenza tests and their positivity rates during the 2019-2020 influenza season with the previous 4 seasons., Results: The number of influenza tests per week at the outset of the SARS-CoV-2 outbreak was higher than the average the previous 4 years, and positivity rates declined to 0% earlier than any of the previous 4 seasons., Conclusion: The testing trajectory and positivity rate for influenza differed during the part of the 2019-2020 season coinciding with the SARS-CoV-2 outbreak as compared to similar periods during the previous 4 seasons., (Copyright© Board of Regents of the University of Wisconsin System and The Medical College of Wisconsin, Inc.)

Background: Cancer health disparities by race, ethnicity, socioeconomic status, and geography are a top public health priority. Breast and colorectal cancer, in particular, have been shown to exhibit significant disparities and contribute a large proportion of morbidity and mortality from cancer. In addition, breast and colorectal cancer offer targets for prevention and control, including nutrition, physical activity, screening, and effective treatments to prolong and enhance the quality of survival. However, despite the investment of significant time and resources over many years, breast and colorectal cancer disparities persist, and in some cases, may be growing., Methods: This paper examines breast and colorectal cancer survival disparities in an 8-county region in southeastern Wisconsin, including the City of Milwaukee. Cox proportional hazards models were used to examine survival trends, and a new adaptation of adaptive spatial filtering--a disease mapping method--was used to examine spatial patterns of survival., Results: Disparities by race and ethnicity are revealed, and spatial analyses identify specific areas within the study region that have lower than expected survival rates., Conclusions: Cancer control efforts in southeastern Wisconsin should focus on black/African American and Hispanic/Latina women to reduce breast cancer survival disparities, and black/African American populations to reduce colorectal cancer disparities. Evidence indicates that targeted interventions may be needed to serve populations in the Milwaukee and Kenosha metropolitan areas, as well as areas of Walworth, Ozaukee, and Waukesha counties.

Background: Motor vehicle crashes are the leading cause of teenage deaths in the United States. Graduated Driver Licensing (GDL) policies effectively decrease teenage crash deaths. Emerging research is identifying the most effective components of GDL. This study examines GDL policies across 6 Great Lakes states, describing the beneficial impact, and investigating how evidence-based policy modifications could further reduce teenage driving deaths and injuries., Methods: GDL policies were reviewed in 6 Great Lakes states (Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin). Incidence rate ratios for fatal and injury crashes for 16-year-old drivers were obtained from the Nationwide Review of GDL Study. Ratios were applied to the fatal and injury crashes reported from each state between 2002 and 2006 for 16-year-old drivers. The potential impact (crashes avoided) for each state was determined based on the state using a 3-phase GDL policy (a learner and intermediate stage prior to full licensure). In addition, the impact on crash reductions for each state if they had employed 5 of the recommended GDL components was determined., Results: All 6 states had a 3-phase GDL policy, resulting in potential avoidance of 124 fatal and more than 21,000 injury crashes. The 6 states had 1 to 3 of the qualifying GDL components. If these states had adopted 5 of the qualifying components, an additional 309 fatal and more than 27,000 injury crashes could have been avoided., Conclusion: Three-phase GDL policy is effective at saving the lives of teenage drivers and vehicle occupants; evidence-based modification of GDL has the potential to further reduce teenage motor vehicle crash deaths and injuries.
