In Case You Missed It: MMWR and COVID

Center for Disease Control's Morbidity and Mortality Weekly ReportThe Homeland Security Digital Library (HSDL) maintains a collection of the Centers for Disease Control‘s (CDC) Morbidity and Mortality Weekly Report (MMWR), which collects and analyzes data from the United States Department of Health and Human Services (HHS) on epidemiology and public health. Each issue of the MMWR is packed with raw and analyzed public health data and scientific studies from some of the top minds in the United States. In light of the COVID-19 (coronavirus disease 2019) epidemic, we are highlighting some of the most current and informative COVID-related studies included in their weekly reports.

Here are some articles you may have missed from Volume 69, Issues 33-36 of the Centers for Disease Control’s Morbidity and Mortality Weekly Report (MMWR) Series.

Community and Close Contact Exposures Associated with COVID-19 Among Symptomatic Adults ≥18 Years in 11 Outpatient Health Care Facilities

This study finds that community and close-contact exposure (primarily via on-site dining restaurants) continues to drive the spread of COVID-19. Interestingly, adults with positive COVID results are reportedly twice as likely to dine out as adults with negative test results. Efforts to reduce the spread of the virus are hampered by these types of establishments because masks cannot be effectively worn while eating and drinking.

Timing of State and Territorial COVID-19 Stay-at-Home Orders and Changes in Population Movement

This study finds that states and communities with strict/mandatory stay-at-home orders had lower instances of population movement, which limited exposure and reduced the transmission of the novel coronavirus. In communities where shelter-in-place orders were lifted, increases in population movement were detected, which can potentially increase the spread of COVID-19.

Mass Testing for SARS-CoV-2 in 16 Prisons and Jails — Six Jurisdictions

This article outlines the difficulty of containing COVID-19 in correctional and detention facilities. The challenges associated with this include the close quarters and high rates of chronic illnesses in inmates. The research suggests mass testing is more beneficial than symptom-based testing only for long term containment of the virus.

Disparities in Incidence of COVID-19 Among Underrepresented Racial/Ethnic Groups in Counties Identified as Hotspots

Researchers are finding that people of color are significantly more likely to be affected by COVID-19. Counties with hotspots of COVID cases have disproportionately high cases of infection among Hispanic and black residents. Factors that contribute to this include people of color holding a higher percentage of “essential” jobs, living in multi-generational households, and facing discrimination in health care.
