COVID-19 in Pregnancy: Occupations With Higher Density of Population Exposure Associated With More Severe Disease.

OBJECTIVE: To define the symptomatology of SARS-CoV-2 infection in pregnancy and associations between occupation, sociodemographic factors, and comorbidities with the severity of COVID-19 disease in pregnancy in all trimesters, regardless of hospitalization. METHODS: We studied a retrospective cohort of a public health surveillance sample of persons with COVID-19 infection diagnosed during pregnancy. Data was collected March 2020 to August 2020 regarding symptoms, disease severity, comorbidities, obstetric history, and occupation. RESULTS: One hundred sixty-three individuals were identified. Constitutional (64%) and lower respiratory symptoms (61%) were most common. Seventeen individuals (13.6%) were hospitalized, and one person (0.7%) died due to COVID-19. Risk factors for severe disease were age and an occupation that had high intensity exposure to people. CONCLUSIONS: Occupational exposure is a risk factor for severe COVID-19 disease in pregnancy, justifying policy measures to ensure protection of this vulnerable population.

Characterization of community-wide transmission of SARS-CoV-2 in congregate living settings and local public health-coordinated response during the initial phase of the COVID-19 pandemic.

BACKGROUND: Clusters of COVID-19 cases amplify the pandemic and are critical targets for intervention, but comprehensive cluster-level data are not collected systematically by federal or most state public health entities. This analysis characterizes COVID-19 clusters among vulnerable populations housed in congregate living settings across an entire community and describes early mitigation efforts. METHODS: The Cuyahoga County Board of Health identified and interviewed COVID-19 cases and exposed contacts, assessing possible connections to congregate living facilities within its jurisdiction from March 7, 2020, to May 15, 2020, during the first phase of the pandemic, while state of Ohio stay-at-home orders were in effect. A multi-disciplinary team-based response network was mobilized to support active case finding and develop facility-focused containment strategies. RESULTS: We identified a cascade of 45 COVID-19 clusters across community facilities (corrections, nursing, assisted living, intermediate care, extended treatment, shelters, group homes). Attack rates were highest within small facilities (P < .01) and large facilities requiring extensive support to implement effective containment measures. For 25 clusters, we identified an index case who frequently (88%) was a healthcare worker. Engagement of clinical, community, and government partners through public health coordination efforts created opportunities to rapidly develop and coordinate effective response strategies to support the facilities facing the dawning impact of the pandemic. CONCLUSIONS: Active cluster investigations can uncover the dynamics of community transmission affecting both residents of congregate settings and their caregivers and help to target efforts toward populations with ongoing challenges in access to detection and control resources.
