Risk and Protective Factors for COVID-19 Infection among Pregnant Women with Sickle Cell Trait.

Pregnant women and individuals with sickle cell trait (SCT) and underlying comorbidities are both independently more vulnerable to severe illness from coronavirus disease 2019 (COVID-19) compared to nonpregnant women and those without SCT. However, our understanding of the specific factors influencing susceptibility to COVID-19 infection among pregnant women with SCT is currently constrained by limited available data. This study aims to determine the risk and protective factors that influence the likelihood of COVID-19 infection in this population.

Application of plant metabarcoding to identify diverse honeybee pollen forage along an urban-agricultural gradient.

Understanding animal foraging ecology requires large sample sizes spanning broad environmental and temporal gradients. For pollinators, this has been hampered by the laborious nature of morphologically identifying pollen. Identifying pollen from urban environments is particularly difficult due to the presence of diverse ornamental species associated with consumer horticulture.

Enhanced One Health Surveillance during the 58th Presidential Inauguration-District of Columbia, January 2017.

Objective: In January 2017, Washington, DC, hosted the 58th United States presidential inauguration. The DC Department of Health leveraged multiple health surveillance approaches, including syndromic surveillance (human and animal) and medical aid station-based patient tracking, to detect disease and injury associated with this mass gathering.

Methods: Patient data were collected from a regional syndromic surveillance system, medical aid stations, and an internet-based emergency department reporting system.

Centers for Disease Control and Prevention's Temporary Epidemiology Field Assignee program: Supporting state and local preparedness in the wake of Ebola.

Objectives: The Centers for Disease Control and Prevention launched the Temporary Epidemiology Field Assignee (TEFA) Program to help state and local jurisdictions respond to the risk of Ebola virus importation during the 2014-2016 Ebola Outbreak in West Africa. We describe steps taken to launch the 2-year program, its outcomes and lessons learned.

Methods: State and local health departments submitted proposals for a TEFA to strengthen local capacity in four key public health preparedness areas: 1) epidemiology and surveillance, 2) health systems preparedness, 3) health communications, and 4) incident management.
