Travel history among persons infected with SARS-CoV-2 variants of concern in the United States, December 2020-February 2021.

The first three SARS-CoV-2 phylogenetic lineages classified as variants of concern (VOCs) in the United States (U.S.) from December 15, 2020 to February 28, 2021, Alpha (B.1.1.7), Beta (B.1.351), and Gamma (P.1) lineages, were initially detected internationally. This investigation examined available travel history of coronavirus disease 2019 (COVID-19) cases reported in the U.S. in whom laboratory testing showed one of these initial VOCs. Travel history, demographics, and health outcomes for a convenience sample of persons infected with a SARS-CoV-2 VOC from December 15, 2020 through February 28, 2021 were provided by 35 state and city health departments, and proportion reporting travel was calculated. Of 1,761 confirmed VOC cases analyzed, 1,368 had available data on travel history. Of those with data on travel history, 1,168 (85%) reported no travel preceding laboratory confirmation of SARS-CoV-2 and only 105 (8%) reported international travel during the 30 days preceding a positive SARS-CoV-2 test or symptom onset. International travel was reported by 92/1,304 (7%) of persons infected with the Alpha variant, 7/55 (22%) with Beta, and 5/9 (56%) with Gamma. Of the first three SARS-CoV-2 lineages designated as VOCs in the U.S., international travel was common only among the few Gamma cases. Most persons infected with Alpha and Beta variant reported no travel history, therefore, community transmission of these VOCs was likely common in the U.S. by March 2021. These findings underscore the importance of global surveillance using whole genome sequencing to detect and inform mitigation strategies for emerging SARS-CoV-2 VOCs.

Travel from the United Kingdom to the United States by a Symptomatic Patient Infected with the SARS-CoV-2 B.1.1.7 Variant - Texas, January 2021.

In December 2020, the B.1.1.7 genetic variant of SARS-CoV-2, the virus that causes COVID-19, was first reported after emergence and rapid circulation in the United Kingdom (1). Evidence suggests that the B.1.1.7 variant is more efficiently transmitted than are other SARS-CoV-2 variants, and widespread circulation could thereby increase SARS-CoV-2 infection and hospitalization rates (1,2). The first reported SARS-CoV-2 B.1.1.7 variant case in the United States was confirmed by sequencing in Colorado on December 29, 2020.* This report describes a person who traveled from the United Kingdom to the United States after experiencing COVID-19-compatible symptoms† and was eventually confirmed to be infected with the B.1.1.7 variant.

Telephone-based, cognitive-behavioral therapy for African American dementia caregivers with depression: initial findings.

OBJECTIVES: Discuss initial findings of a randomized clinical trial comparing the effects of telephone-based and face-to-face (f-to-f) cognitive-behavioral therapy (CBT) on changes in caregiver (CG) burden, assistance support, depression, and health status for African American (AA) CGs with depression. DESIGN: Pilot study using a prepost, two-group design with 14 enrolled and randomized participants. MEASURES: Subjective Burden subscale of the Caregiver Appraisal Inventory, Assistance Support subscale of the Interpersonal Support Evaluation List, Physical Symptoms subscale of the Caregiver Health and Health Behavior Inventory and the Center for Epidemiologic Studies Depression Scale. RESULTS: Prepost improvements were found on 11 completers across all measures for both telephone and f-to-f CBT. Moderate and similar effects sizes for CG subjective burden and assistance support were found for both the telephone and f-to-f groups. Effect sizes for physical symptoms and depression varied from low to moderate, respectively, with a trend toward smaller improvements in f-to-f CBT than in telephone CBT. Qualitative analysis highlighted CGs' perceptions of the active ingredients of treatment and provided indirect support for similar gains in emotional and psychosocial functioning across the two treatment modalities. CONCLUSIONS: Both telephone-based and f-to-f CBT showed improvements in depression, subjective burden, and assistance support in dementia AA CGs. Replication with a larger sample size (N = 106) is currently in progress. Study limitations and future directions for research are also addressed.
