Prevalence of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Antibodies in the Mozambican Population: A Cross-Sectional Serologic Study in 3 Cities, July-August 2020.

BACKGROUND: The extent of population exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was uncertain in many African countries during the onset of the pandemic. METHODS: We conducted a cross-sectional study and randomly selected and surveyed general population and occupational groups from 6 July to 24 August 2020, in 3 cities in Mozambique. Anti-SARS-CoV-2-specific immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies were measured using a point-of-care rapid test. The prevalence was weighted for population (by age, sex, and city) and adjusted for test sensitivity and specificity. RESULTS: A total of 21 183 participants, including 11 143 from the general population and 10 040 from occupational groups, were included across all 3 cities. General population seropositivity (IgM or IgG) prevalence was 3.0% (95% confidence interval [CI], 1.0%-6.6%) in Pemba, 2.1% (95% CI, 1.2%-3.3%) in Maputo City, and 0.9% (95% CI, .1%-1.9%) in Quelimane. The prevalence in occupational groups ranged from 2.8% (95% CI, 1.3%-5.2%) to 5.9% (95% CI, 4.3%-8.0%) in Pemba, 0.3% (95% CI, .0%-2.2%) to 4.0% (95% CI, 2.6%-5.7%) in Maputo City, and 0.0% (95% CI, .0%-.7%) to 6.6% (95% CI, 3.8%-10.5%) in Quelimane, and showed variations between the groups tested. CONCLUSIONS: In the first representative COVID-19 serosurveys in Mozambique, in mid-2020, weighted and assay-adjusted seroprevalence in 3 provincial capitals of anti-SARS-CoV-2 ranged from 0.9% to 3.0%, whereas adjusted prevalence in occupational groups ranged from 0.0% to 6.6% with variation between groups. Exposure to SARS-CoV-2 was extensive during the first pandemic wave, and transmission may have been more intense among occupational groups. These data have been of utmost importance to inform public health intervention to control and respond to the pandemic in Mozambique.

A Culturally and Linguistically Appropriate Telephone Support Intervention for Diverse Family Caregivers of Persons With Dementia During the COVID-19 Pandemic.

Caregivers of persons with dementia (PWDs) were socially isolated with little support during the COVID-19 pandemic "Stay-At-Home" order in the United States. To enhance social and emotional connection for diverse caregivers, a culturally/linguistically appropriate telephone intervention provided compassionate listening, mindful breathing, and COVID-19 safety education. The study purpose was to understand caregiving challenges and to evaluate the intervention for caregivers during the early pandemic using a qualitative approach. Twenty-three caregivers participated in the intervention provided by bilingual research assistants for 3 months. Call logs were used to describe the caregivers' dialogue. Thematic analysis identified (a) the challenges, including fear of coronavirus disease, providing around-the-clock care, and forced isolation and negative emotions; and (b) caregivers' experience with the intervention, including connecting with the outside, relief from emotional stress, reliable COVID-19 information, and reinformed caregiving skills. Results suggest that the telephone support was of benefit to diverse caregivers of PWDs during the pandemic by promoting social connection and reducing emotional distress.

Telephone support for dementia family caregivers during the COVID-19 pandemic: Experiential differences in spouse and adult-child caregivers

Background Due to the COVID-19 pandemic, family caregivers stayed home with their person with dementia (PWD) continuously for 24/7. They faced limited social activity with lack of essential services such as adult daycare and in-home services. Social restrictions can worsen cognitive deterioration and increase behavioral problems of PWD, causing increased caregiver burden, distress, and loneliness. Caregiver research team developed a telephone support intervention with trained university students who provided emotional support, and COVID-19 information. The objective of the study is to identify the different needs in caring between spousal caregivers and adult-child caregivers for community-dwelling PWD during this pandemic. Methods Family caregivers were recruited through our previous home-visit family caregiver study. Trained bilingual university students conducted telephone support calls in English, Spanish, Korean or Vietnamese as preferred by caregiver participants, once a week during the 3 month of the early pandemic period. Students summarized each conversation in a call log for debriefing by a gerontology faculty. Thematic analysis using call logs was conducted and coded by two independent raters by using Dedoose, a qualitative data analysis tool. Similarities and differences between spousal caregivers and adult-child caregivers were identified. Results 14 spousal caregivers (11 were wives and 3 were husbands, mean age 67.4) and 11 adult-child caregivers (daughters, mean age 49) participated in the study. Three themes were identified: (1) spousal caregivers had high sense of being left alone and isolated while adult-child caregivers felt a greater responsibility for the family including PWD care, (2) both groups showed increased stress but for spouse caregivers it was due to worsening PWD behaviors, for adult-child caregivers it was the restriction on social interaction and concerns about losing jobs, (3) similarities in adapting to the COVID-19 safety recommendations and incorporating it into everyday life. Conclusion The findings showed an increase in stress and anxiety in both groups but the differences were: for spouse high level of loneness, difficulty with PWD behaviors;for adult-child caregivers greater burden due to family and reduced social life. Both groups followed COVID-19 safety protocol and highly appreciated the telephone-based emotional support during the pandemic.

Coronavirus Disease Contact Tracing Outcomes and Cost, Salt Lake County, Utah, USA, March-May 2020.

Outcomes and costs of coronavirus disease (COVID-19) contact tracing are limited. During March-May 2020, we constructed transmission chains from 184 index cases and 1,499 contacts in Salt Lake County, Utah, USA, to assess outcomes and estimate staff time and salaries. We estimated 1,102 staff hours and $29,234 spent investigating index cases and contacts. Among contacts, 374 (25%) had COVID-19; secondary case detection rate was ≈31% among first-generation contacts, ≈16% among second- and third-generation contacts, and ≈12% among fourth-, fifth-, and sixth-generation contacts. At initial interview, 51% (187/370) of contacts were COVID-19-positive; 35% (98/277) became positive during 14-day quarantine. Median time from symptom onset to investigation was 7 days for index cases and 4 days for first-generation contacts. Contact tracing reduced the number of cases between contact generations and time between symptom onset and investigation but required substantial resources. Our findings can help jurisdictions allocate resources for contact tracing.
