“…Transmission of SARS-CoV-2 occurs between members of households [ 66 ]. Latino households in Baltimore had a secondary attack rate of 45.8%, and higher household transmission was associated with socioeconomic vulnerability, living in poor areas, and denser housing [ 67 ]. In our study population, a higher proportion of patients who were Hispanic/Latino reported a multimember COVID-19 household compared with patients of other races/ethnicities.…”

Background Studies of inpatient COVID-19 mortality risk factors have mainly used data from academic medical centers or large multi-hospital databases and have not examined populations with large proportions of Hispanic/Latino patients. In a retrospective cohort study of 4,881 consecutive adult COVID-19 hospitalizations at a single community hospital in Los Angeles County with a majority Hispanic/Latino population, we evaluated factors associated with mortality. Methods Data on demographic characteristics, comorbidities, laboratory and clinical results, and COVID-19 therapeutics were abstracted from the electronic medical record. Cox proportional hazards regression modelled statistically significantly independently associated predictors of hospital mortality. Results Age ≥ 65 years (HR = 2.66; 95% CI = 1.90, 3.72), male sex (HR = 1.31; 95% CI = 1.07, 1.60), renal disease (HR = 1.52; 95% CI = 1.18, 1.95), cardiovascular disease (HR = 1.45; 95% CI = 1.18, 1.78), neurological disease (HR = 1.84; 95% CI = 1.41, 2.39), D-dimer ≥ 500 ng/ml (HR = 2.07; 95% CI = 1.43, 3.0), and pulse oxygen level < 88% (HR = 1.39; 95% CI = 1.13, 1.71) were independently associated with increased mortality. Patient household with multiple COVID-19 cases, and Asian, Black, or Hispanic compared to White non-Hispanic race/ethnicity were associated with reduced mortality. In hypoxic COVID-19 inpatients, remdesivir, tocilizumab, and convalescent plasma were associated with reduced mortality, and corticosteroid use with increased mortality. Conclusions We corroborate several previously identified mortality risk factors and find evidence that the combination of factors associated with mortality differ between populations.

“…[8] However, few published studies have characterized which household contacts and household units are most likely to engage in behaviors that interrupt transmission, and the structural barriers that can prevent them from doing so, including high household living density. [10,11] The aims of the current study are 1) to describe changes in household contacts' COVID-19 mitigating behaviors (e.g., mask-wearing, sharing a bedroom with primary infected case) between cohort entry and Day 14 of cohort participation and 2) to identify structural and individual-level factors associated with these behaviors at Day 14. We analyzed behavioral data from the COVID-19 Household Transmission Study (CO-HOST), a racially and ethnically diverse cohort of household transmission in central North Carolina conducted from April to October 2020, encompassing rural, suburban and urban households.…”

Background: SARS-CoV-2 transmission frequently occurs within households, yet few studies describe which household contacts and household units are most likely to engage in transmission-interrupting behaviors. Methods: We analyzed a COVID-19 prospective household transmission cohort in North Carolina (April-Oct 2020) to quantify changes in physical distancing behaviors among household contacts over 14 days. We evaluated which household contacts were most likely to ever mask at home and to ever share a bedroom with the index case between Days 7-14. Results: In the presence of a household COVID-19 infection, 24% of household contacts reported ever masking at home during the week before study entry. Masking in the home between Days 7-14 was reported by 26% of household contacts, and was more likely for participants who observed their household index case wearing a mask. Participants of color and participants in high-density households were more likely to mask at home. After adjusting for race/ethnicity, living density was not as clearly associated with masking. Symptomatic household contacts were more likely to share a bedroom with the index case. Working individuals and those with comorbidities avoided sharing a bedroom with the index case. Conclusion: In-home masking during household exposure to COVID-19 was infrequent in 2020. In light of ongoing transmission of SARS-CoV-2, these findings underscore a need for health campaigns to increase the feasibility and social desirability of in-home masking among exposed household members. Joint messaging on social responsibility and prevention of breakthrough infections, reinfections, and long COVID-19 may help motivate transmission-interruption behaviors.
