Abstract:
Non-pharmaceutical interventions (NPIs), such as masking and social distancing, can reduce SARS-CoV-2 transmission. Longitudinal behavioral data in individuals with acute respiratory illness (ARI) during the COVID-19 pandemic are limited. We describe changes in adherence to NPIs and the impact of ARIs on work or school in families before and during the COVID-19 pandemic. Methods From November 2019 to June 2021, households with school-aged children in King County, WA, were remotely monitored on a weekly basis for symptoms of respiratory illness. Participants with ARI (cough or ≥2 qualifying symptoms) were asked about illness-related behavior changes (e.g. masking, isolation, hand hygiene, surface cleaning, public transit use) and impacts on school/work 7 days after initial symptom report. Using generalized estimating equations for household clusters, we compared the frequency of behavior changes and school/work impact during 3 time periods: the pre-/early COVID-19 pandemic period (11/14/19-3/22/20), pre-vaccine period (3/23/20-12/10/20), and post-COVID-19 vaccine period (12/11/20-6/19/21). Results Of 1861 participants in 470 households, 695 (37%, from 70% of households) reported 1157 ARIs. Over the 3 time periods, the percent of ill participants who reported staying home (34 vs 34 vs 54%, respectively, P & lt; .001), avoiding contact with others (25 vs 28 vs 45%, P & lt; .001), and masking (3 vs 23 vs 38%, P & lt; .001) increased (Fig 1A). Other illness-related behaviors, including washing hands and disinfecting surfaces, were unchanged over time. The percent of ill participants who worked from home (7 vs 9 vs 3%, P= .02) and missed work due to ARI (13 vs 8 vs 8%, P= .03) decreased over time (Fig 1B). Figure 1A.Participant reported illness-related health behaviors in the past week — Seattle, WA, 2019–2021.Figure 1B.Participant reported illness-related school or work impact in the past week due to illness — Seattle, WA, 2019–2021 Time periods were defined as: Period 1: 11/14/19 – 3/22/20 (pre-/early COVID-19 pandemic), Period 2: 3/23/20 – 12/10/20 (post-Washington State Stay at Home order), and Period 3: 12/11/20 – 6/19/21 (United States Food and Drug Administration Emergency Use Authorization for the Pfizer-BioNTech COVID-19 vaccine for those 16 years and older). Illness was defined per Acute Respiratory Illness (ARI) case definition: cough or two qualifying symptoms (fever, sore throat, runny nose, muscle or body aches, headache, difficulty breathing, fatigue, nausea or vomiting; for participants & lt; 18 years of age, ear pain or drainage, rash, and diarrhea were also qualifying symptoms). Conclusion As the COVID-19 pandemic progressed, households with school-aged children engaged in isolation, social distancing, and masking more frequently in response to ARI. The impact of ARIs on work decreased during the pandemic. Disclosures Janet A.
