Factors related to adherence to public COVID-19 prevention behaviors, United States, April–July 2021

Introduction Omicron cases are surging in a pandemicweary US population. As breakthrough infections increase, and with just about a quarter of the US vaccinated population having received a booster dose, adherence to non-pharmacological anti-contagion measures is critical. We examined prevalence, trends, and correlates of adherence to non-pharmacological anti-contagion measures. Methods We used cross-sectional data from six cycles of the Household Pulse Survey during April–July 2021. The Pulse Survey is a telephone-based survey of adults aged ≥18 years in all 50 US states and D.C. Between 66262 and 78467 US adults completed each survey cycle (pooled n=425460). Results During the most recent cycle analyzed (23 June–5 July 2021), 13.6% of US adults reported ever COVID-19 diagnosis, ranging from 5.0% in Hawaii to 20.5% in North Dakota; in New York State, prevalence was 14.0%. Overall, 80.9% reported having received ≥1 dose of a COVID-19 vaccine during 23 June–5 July 2021, ranging from 93.5% in D.C. to 60.1% in Wyoming; in New York State, prevalence was 83.0%. Within trend analysis over the six survey cycles (14 April–5 July 2021), the percentage of vaccinated adults who reported ‘I have decreased prevention behaviors since getting a vaccine’ increased from 10.1% at baseline during 14 April–26 April 2021, to 52.5% during 23 June–5 July 2021 (p
