Public health recommendations aimed at limiting spread of SARS-CoV-2 have encouraged social distancing and masks as economies across the United States re-open. Understanding adherence to these guidelines will inform further efforts to reduce transmission. In this repeated cross-sectional survey study, we describe changes in social behavior in Ohio during periods of declining and rising cases. While essential activities remained consistent over time, more individuals attended gatherings of 10 or more people as cases rose, particularly in the 18-29 age group. A majority of individuals wore masks. It appears necessary to continue limiting gatherings and encourage mask-wearing, particularly among younger groups.

In March 2020, Ohio and other states closed schools, workplaces, and gathering spots to limit transmission of SARS-CoV-2. Gatherings of more than 10 people were largely prohibited, and the adoption of social distancing and cloth face masks was encouraged to prevent rapid spread of the virus 1 . As states flattened the curve of new transmissions, they began to reopen. Unfortunately, as restrictions lifted, cases have increased 2 . Understanding to what extent individuals adhered to public health recommendations during reopening can help inform current efforts to shape public behavior and reduce transmission. In this study, we describe social behavior in Ohio early in the re-opening phase and then afterward as cases rose.

This repeated cross-sectional study surveyed adults seen at a large integrated health system in Ohio in the past year and active on MyChart. We excluded patients who tested positive for SARS-COV2 prior to the survey. Patients were sent a 14-question survey via MyChart about social distancing and hygiene behaviors in the past 7 days. The survey was developed based on expert opinion and prior surveys 3, 4 . It was pilot tested for clarity and sent out in seven waves from May 19 to July 24. After an initial lock-down period, Ohio began to reopen on April 30; daily cases bottomed on June 15 then rose substantially; mask-wearing was mandated on July 23.

Survey responses before and after the June 15 nadir were compared using Student's t-tests for numeric variables and Pearson chi-square or Fisher's Exact tests for categorical variables. Secondarily, we compared respondents who stated they "always wore masks" to respondents who wore masks less often to identify if there were other differences in public health behaviors. All statistical tests were two-tailed with a significance threshold of 0.05. Analyses were conducted using R v.4.02. This work was approved by Cleveland Clinic Institutional Review Board.

A total of 654 individuals responded (7% response rate) and were similar in age and sex before and after June 15. A majority of respondents wore a mask outside the home, 53% before and 64% after (p = 0.008). More respondents attended a gathering of 10 or more people after June 15 (19% versus 11%, p = 0.01) ( Table 1) . Mask wearing was less common among those who attended a large gathering than those who did not (34% versus 66%).

Changes in social behavior differed by age group. Public gatherings increased among 18-29year-olds and 30-49-year-olds (by 25%, p=0.02 and 17%, p=0.05, respectively), but not among older patients. Mask usage increased among 50-64-year-olds (40% to 58%, p=0.03). Respondents over 65 had the highest mask usage during both time periods. Activities such as grocery shopping, seeking healthcare, and hand-washing did not change over time in any group (p>0.07) ( Table 2) .

Respondents who always wore masks practiced other protective behaviors. Those who always masked were more often female (75% versus 59%), washed hands more frequently (78% versus 46%) and avoided others in public spaces (51% versus 22%). Respondents who did not always .

In this repeated cross-sectional survey study, we found an increasing percentage of individuals attended large gatherings as cases were rising in Ohio, compared to a period of declining cases. Increased socialization was most apparent among 18-29-year-olds, possibly illustrating 'caution fatigue' amongst those at lowest risk of dying from COVID-19 5 . This behavior has been reported anecdotally in the lay press, but has not been previously documented. While the majority of respondents, especially those over 65 years, used masks, individuals who attended gatherings did so less consistently. Essential activities and sanitization practices remained largely consistent across time and age groups.

A recent review concluded that face masks do not adversely affect hand hygiene 6 . Our study supports this finding, as respondents who wore masks more often followed all public health recommendations.

Study limitations include sampling from a population that has accessed the healthcare system in the past year and may be more aware of public health messaging.

As the national conversation focuses on safe economic revival, it appears important to limit gatherings of more than 10 people and encourage mask-wearing. Messaging should target younger patients, who are also least likely to wear masks.
