Description
Unintended consequences of human behavioral changes induced by governmental and individual responses to COVID-19 risk are yet to be fully realized. Herein, we evaluated changes in outdoor activity patterns during the spring and summer of 2020 vs. 2019 in the Northeast and Midwest United States. We used self-reported data from daily surveys available through a smartphone application, The Tick App. We simultaneously assessed changes in exposure to tick vectors in relation to changes in outdoor recreation. We observed a 30% increase in self-reported tick encounters during the spring and summer of 2020 compared to the same period in 2019, and a two-fold increase in outdoor activities. We observed a shift towards peridomestic activities in 2020; while peridomestic activities doubled after stay-at-home measures were first implemented, recreational activities in green spaces initially decreased and only increased towards when mobility restrictions were relaxed, leading to a 18% increase in 2020. The timing of the initial shift in outdoor activities coincides with COVID-19 stay-at-home orders in the United States, suggesting changes in tick exposure were influenced by 2020 COVID-19-driven behavioral changes. Our findings suggest that public health response should also address competing hazards from COVID-19 related outdoor exposure.
