The COVID-19 pandemic has made significant impacts on people’s everyday life. In particular, social distancing, a widely adopted strategy to slow COVID‑19 transmission by limiting contact between people, has changed human mobility and their behavior drastically. While public health social distancing-related interventions such as stay-at-home order, overnight curfew, facility closure, and government ordered lockdowns restricting human movements in general, reopening decisions and non-uniform implementation of interventions can increase human movements and the risk of COVID-19 exposure unevenly in space and time. In this paper, we study how human mobility in our specific area has been affected during the COVID-19 pandemic by focusing on facility closure and reopening in the midst of new lockdowns, restrictions and spikes in infections. We analyzed cell-phone-based origin-destination trip data at the Census Block Group level in County of San Diego, CA. Places of interest within our local region, or destinations, in this study include Universities and popular attractions (e.g., zoo, park, beach, casino). We will discuss how mobility patterns to those destinations have changed before and after closure and after reopening and sociodemographic characteristics of origin places.
