LOS ANGELES - Social distancing has decreased dramatically since the spring, and the states that largely haven’t adhered to staying six feet apart and wearing masks are being hit the hardest by COVID-19 surges, according to a large survey.Researchers polled 139,230 individuals across all 50 states between April and November 2020 and found a general decline in social distancing over the summer and into the fall.For example, the percentage of people saying they have been in a room with people who are not members of their own household in the preceding 24 hours jumped from 26% in April to 45% in October.RELATED: US COVID-19 deaths top 3,100 in single day, hospitalizations reach record 100KLarge group activities have particularly jumped in.
