Fort Wayne, Indiana, is urging people to fight the loneliness of isolation by going out at 7 p.m. and waving to their neighbors.
"Now is the time to look after one another, even from a safe distance," the city said on Facebook on Thursday.
Other cities around the county -- including Grand Rapids, Michigan, and Sandusky, Ohio -- are joining the neighborly wave movement to help communities feel united.
Nearly a third of the world's population are living under coronavirus-related restrictions.
To stop the spread of the coronavirus pandemic, which has so far topped more than 580,000 cases globally, health officials have instructed the public to practice social distancing. This includes staying home, avoiding crowds and refraining from touching other people.
As many continue weeks, and possibly months, of socially isolating at home, it can start to feel quite lonely. But the entire world is in this fight together -- so go outside and say hello (a safe six feet away!).
