Every county in America has reported at least one case of Covid-19 — except for some of the smallest and most far-flung places in Texas, Nevada and Hawaii. The reach of the virus into rural and urban counties alike shows how the pandemic, once concentrated in metropolitan hot spots, has now left few of even the most remote communities untouched as a third surge of infections has firmly taken hold.

Only three counties in the 50 states have never reported a Covid-19 case, according to a New York Times database — Esmeralda, Nev.; Loving, Texas; and Kalawao, Hawaii, a former leper colony on the island of Molokai. (County-level data is not available in some parts of Alaska.)

Two of those are the least populous counties in the nation: Kalawao, with 86 residents according to 2019 census estimates, and Loving with 169.
