The four counties in the United States that haven't reported a single COVID-19 case as of Oct. 16 are all sparsely populated and geographically isolated, according to ABC News.
Those counties are:
- Esmeralda, Nev. (population: 981)
- Loving, Texas (102)
- Skagway, Alaska (1,061)
- Kalawao, Hawaii (75)
While the counties point to their small populations as a strong deterrent of virus spread, local officials also described the vigilance exercised by residents and local healthcare providers to keep their counties free of COVID-19, including revised voting procedures for the election, limited gatherings, masking, social distancing and — for Skagway — a significant level of testing given its remote location.
