COVID-19 came first to my metropolitan area. Washington State confirmed our country's first case of COVID-19 Tuesday, January 21st, 2020.
In early March, I realized CDC's maps didn't reflect cases each state was reporting, nor were any historical data available, so I started making my own maps based on data published by each individual state.
I record each state and territory's numbers around 9 p.m. Pacific every night. Instead of using CDC's scale, I used a doubling scale, where states change color when they've doubled from 1-2, 2-4, 4-8. This gif tells the story of how the disease spread through our country and its territories.
It's worth noting that many states did not and still do not have enough tests to confirm diagnoses. And epidemiologists stress that many infected people are asymptomatic and will not be tested. These maps track ONLY confirmed cases.
