As you can see from the New York Times’ examination of travel patterns in the United States, there has been a wide and largely regional disparity across the country in terms of who was quick to self-isolate and who wasn’t. Most of New England, the Mid-Atlantic, the Upper Midwest, and the West Coast had issued stay-at-home orders by March 27. Other states that were proactive include New Mexico, Colorado, Idaho, and Louisiana. The urban areas in Texas tried to be proactive even as their state government opposed them. The South, as a whole, did not instruct people to stay at home and the result is that their travel patterns remained normal, or close to normal.
This is going to matter later.
The inconsistencies in policies—and in when they are imposed—may create new problems, even for places that set limits weeks ago.
“Let’s assume that we flatten the curve, that we push transmission down in the Bay Area and we walk away with 1 percent immunity,” said Dr. George Rutherford, a professor of epidemiology at the University of California, San Francisco. “Then, people visit from regions that have not sheltered in place, and we have another run of cases. This is going to happen.”
