To identify clusters of coronavirus infections, Kinsa recently adapted its software to detect spikes of “atypical fever” that do not correlate with historical flu patterns and are likely attributable to the coronavirus.

As of noon Wednesday, the company’s live map showed fevers holding steady or dropping almost universally across the country, with two prominent exceptions.

One was in a broad swath of New Mexico, where the governor had issued stay-at-home orders only the day before, and in adjacent counties in Southern Colorado.

The second was in a ring of Louisiana parishes surrounding New Orleans, but 100 to 150 miles away from it. That presumably was caused by the outward local spread of the explosion of infections in New Orleans, which officials believe was set off by crowding during Mardi Gras.
