As states across the US continue to see a decrease in fevers during the coronavirus pandemic, Florida and Maine are seeing upticks.
Kinsa Health, a medical technology company based in San Francisco, has been tracking daily fever readings using data from smart thermometers connected to the Internet.
According to one of Kinsa's maps, which tracks 'atypical' illnesses, most counties across the nation are colored yellow, orange or burnt orange to indicate low, mild or moderate rates of illness, respectively.
But Florida is the only state to have counties colored red, which indicates 'high' rates of atypical illnesses.
It comes on the heels of the state's Republican governor, Ron DeSantis, issuing an order for all residents to stay home after weeks of pushback.
In addition, on a map showing whether illnesses have been increasing or decreasing over the past week, almost every county indicates a decrease - except in Maine, where the majority of counties show an increase.

Kinsa has distributed more than one million thermometers and get about 162,000 temperature readings a day.
The thermometers upload the temperatures to a database (similar to Apple iCloud) and users can add other symptoms into an app.
Prior to using the tool to track COVID-19, Kinsa's tool has mostly been used to track where seasonal flu outbreaks are occurring.
Traditionally, the company's predictions have been two or three weeks ahead of those compiled by the Centers for Disease Control and Prevention.
With the coronavirus pandemic a new feature has been added to the map, which the company calls 'atypical' illnesses.

This tracks illnesses that don't match up with typical flu patterns and are likely due to the novel coronavirus.
