These are up-to-date values for Rt, a key measure of how fast the virus is growing. It’s the average number of people who become infected by an infectious person. If Rt is above 1.0, the virus will spread quickly. When Rt is below 1.0, the virus will stop spreading

I check this site every day, sometimes twice a day. Hawaii spent several weeks as #1, I am glad to see they have now fallen below 1. Whereas the rest of the country is generally getting worse. My oldest child has a degree in microbiology and pointed me to this site. She will not join groups indoors until the rt for our area is below 1. Her sisters have both had Covid tests. One because of exposure to a coworker that tested posititve. The youngest because she has been running a fever this week. Both have gotten negative test results.

Knowledge is power, protect yourselves.
