(CNN)November isn't even over, and the US has already seen more new Covid-19 cases than any other month of this entire pandemic.
More than 3 million new cases were reported between November 1 and 22, according to data from Johns Hopkins University. That's about a quarter of all US cases since the beginning of this pandemic.
Yes, testing has increased. But it hasn't kept pace with the rate of new infections.
As of late last week, the number of daily new cases increased 25% compared to the previous week, according to Johns Hopkins data.
But the number of new tests increased only 14.55%, according to the Covid Tracking Project.
And in 44 states, the percentage of positive tests is higher than the recommended 5% threshold.
"If a positivity rate is too high, that may indicate that the state is only testing the sickest patients who seek medical attention, and is not casting a wide enough net to know how much of the virus is spreading within its communities," Johns Hopkins said.
And every surge in new cases leads to more hospitalizations and deaths in the following weeks.
