The U.S. stands at just over 10 new COVID-19 cases per 100K population per day, up 15% in the past seven days. In the Northeast region, cases are rising at a steady 40% per week.
The CDC came out with another month of seroprevalence data. As of January, there was still no evidence of any increase in the number of unreported infections. As of January, that analysis showed 1.9 actual infections for every one that had been reported. That was actually lower than in prior months. Either a) January was too soon to start seeing those missing infections, b) post-infection antibodies fade fast enough that the seroprevalence survey itself is missing the earliest infections now, or c) something else is preventing those infections from showing in the seroprevalence data.

Here are a couple of previous monthly readings, for comparison. More-or-less, the CDC seroprevalence survey has always shown that there were two true infections for every one reported, plus-or-minus.
