Friend was told of a Covid-19 case confirmed in New Haven on Wednesday morning, Feb. 26. The reason I bring this up is because this person was not reported as part of official CDC U.S. case count on Wednesday. It seems to be proof the U.S. numbers are not accurate.

FYI, the CDC website says

COVID-19: Confirmed Cases in the United States*†
† Numbers closed out at 4 p.m. the day before reporting.

From what you wrote, I see no evidence that "the U.S. numbers are not accurate", much less "proof".  The numbers may be slightly out of date (up to 3.5 days), but that is documented.

Added: WHO's sitreps of COVID-19.
