It kind of seemed like a nonsequitur to the hungarian thing. But that article did not state there has been a policy change in terms of how cdc is counting cases or whatever. Its well known (in medical circles anyway) that that pcr test was testing positive for people that did not have enough virus to get an infection— trace amounts. The danger is that a bunch of people who test positive without being sick actually think their “immune” because they fought the virus off, when they didnt.
