The WHO changed its guidelines on the use of PCR tests on the day of Biden's inauguration.

They now state that a positive result in and of itself does not indicate an infection with COVID19 and that a second test is required along with a clinical diagnosis.

The new guidelines on "Nucleic Acid Testing (NAT) technologies that use polymerase chain reaction (PCR) to detect SARS-CoV-2" from January 13th were updated / published on January 20th.

Documents released on the same day that Trump left office and Biden agreed to pay WHO again.

Falls will magically drop dramatically now. https://www.who.int/news/item/14-12-2020-who-information-notice-for-ivd-users
