US drops PCR test for Covid-19

As of first January 2022, the US health authorities have stopped using PCR tests because of their inability to detect subjects infected with Covid-19.

This test was designed to spot the presence of genetic material from certain viruses, but not to identify it. The test can detect influenza just as well as Covid-19 or any other infections, but it cannot defferentiate between them.

This is why, in 2020 and 2021, the health services reported very few people with influenza and an overwhelming proportion with Covid-19.
