Four years in, Long COVID is leaving its mark on the U.S.

Last week marked 4 years since the WHO declared COVID-19 a pandemic.

On the bright side, this means that some people are recovering from their Long COVID symptoms. On the other hand, many are not, and with such a high percentage of impacted patients, the burden on the healthcare system and American life overall is not to be scoffed at.
