No lockdowns or school closures are necessary. But research into the disease generally referred to as "Long COVID" needs to be increased. A recent Nature Medicine review this week found that at least 400 million people worldwide have been afflicted with Long COVID resulting in an economic cost of $1 trillion.

Not much is known about Long COVID. In fact, scientists and researchers have identified more than 200 symptoms they believe are associated with Long COVID but aren't sure what the underlying pathology is. Yale researchers identified proteins in patients suffering from many of the major symptoms of Long COVID. But there's no test nor is there a treatment for Long COVID.
