Clear results elusive in long COVID studies

• Funding from the U.S. and U.K. has largely gone toward research characterizing the condition, rather than treatments, he said.

Be smart: Long COVID has proved to be a difficult disorder to define, prompting researchers to repurpose older drugs developed for other conditions.

• Studies struggle to even pin down how commonly it occurs.
• And doctors have been baffled by how it behaves.
• "We've ended up seeing a lot of patients with mild or moderate, mostly stay-at-home infections that came in with a wide range of symptoms. It was bizarre," Bradley Sanville, a pulmonary and critical care physician who is part of the UC Davis Post-COVID-19 Clinic, told me this spring for an Axios Deep Dive about long COVID.

The bottom line: Even so, researchers do appear to be narrowing in on the pathology underlying long COVID which could ultimately lead to more researchers launching new trials, Ledford writes.
