Nothing about long Covid adds up. Consider prevalence rates: How could one study find it affected 3.3 percent of the population of the UK but others an alarming 51 percent of South Americans and 86 percent of Egyptians? Or treatment methods: The BMJ’s systematic review of ways to treat long Covid lists two as supported by moderate evidence, cognitive behavioral therapy and physical exercise. But if you attended the third annual Long Covid International Conference in Boston, you’d think the BMJ was encouraging medical malpractice. During two days of presentations, the world’s leading scientific authorities brought up exercise only to warn against it. Cognitive behavioral therapy received just one mention: “not recommended.” Then there’s the scientific progress, or lack thereof. Six years since the height of the pandemic, the scientific community remains baffled by long Covid. Researchers still don’t know why some people’s symptoms persist or worsen after the acute phase of SARS-CoV-2 infection has passed. Almost $2 billion and half a decade of international effort have yielded little more than hypotheses about micro blood clots and spike proteins and mitochondrial dysfunction. There isn’t a single approved pharmaceutical treatment, not even a test to verify the presence of the illness. All of this is very strange. Stranger still are patients’ stories of astonishing recoveries from severe long Covid, achieved entirely outside mainstream medicine. The stories are connected to a growing community of doctors, therapists, and self-styled coaches who insist the riddle of long Covid has been solved. Like so many health gurus, they offer a solution that depends, in part, on your faith in the process. The solution also works for a remarkable variety of ailments—classic red flags for “holistic” pseudoscience and medical charlatanry. If the stories are to be believed, they represent a neglected approach that demands urgent attention. If not, a colossal medical scandal is operating openly, exploiting sick people desperate for answers and relief. So which is it? Tap the 🔗 in bio to read the full story. 🎨: Yi Hsuan Lai; Getty Images
