We need to start thinking more critically about "long COVID"

First, consider that at least some people who identify themselves as having long Covid appear never to have been infected with the SARS-CoV-2 virus. In Yong’s influential article, he cites a survey of Covid long-haulers in which some two-thirds of them had negative coronavirus antibody tests — blood tests that reveal prior SARS-CoV-2 infection.
