As the U.S. and much of the world hunkers down to slow the spread of the novel coronavirus, some virus-related conspiracy theories are having a heyday. Specifically, a conspiratorial false claim that 5G technology is linked to COVID-19 gained ground, accelerating from obscurity into the rattled mainstream by way of conspiracy theorists who’d been chattering about 5G conspiracies for years.

While there is scientific consensus around the basic medical realities of COVID-19, researchers are still filling in the gaps on a virus that no one knew existed five months ago. That relative dearth of information opens the way for ideas usually relegated to the internet’s fringes to slip into the broader conversation about the pandemic — a dangerous feature of an unprecedented global health crisis.
