What links coronavirus myths and QAnon?

Online and in real-life demonstrations, two viral conspiracy theories are increasingly coming together.

At first glance the only thing they appear to have in common is their vast distance from reality.

On one hand, QAnon: a convoluted conspiracy theory that contends that President Trump is waging a secret war against Satan-worshipping elite paedophiles.

On the other, a swirling mass of pseudoscience claiming that coronavirus does not exist, or is not fatal, or any number of other baseless claims.

These two ideas are now increasingly coming together, in a grand conspiracy mash-up.
