It's so embarrassing to have last year's infectious disease, when
all the cool kids are getting the next big thing, which is
currently the Monkey Pox. Which even sounds like the sort of
disease that fun people might catch.
So, this service would have a small but viable sample of
pathogen
couriered around to your address in a refrigerated
container, with instructions on how to self-infect.
Nowhere would the service explicitly claim to cure your existing
condition - magical thinking in the target market would just
assume that it did.
Just because you're isolating, doesn't mean you have to feel left
out!
