Public health officials needs to adapt to the latest understanding and work with data and statistics accordingly. It’s extremely boring and un-sexy (i.e., it’s not like scientists in the movies making a sudden breakthrough), which is I suppose why so many jump to conspiracies. We crave clear and spectacular reasons for the things we fear and have no control over.

If scientists don't know what is causing "Long Covid", then they don't know what is causing "Covid". Yet, many treatments have been developed for Covid.
If we accept our ability to treat without full knowledge of origin, then "Long Covid" can be treated, as has been done for Covid.
If "Long Covid" deserves a different status due to unknown origin, then the same standard can be applied to the unknown origin of Covid.
disclamer: IANA scientist or doctor, but it looks like long covid might be very similar to allergy (and similarly treated)
