Not a doctor but I know some- Viruses are notoriously hard to diagnose because they don't culture. Some big academic hospitals do have a virus panel where they use brute force PCR assay akin to many Covid-19 tests targeting different virus but they are very expensive hence not broadly available. Community hospitals will have the same diagnostic experience you have. At most they might be able to test for Flu or Covid but that's about it. Another reason is that even if you test positive, there is very little the hospital can do. For the most part, just tell the patient to rest and take Tylenol/Ibuprofen. The anti-virals are just limited to Flu and Covid.

  The anti-virals are just limited to Flu and Covid.

There are also antivirals for Herpes simplex and zoster, HIV, Hepatitis B and C and probably others that i don't know about. It's still a small arsenal but it not limited to Flu and Covid.

Good to know. I'm repeating what an EM doc told me available in her community hospital i.e. they only have Tamiflu and Paxlovid, which is why even if she did have access to Viral panels, they couldn't do anything more to treat those other viral infections.

This. There are a lot of antivirals out there.
