I'm a medical professional. It appears that there isn't a way to get antivirals other than asking the doc for them. I don't trust that in a viral pandemic, that it will be accessible, and I am not going to a clinic in the midst of a pandemic to get it. To be honest, I am surprised that the Fishmox stuff is legal, but, since it is, might as well get it.
What irks me is they feed this stuff to animals in CAFOs making resistant germs, but for humans, you need several doctor visits to get the darn antibiotic you need. I just had a dental infection and getting that penicillin was like 'pulling teeth' no pun intended.
If any one knows of a substitute, let me know. Antibiotics are good, but antivirals are very helpful too.
I assume people are keeping an eye out on H7N9 avian flu right now. If not, I suggest a google of it. Also Novel Coronavirus is up to 17 known cases. I think NCoV is a slow mover, but, I am not sure what is going on with H7N9. That one looks to be a bit of an unknown.
