This seems like it was the pilot for a television series that never got picked up. Lots of tv shows in those days had lead characters that traveled around the country going to new towns, having adventures with locals. The Fugitive was probably most famous one, but also Route 66, Have Gun, Will Travel and "Then Came Bronson" which starred Michael Parks, who stars in this show as a dedicated public health doctor. There are just so man6 public health emergencies though, and rabies and anthrax were in this episode. What next? Plague in Arizona? Venomous snake bite in TX? Tularemia in Tulare?
Michael Parks used to be called "the poor man's James Dean." After Dean died, Parks' slightly look-alike face got him more than a few tv roles. He proved to be difficult on the set of Then Came Bronson (plus the show's premise - anti-establishment loner traveling from town to town helping people solve their problems - was well past its due date by 1970. Pa4ks disappeared for a few decades then was resurrected by young male movie directors as a sort iof cult figure.
So if you want to see Michael Parks as a young man, here's a chance for you to do so. In a few years time, Marcus Welty MD would be on tv and James Brolin would take the role of the angry young anti-establishment doctor ....and he got to chase his patients around town on a motorcycle, to force medical treatment on them. If only they'd given Parks a motorcycle for this episode he might have had a long running tv series.
