Yeah GPs are so dumb. Get your medical advise off a BB forum or even better get your own google degree.
I would bet there isn't a GP in Australia that believes antibiotics kill a virus. But they do prescribe them for suspected viral infections sometimes for a few reasons. Pressure from the dickhead patients who demands antibiotics because they think it cures a flu.
At risk patients. Someone sick with a virus is much more susceptible to bacterial infections.
