Viral infections generally don't last past a certain amount of time, so when someone who is not immunocompromised clearly has an infection past a certain point, it is assumed to be bacterial.
It's also not unusual for someone to end up with a bacterial infection because their immune system is weakened from the viral infection.
Your coworker almost certainly didn't repeat everything the doctor said or did, nor should she have to; mind your own business. It's wild that you were not there, don't posses any medical training, but consider yourself more qualified...
That’s not true at all; you can’t generally distinguish viral infections from bacterial infections by the length of illness. [charitably, this is somewhat a useful rule of thumb for many cold like illnesses, but the GP knew how long they were sick…and Covid is a good example of something some people are very sick from for a long time.]
Why do you think any real expertise is required for a situation like this? It’s a simple reality that medicine, like any field, is brimming with practitioners who do not follow best practices and even many that are not good at their job. Doctors make terrible decisions all the time. I can give you numerous anecdotes in my life where doctors were dangerously wrong even when presented with very clear evidence.
I am a person with a history of pleuro pneumonia. Doctors holding out on antibiotics twice nearly took my life (not exagerating, this was said by doctors)
It's very hard for me to get antibiotics and at the same time I have a high chance of getting nasty bacterial infections with each cold. The last infection 2 years ago has caused me to have a permanent cough. Just wish antibiotics weren't so vilified, they actually serve a purpose. Why can't we reduce use in livestock first?
