That is terrible. It makes me wonder if they actually diagnosed the causative agents. There has been a co-infection that hit my immediate family and extended a few weeks ago. Symptoms presented as a flu-like virus (non-influenza), but also a bacterial infection developed. My kids and wife needs antibiotics to clear the bacteria after the virus cleared. Had a cousin develop bacterial pneumonia as well after the virus.
In all 3 cases, physicians missed the bacterial in the initial, each was told the virus would clear in 5-7 days and on the 2nd trip the bacterial sinus ear or lung infections showed.
Typically, it should be rather straightforward to diagnose a viral vs bacterial infections, but based on personal experience this season and unless Aschoff had complications from influenza induced pneumonia, these co-infections are nasty this go around.
Be careful with your health folks, particularly if a routine “flu” isn’t clearing up after 5 or so days.
