You are right, most people die from Flu related complication when they have other heath issues.
The Coronavirus is most likely causing flu related complications leading to deaths in China and other places.
Can pneumonia be a flu related complication?
Sorry I have lost a 82 year old Aunt to Flu related complication. Also lost my Great Uncle/Aunt to the Spanish flu back in 1920, most likely flu related complication.
I am sure a flu related complication will take my wife out too, she has ACC in the windpipe. That is why the Doctor insist on her getting the flu and Pneumococcal shots each year. Bet you never heard of ACC too?
Off to take my Cold medicine.
Influenza can cause pneumonia on its own. It’s called, quite appropriately, influenza pneumonia.
