My ex-husband’s brother, 63, died suddenly 2 days after Christmas. He had the flu, developed pneumonia and died a day after seeing a doctor and starting antibiotics. Up until then he’d been active in the community and in decent health. I doubt well ever get an accurate number of flu related deaths.
IIRC This administration has prevented the CDC from giving accurate locations and numbers on Flu since at least 1009
The flu deaths are reported to the CDC, as are deaths from most causes. While it's hard to get an accurate count, statistical methods do help to get a count that is at least within the ball park. Every week, I read CDC's report.
Flu is a tough one. If it doesn't kill you outright, it can make you more susceptible to a secondary infection that can kill you.
I'm sorry for your loss.
