The 1918 flu or the Spanish Flu infected 500,000,000 people (500 million) and 50 million people died.
It is conjectured (but not confirmed) that 'cytokine storm' might have played a factor in this flu/virus in 1918.
Basically, 'cytokine storm' is when the body's immune system attacks the body by 'over reacting' to an infection.
If I start getting sick, I might take aspirin and benadryl to suppress part of the immune system.
The 'cytokine storm' is because the immune system is 'too powerful'.
Of course, an anti-viral would be good as well.
The 'cytokine storm' may be happening now with our existing flu outbreak. There have been over 100 children reported dying from the flu.
Where I live, a 10th grader came down with a respiratory illness, and then died later the same day.
I believe the 'child' was very healthy, and may have had the 'cytokine storm'.
It is possible that China is having this trouble with the new Corona virus outbreak that started in Wuhan, Hubei Province, China
Aspirin might be contraindicated in a cytokine storm.
