@sillybilly "Normal flue will probably do more damage". Probably will if you get coal dust in your lungs!
A flue is a duct, pipe, or opening in a chimney for conveying exhaust gases from a fireplace, furnace, water heater, boiler, or generator to the outdoors.
Flu is very infectious and easily spread to other people. You're more likely to give it to others in the first 5 days. Flu is spread by germs from coughs and sneezes, which can live on hands and surfaces for 24 hours.
