How did the bird flu become an epidemic?
You should understand that flu pandemics can be very dangerous. In WWI far more people died of the "Spanish" flu than in battle. Most flus are only fatal to the very young, very old, or those in poor health. The Avian flu can kill healthy adults so if it were to become widespread it could cause millions of deaths like the Spanish flu before it (turns out the Avian flu is related to the deadly Spanish flu). So far this flu has been contained and casualties limited but it is still something to be closely monitored.
people ate the camtainated bird or got it from the family cause it can spread like the flu or cold!
Most prolly by birds pooping on crops and eating them or people eating contaminated pultry
