The flu. Did you know almost every animal in the world has its own flu but at the start only birds had the flu but now even snakes have their own flu. Now there’s a new flu called swine flu.
It started in mexico when a pig had pig flu and then got bird flu. The two viruses merged and created a new kind of flu in the pig. After that the pig was infected with the new flu and then caught the human flu. As you might have guessed the two merged and created the deadly swine flu. the pig was then kept near humans and then they caught the swine flu. Humans are vunerable to the flu because the cells are so different in swine flu to normal flu that we over heat and cough unbearably.
I think that if we can keep most people like immigrants out of the country that are affected by the virus we can keep away they virus. Also since airports have started getting some heat responsive cameras that can sense up to half a degree in temperature celsius.
