4 Possibilities.
1- It is a common flu, without major consequences and they are making a splash for nothing: Some sick people and a few dead.
2- It is a dangerous and severe flu, but governments will be able to isolate infected people and prevent the epidemic from spreading: Same as case 1.
3- It is a severe flu but the laboratories will get an effective treatment in a short time: Same as cases 1 and 2.
4- It is a severe flu, transmitted between humans, without cure and without control of infected people, spread worldwide: Millions will die.
In general, it never reaches situation 4.
