I'm going to call it a virus, just to give it a name. Say many gov. agencies have this virus and are all working with it to reach some common goal(super solider etc.) The virus matures and become uncontainable and leaks into the air undetected. This happens everywhere at the same time. The virus leaks in the open where it multiplies rapidly. Nobody is affected right away, maybe another incubation period. This would allow time for international travel, assuming that other countries don't have access to the virus.
By this time the virus will have entered the bloodstream of millions of human across the country and world. Then a the virus would undergo another change that would affect the brain and rest of the bodies functions of a small part of the population. Most people wouldn't be initially affected at all. Some people would be affected more that others in the intelligence department. From there, the rest of the population would be changed manually or eaten.
The virus would also start to transform some humans, with a certain genetic code, into something more (i.e. Smart ones, big ones, jumpers).
p.s. if this post turns out with gray font again, I will need help changing that.
