Spoiler alert!
If you read this, you will get an extermely helpful tip.
Bring visibility to zero. up resistances etc to increase infectivity with no visibility. wait until all countries are infected, then start upping lethality and infectivity (fever is good for this) once everyone is infected (happened to me att day 85) then Kill em all!!! if you wait long enough, you will have enough points to buy everything, do, exept only human. that's how i won.
