Gaining DNA points does not end the whole game, and you have to pump antibiotic resistance, disease skills, combo abilities, symptoms, increase lethality. From this point on, you begin to infect people in other countries that are across the ocean or a decent part of the land from a primary source. If your disease was transmitted exclusively by airborne droplets, then it's time to add a method of infection "through pets" or "drinking unfiltered water." Interaction with insects, birds is also pumped separately. Panic is instilled in people, and they begin to follow all the doctor's recommendations. The gradual increase in the number of cases leads to death. Starting in the USA, the growth rate will be minimal. For example, if we start from Africa, then our disease will quickly reach Asia and Europe, but they will begin to fight it immediately when it reaches the First World countries.
