A realistic explanation of a typical Plague-inc "infect everyone before you start killing them" strategy

In Plague-inc the most typical strategy is trying to infect everyone, while staying hidden by not harming infected people (when a virus, bacteria, fungus is found, people start working on the cure). Once everyone in infected the epidemic starts to kill.

However, because it is a game, it has some "advantages":

1. A human player:
   He knows that he has a strategy to execute. The strategy may be quite strange, like infect everyone without causing them any harm so 'they' cannot find him. Once everyone is infected he evolves lethal symptoms to kill. The effect of this strategy is to maximize his goal: infect, kill. Stay hidden while infecting 'them' would give him a head start, as 'they' are not working on the cure until he gets into the 'kill' phase.

2. Full environment data is exposed.
   The player knows how many of 'them' are left. He knows if anybody or a region is not infected yet.

3. A specific goal: to kill all people, not to survive (as a virus). Kill all hosts also means a virus (or anything else) would not survive, because they are parasite.

In reality, those advantage may not be fully available.

Thus, I would like to ask if there are any realistic explanations for the case of a disease (virus, bacteria, fungus) executing the strategy "infect all before you start killing them". In this case there are no human (or alien sentient) monitors directly.
