Smallpox
Disease Severity
Smallpox is characterized by a high number of severity unlike other pests, making it easily detected in the first stage of the game. Although, the player has certain aids to prevent the world from panicking easily about the disease and trying to eradicate it at once, in this case the solution is White Pox, which allows to partially reduce the severity and a little bit the lethality of the disease, making the world population not to worry so much and giving the plague more time to spread without causing so much panic, which will cause the closing of borders and airports/seaports.
