Choose the parasite.
At the beginning, increase your disease drug resistance 2.
Then make the disease transmit by Rodent. You know, where the rats travel?
Try to get rid of symptoms by selling them. This makes your disease invisible and gives your more time.
Then increase resistance against heat to 2 - Madagascar is a warm place?
It is unlikely, that a ship will take the disease from your starting country to Madagascar, so you will have to infect several countries with harbours around the World. So you need to increase the resistance against cold and moisture also at level of two
