Fungus

Pathogen Adaptability

Fungus has the characteristic of being much more effective in wet environments rather than arid ones. Countries such as Indonesia are much easier for this pest to infect, while countries such as South Africa find it difficult to spread in dry climates.

In this particular case, Fungus takes an extra month to reach approximately 6000 cases in an arid country than in a humid one. This video was tested on normal difficulty without the use of genes or cheats.

Fungus is a special pathogen than the other standard plagues, where the DNA costs for some traits are altered such as the Bird transmission, where it is much cheaper than Virus or Bacteria, making these traits much more accessible to the player in order to quickly increase transmission across land borders.

Cross-Country Infection Limitations

Fungus has certain limitations when spreading through different countries, so it is important that the player evolves traits such as Water, Air or Bird, which in this plague the DNA price is much lower than other pathogens. In case the player does not evolve good transmissions, the Fungus outbreak will have much difficulty in spreading in nearby areas even if the country has a large number of infected people.

In this gif you can see that even when the Fungus has a good amount of infected people in Bolivia, as there are no specific transmissions to spread to other places, the disease only stays in the initial country and does not spread to other places in South America.
