Choosing A Symptom Path | Symptom Manual

2. Choosing a Symptom Path

---

Now you must choose your symptom path! There are 6 total paths you may take, the path is usually decided by the first symptom you buy; and are named after the first symptom in the "path of traits.

If you buy Nausea first, it doesnt mean you use the "Nausea Path". The path you use, you decide by the amount of traits you have bought. If you have 4 traits from the Coughing Path, but started with 2 Rash Path Traits, 3 Insomnia Traits, and have cysts; 

you would have started with the Rash Path of traits but now are following the "river" or path" of Coughing.

About Bacteria:

 

The bacteria Plague, is the first plague you have access to on Plague Inc. 

As stated on the game itself, Bacteria is the most common cause of Plague. Unlimited Potential.

---

1.  Starting Out. -  (1/10)

Picking A Starting Country -

For Bacteria, China, Iceland & Saudi Arabia are some of the best places to start.

China is the overall best for Bacteria.

This is because of the amount of people that live in China. A large amount of the world's population calls China home, the size of the country allow you to gather DNA points faster.

Starting in China; early on in the game, is one of the fastest ways to evolve quickly and infect the world much faster.

Iceland works well, if you are more patient. It gives your bacteria the ability to thrive in cold temperatures but also allows easy ship-transmission to Greenland.

2. Help your Plague Spread!

Evolve coughing, cysts & rash to increase the infection rates of your plague.

Early on in the game, symptoms are a good investment overall and key to your disease spreading as well.

Now buy the transmission 'Air 1'

 Air 1 is very important, it allows your disease to spread faster but also allows sweating and hypersensitivity to infect Canada, Greenland  & Russia much faster.

Cold Climates are the hardest to infect and kill with bacteria.

3. Spreading & The Cure

Your bacteria should be conquering China by now. China is a neutral country, not hot or cold climate. Right now, your DNA points should skyrocket as people become infected.

This momentum is important but hard to get out of China sometime. When starting in a new country your disease will spread very, very slow until it has begun to infect a larger population. If you cannot infect people fast enough, the cure will effectively stop you and the game will end in defeat. 

To keep infecting enough people to sustain momentum buy
Air 2
Drug Resistance 1
Drug Resistance 2

China will have noticed your disease by now. Stay away from aggressive symptoms and focus on spreading to different countries.

Infectiousness is your main concern at this point of the game.

Aggressive Symptoms shouldn't be purchased before the world is focused on a cure; so that you are able to spread and not scare the world into controlling your spread.

4. Unlock Lethal Symptoms & Watch Infection

Buy the following symptoms:
Sneezing
Sweating
Fever
Skin Lesions
Necrosis 

Sell fever after purchasing Skin Lesions or your disease could kill too quickly, slow infection and cause more funding to research to a successful cure.

Skin Lesions increase infection rates effectively while Necrosis kills those infected but also allows dead bodies to transmit disease which also effectively increases transmission.

Right now your disease will be considered "potentially dangerous" but will not be too lethal in the eyes of governments... yet.

5. Infect Different Climates

If your disease is having trouble infecting:
Africa
Middle East
Buy:
Livestock 1
Blood 1
Insect 1
If your disease is having trouble infecting:
Europe
North America
Buy:
Rodent 1
Cold Resistance 1
Water 1

6. Greenland, Mexico & Other Small Islands

Small islands can become the most annoying part of the game. If you don't infect island countries and all seaports are shut, there is almost no way for your disease to infect the healthy country.

To infect:
Greenland & Iceland
Buy Cold Resistance 1
Water 1
Water 2
Sometimes your disease will spread too slow in these countries. To stop the slow spread to stop you, buy
Cold Resistance 2
Air 3
Mexico
Air 3
Water 1
Water 2
New Zealand
Heat Resistance 1

6. When All Countries Are Infected

You are now unstoppable right?!

Wrong.

Cure research is most likely becoming an issue. Right now you have to infect the entire world population and kill them before they can kill you.

Don't kill too fast before everyone is infected or human efforts will increase to protect the healthy from your pathogen.

Now, to slow cure efforts buy:
Insomnia
Paralysis
Seizures
Genetic Hardening 1

7. Kill and Stop Research

The symptoms you purchased in part 6 will slow cure research efforts but also increase the lethality of your bacteria. 

Right now you don't want to kill all of your hosts until the entire population is infected.

To slow cure research even further but not increase death rates buy:
Genetic Reshuffle 1

8.  If The Cure Is Coming!

If the cure reaches 95%, invest in
Genetic Reshuffle 2
If infection rates are too slow, invest in
Water 1 & 2
Insect 2

9. There Are No Healthy People Left In The World

When there is no one left uninfected you are free to destroy humanity!

Keep in mind you still must kill billions of people before the cure is successful and finished.

The most effective way to kill quickly is to buy
Total Organ Failure
Fever

10. Success!

If the cure reaches over 95% buy
Genetic Reshuffle 2
Genetic Reshuffle 3

Success! You now have destroyed humanity!
