Plague Inc. | Walk through : Virus

Casual -

Starting Out:

Pick a Starting Country	Pick a Symptom Path	Focus on Infectivity
This is the first step to starting the game. This will affect how your plague acts to different climates, but also how quickly your plague will spread.	Symptom paths effect how your plague interacts with humans. Learn all of the deadly, quick killing Symptom Paths Here.	Infectivity is what gains you more dna points. Don't try to kill people too early in the game. Or else they will have the time needed to finish the cure.
Best Starting Countries:	Click Here - Symptom Manual	Starting Countries Matter
1.       Saudi Arabia 2.       China 3.       Iraq 4.       Indonesia 5.       Mexico 6.       UK	There are the most effective starting countries that I have found. Saudi Arabia is my favourite just because of its mass of airplanes and ships that travel around the world.	If you are having trouble beating a plague on plague inc: ·         Use a better or different starting country ·         Focus on infectivity more until 60% of people are infected ·         Learn your symptoms.

# of infected	|| Walkthrough ||	Transmission:	Symptoms:	Abilities:
1	Start in any country you like. I have made some recommendations in the starting out section above. I usually use Saudi Arabia.	N/a	N/a	N/a
2-30	Pick a symptom path. This is how you will evolve symptoms for your plague. Save up DNA points. So that you can buy a transmission and infect your starting country faster. I start with Water 1. I find it can increase infectivity more than air 1.	Water 1 Or air 1. But I usually start with water 1. If you do use air 1 instead first; buy water 1 in the next step instead.	None Not needed right now.	None Not needed, just like symptoms. Wouldn’t do much for your plague.
31-1,500	Watch your screen for tips. The game will give you news updates and reminders throughout the game. They can be important and game changing during fighting the cure and killing the world. You should have around 15 DNA points by now, invest once again in transmissions.	Air 1	First Symptom Path Trait. I picked the coughing path. But, because the virus mutates a lot I have nausea & coughing.	Still not needed until your plague spreads to a much larger scale. These are important later on in the game.
15,501-100,000	15k - 100k infected took me a couple seconds with: Water 1 Air 1 Coughing & nausea You should now have roughly 11 DNA points. Transmissions will not allow your plague to be detected as they don't effect humans other than increasing the chance of the plague spreading. Keep this in mind. But right now you should invest in drug resistance to help increase infectivity!	Right now you will want to save for more transmissions. During this stage, I find drug resistance to be a good investment.	Don't buy any more symptoms. Because virus mutates more, you will have to DEVOLVE lethal symptoms. This is to not alert the humans.	Drug Resistance 1 This lets your virus survive treatments from basic medicine. This is very effective when starting out.
100,001-5,000,000	Boom! Once you purchase the drug resistance you should see some red bubbles to pop. Your disease should now be in multiple countries. This is a good step. You now have millions infected but still need more transmission! Evolve the trait: Air 2.	Air 2 This will increase the change of your plague being spread by airplanes.	Not yet! Devolve any lethal symptoms for now. This is the reason most people struggle with virus. They aren't aware that the free traits aren't helpful.	None for now.
5,000,000-50,000,000	You should have around 17 DNA points by this point. Congradulations. You have infected over 1% of the world. 50m. Keep an eye on government activities around the world. Evolve water 2 & remember to devolve those annoying, random symptoms that keep popping up for "free".	Water 2 This will increase the movement of your plague through waterways. This helps infect Greenland!	You can keep the less harmful ones. Symptoms can raise awareness of your plague. Isn't good at this point of the game.	These will help stop the cure.
50m-80m	You have been spotted! This is the point the government has noticed the virus. The spread of your plague has slowed down from the 5m-50m jump by now. And they are now aware of you. Keep spreading. Evolve Extreme Bioaerosol to boost your transmission and to infect the still healthy countries.	Extreme Bioaerosol	Keep devolving. Have a question of need help? Leave a comment!	None
80m-2b!	Billions now infected.. Good. You should have just under 80 DNA points that can be used to start the beginning of the end! I continue on my coughing path by purchasing sneezing & Pneumonia. Cold resistance will be effective in infecting Greenland & Canada.		Sneezing Pneumonia	Cold Resistance 1
2b-2.5b	Cure is started. The cure will not have much funding as it has just begun. You will not have to worry about the cure until it reaches 80+ %. Now evolve Pulmonary Oedema. This will once again increase infectivity. Bird 1 and Insect 1 will help to boost infectivity in almost all countries. This will help infect the rest of the healthy population!	Bird 1 Insect 1	Pulmonary Oedema	Heat 1 (if you have extra points you don't want to save)
2.5-4b	You should now have over 100 DNA points. 4 billion is large part of the world. The cure should have less than 5% by now as well. This is the perfect time to become hostile. Evolve: Pulmonary Fibrosis Total Organ Failure Insomnia Rash Sweating With left over DNA points evolve Rodents 1.	Rodent 1	Pulmonary Fibrosis Total Organ Failure Insomnia Rash Sweating	Genetic Hardening 1
4b-6b	By now a country should have started to lead cure research on a global level. Also, your first death will cause countries to worry about how far spread you have become. Pop the blue bubbles! The world leaders will now start to kill off animals carrying your disease and close ports, airports & borders. Now it is a race to see if you can kill before they can cure. Evolve all symptoms you can. But buy a couple transmissions if you have spare dna points.	None	Coma Skin Lesions Seizures	None
6b-7b	Annoying Cold Countries. Buy Cold Resistance 2. Purchase Necrosis to make the dead bodies around the world a source of infection. Purchase as many symptoms to kill as you can.	None	Insanity Necrosis	None, unless cure is 80%+ Then buy: Genetic Reshuffle 1
Endgame	Buy genetic reshuffle to blow the cure off. This will make sure that you will succeed. Continue evolving your virus as much as you can. All symptoms help out at this point of the game. No healthy people in the world - this is one of the last steps to defeating the world.	Insect 2	Internal Hemorrhaging Fever	buy: Genetic Reshuffle 1 & 2
