Plague Inc: How to Beat Bacteria on Normal

In Plague Inc. for the Android & iOS (iPhone, iPad, iPod Touch, etc.), Bacteria is the first plague you have access to. You’ll have to beat Bacteria in order to unlock Virus and keep progressing through the plague types.

I wrote up a very detailed guide on winning your first game on Bacteria, so check that out if you haven’t won a game yet.

Here is the basic summary of the strategy I use to beat Bacteria.

Stage 1

  • Start in China
  • Transmissions: Air 1, Water 1
  • Symptoms: Rash, Sweating, Skin Lesions, devolve any lethal symptoms mutated
  • Abilities: Bacterial Resilience 1

Stage 2

  • Transmissions: Air 2, Water 2, Extreme Bioaerosol
  • Symptoms: Coughing, Sneezing, devolve any lethal symptoms mutated
  • Abilities: Bacterial Resilience 2 and 3, Drug Resistance 1

Stage 3

  • Once China gets around 1.2 billion infected, they will be alarmed and countries will start to fund the cure
  • Symptoms: Cysts, Hyper Sensitivity, devolve any lethal symptoms mutated
  • Transmissions: Bird 1 and 2, Livestock 1, Blood 1
  • Abilities: Genetic Hardening 1 and 2 as the cure starts to build
  • Save about 30 to 40 points for the next phase
Stage 4
  • Most countries will be infected, around 4 billion of the population
  • Symptoms: Immune Supression, Paralysis, Coma (both Paralysis and Coma slow down cure research), only devolve severely lethal symptoms mutated
  • Transmissions: Any you may need, based on the countries that need to be infected
  • Abilities: Cold 1 and Heat 1 if you have extra points, Genetic Reshuffles if the cure starts to get out of hand

Stage 5

  • All countries infected, around 5 to 6 billion of the population
  • Symptoms: Slowly build up Total Organ Failure, Necrosis, Hemorrhagic Shock, Internal Hemorrhaging, you don’t want to outpace kill rate with infection rate  in the last countries infected
  • Transmissions: Only if you have extra points
  • Abilities: Genetic Reshuffles if the cure gets too high

Stage 6

  • Everyone is infected, time to destroy them
  • Symptoms: Throw whatever lethal symptoms at them that you can
  • Abilities: Genetic Reshuffles if the cure gets too high
  • Congrats, you win!

    you are a genius!!! i used to always start in greenland because it’s hard for the disease to get there, but now, i am always going to start in china. thanks!!!

    I recomend getting insanity and dysentery, they completely stop all medical research, but this is like in stage 4 I recommend it.

    Best I’ve been able to do is +/- 500m dead… but then I’m a little slow… Can’t seem to keep up with the rate of infection and before I know it, China’s started on a cure… I’ll keep at it though

    The best way for me is to get everyone infected while devolving and mutations and when everyone is infected you smack them hard with symptoms

    Thanks. It worked for me! The cure was about to be developed, everyone was infected and dying so in a last ditch effort I sold five of my symptoms and got just enough genetic points to buy a genetic reshuffle. Phew! That saved me! From that point on I watched as humanity withered away…

    This guide didnt work for me, Iceland didnt spread too much and ended up killing everyone. Also by the time i was halfway finished with stage 2 stage 3 had occured and basically i was off track and lost :( can you help me what i m doing wrong?
