1) Pick Virus. 2) Start in any country with an airport or seaport, or madagascar. 3) Sell starting symptoms (if any), other than sneezing . If you don’t have sneezing, buy it and airborne transmissions. 4) Buy 1-1-1-0 resistances. 5) Once your disease spreads to 3 countries, sell sneezing to get rid of visibility. 6) Wait until all countries are infected. If Madagascar closes or this is after day 30, restart. (took me many, many times) 7) Buy all 4 Drug Resistance and buy sneezing, coughing, vomiting. 8) After a few days, unlock tier 2-3 keeping whatever symptoms it gives you. 9) Buy fever, fatigue, diarrhea, pulmonary edema, hypersensitivity, and hemorrhaging. 10) Wait until everyone dies. Copy and paste this! keep it alive!
I did not take hemorrhaging but instead went for water resistance 2 and waterborne, since everything was flooding.
