How? I wanna know the secret to getting 4 strains in one pandemic. I mean it lasts only 2 weeks basically right? how is that possible?

The 8 stage strains take approximately 3-4 days to progress all the way through. If you get infected within a couple hours of the event starting and continue getting infected with a new strain like right after each one ends, it's possible to get 4 strains. As long as you get infected with before the event ends, it will continue progressing even after the event.

thank you, my math was off. I thought it had to be 8 days for 8 strain ones^^; Good now I can get the three I want:3

Yeah, you should have plenty of time to get at least 3. Have fun! :)

thanks, you too!:D
