Can/Should I Get Another Cat?

[Travis13g]

About 2 years ago me and my brother both got a cat. Everything was fine until after about 9 months my cat got sick and unfortunatly died of FIP (Feline Infectious Peritonitis) and as it turns out my brothers cat was the carrier of FoCV (Feline Coronavirus) and gave it to mine which develped into FIP. Its a year later and i was wondering will my brothers cat ever not have FoCV? And if not would it be a bad idea for me to get another cat anyway? Would the cat die like my first one or might it be different this time around?
I would really aprecciate your opinions/answers because im very conflicted right now. I want another cat but i just would just feel so guilty if i got another cat and it died because i was foolish.
