You can prevent it by doing proper quarantine. Many people quarantine their fish for 2+ months. During this period, many people also do prophylactic treatment. One of my favorite is hypo for 4+ weeks, prazi-pro for a couple weeks, and then a couple weeks of observation.
Fish can live for years. I don't know why we can't wait a couple months before we put them in DT.

That's not usual and surely not any excuse for not doing a proper quarantine. Usually it is quite obvious if there is a disease after 3 to 4 weeks. Of course to be safer is to leave the fish for 6 to 8 weeks, but if there is a disease it is a lot more common to come out after a week to 3 weeks.
