"Don't fix what's not broken."
"If it's not broken, you haven't tested it enough." -- SilverRey
If it ain't broke, don't fix it.
If it isn't broken, test it some more. -- Conflicting Human Axioms.
Some things need fixing before they break. Emergency services anticipate even the ridiculous emergencies so that they can be ready before they happen. This has lead to the 'zombie plague' and 'black hole' plans in the emergency systems all over Alliance space.
Zombie Plague has been on the books in Terran Emergency Systems since before the Shattering. As an emergency plan goes, the forces of entertainment have created an imaginary monster that covers all potential pandemic precautions. Those, of course, including the need for isolation, containment of the infected, tracking and monitoring of infections, proper hygiene and decontamination procedures... the list goes on.
