Unfortunately, Softie, you are correct. Here is my understanding of Mareks.
Mareks is a virus, so treating with anti-biotics will help with any secondary infection, but will not assist in the animals recovery from the disease. I have found, however, my birds rarely appear ill when they collapse, star gaze or lose the ability to walk. You can vaccinate for it, but (now, I believe one person who talked to me about it was briarwood, but I could be wrong) some people have done small on farm tests of thrivability with and without the vaccine side by side, and found the vaccine wasn't for them. From further reading on other forums, results are very iffy.
Mareks can be contracted by purchasing infected stock, introduced by your boots if you've been in an infected area, and brought in by wild birds. It is shed freely in bird dander, which is unavoidable. If you have it and have not recently introduced new birds or been to another farm/show, then it's highly probable that you contracted it from the wild bird population. Unless your birds live in a bubble, literally a bio-containment bubble, you'll always run the risk.
In the third generation of hatching and introducing birds, I have noted a noticeable difference in flareups, and they have lessened significantly. I breed for resistance, NOT immunity, because I personally feel survivability is a more significant trait than immunity at this point in my breeding program. If I note a bird with symptoms, it's not sold, it is kept here in the farm or culled for the pot when it is old enough. Since introducing turkeys, I had a flare up of 3 birds (out of, currently, around 100) and I'm only looking at losing one, but giving him the fighting chance.
Turkey's carry a non-infections, similar virus naturally in their systems. Exposing the birds to turkeys is similar to the vaccination process. It'll weed out the week really quickly because, since its not actually an infections virus, the exposure causes an immune response. They'll often get sick or show symptoms soon after their exposure to turkeys, and it helps to figure out what you will do.
If you buy at sales or auctions, it's practically unavoidable and, if someone 'as the crow flies' has it on their farm, it's probable you'll end up with it.
It took me a year, to gain a favorite rooster and have to put him down due to Mareks. It hardened me, a little. I learned I had boundries of where I was willing to be a sap and give them a chance and where I thought their life quality had become so minimal that it was cruel to keep them. I drew that line at being unable to feed and water themselves, and losing the ability to protect yourself from the pecking order. You have to decide where your lines are, and thats a decision only you can make as it has to feel right for you.
