Not necessarily some recover, and obviously early stage is hard to spot without a blood test ,what im saying is a rabbit could still have mixy and folk will be none the wiser in the early stages,sometimes the liver can be flecked or light in colour but his could be the start of other things for instance RHD,or if you have a pet bunnie and you put a early stage bunnie near it you will also find out if mixy is presant, ive killed more bunnies than you would think matey so do go on about running them with dog's and being able to spot stuff,been there wore the tea shirt and bra.
