I'd question tht in the case of diseases... the disease gets frozen also, so it can't get worse. If we freeze a large group of people some will live and some die... which helps with the problem of 'charicter bloat'. This being the condition where the cast is so large it squishes the story till it can't move at a good clip and either you reduce the cast through removing or ignoring the charicters or lose a large portion of the audience to confususion or them not wanting to put the effort into keeping up with the series.
Which brings me to another separate section... story killers. Over large casts. Harems that diserve their own zip code. Jumping the shark. Adding in bards with names able to be shortened to 'TB', rather like a disease.
