Wikipedia:Articles for deletion/List of fatal diseases
While it seems like "dead" would be easy enough to identify, no reasonable definition for "diseases that cause death" will ever exist.  There are hundreds of conditions that might, and might not, qualify as "fatal diseases", depending on resources, treatment, and comorbidities.  There's no evidence that any |reliable source finds this to be a particularly important characteristic for classifying diseases; creating this list is essentially riginal research.  "Disease", in particular, is a complicating factor, since several of the most significant causes of death are not properly "diseases" (e.g., trauma).  Do you exclude tobacco use, which kills millions each year, but include a genetic disorder whose effect on lifespan can only be determined through careful statistical analysis of the affected population
