There is no disease with a 0% survival rate. Even the most severe and deadly diseases, such as rabies, have documented cases of survival with proper medical intervention.
While some diseases have very low survival rates, such as Creutzfeldt-Jakob disease, amyotrophic lateral sclerosis (ALS), and acute fulminant hepatitis, there is always hope for recovery or extended life expectancy with advancements in medical research and treatment.
It is important to remember that every individual is different, and even within the same disease, survival rates can vary depending on factors such as age, overall health, and access to healthcare.
