Difference Between Morbidity and Mortality


Main Difference

Morbidity and Mortality are two terms which on reading seem similar to one another but actually are very different from each other. Unlike most words which look alike but are different, these two terms are not the opposite of each other and are unlinked. Morbidity is a medical term which in short refers to being too healthy for one’s liking. Mortality is a philosophical term which means forever. Expanding on the initial definitions of both these words, morbidity is a medical condition in which a person in mere words, becomes unhealthy. This is done by gaining a lot of weight by overeating or other factors. Mortality, on the other hand, is a large number of people who have died in a particular area. This explanation tells that both these terms are maybe related only in one way, which is the use of these words while talking about something grave. Other than that, there is no similarity between them. There are a few differences between them such as morbidity is not peculiar to a particular region or a class of people, it deals with individuals who are suffering from a disease. Mortality is unique to an area, it is the number of a pupil who have lost their lives in society. Most of the data related to the obesity are obtained from the World Health Organizations while most of the data related to deaths will be found with the national organizations for demography. A minor variation in their definitions can lead us to think that morbidity is the condition in which a living person can become mortal while a human person cannot be in an existing situation. Mortality is a term which is not commonly used among people in daily lives, but morbid is a word which is frequently used to express the state of someone who is in front of you.
