Morbidity refers to a diseased state, disability, or poor health due to any cause. The term may be used to refer to the existence of any form of disease, or to the degree that the health condition affects the patient. In epidemiology, the term morbidity rate can refer to either the incidence rate, or the prevalence of a disease or medical condition.

How would you describe the morbidity of a disease?
Morbidity is when you have a specific illness or condition. Some examples of common morbidities are heart disease, diabetes, and obesity. You can have more than one morbidity at a time. When this happens, it's called comorbidity. Mortality is the number of deaths due to a specific illness or condition.

How do you measure morbidity?
The calculation for this rate is to divide the number of deaths in a given time for a given population by the total population. To keep these values concise and for ease of comparison to other health events, this number can be multiplied by 1000 to reflect the “per 1000” rate of the target population.

What is morbidity frequency?
Measures of morbidity frequency characterize the number of persons in a population who become ill (incidence) or are ill at a given time (prevalence). Commonly used measures are listed in Table 3.3.
How do epidemiologists calculate incidence rates?
However, epidemiologists far more commonly calculate incidence rates based on a numerator of cases observed or reported, and a denominator based on the mid-year population. This type of incident rate turns out to be comparable to a person-time rate.
How is the incidence rate calculated?
A person-time rate is generally calculated from a long-term cohort follow-up study, wherein enrollees are followed over time and the occurrence of new cases of disease is documented. Typically, each person is observed from an established starting time until one of four “end points” is reached: onset of disease, death, migration out of the study (“lost to follow-up”), or the end of the study. Similar to the incidence proportion, the numerator of the incidence rate is the number of new cases identified during the period of observation. However, the denominator differs. The denominator is the sum of the time each person was observed, totaled for all persons. This denominator represents the total time the population was at risk of and being watched for disease. Thus, the incidence rate is the ratio of the number of cases to the total time the population is at risk of disease.
What is incidence proportion?
Incidence proportion is a measure of the risk of disease or the probability of developing the disease during the specified period. As a measure of incidence, it includes only new cases of disease in the numerator. The denominator is the number of persons in the population at the start of the observation period.
How does incidence rate work?
An incidence rate describes how quickly disease occurs in a population. It is based on person-time, so it has some advantages over an incidence proportion. Because person-time is calculated for each subject, it can accommodate persons coming into and leaving the study. As noted in the previous example, the denominator accounts for study participants who are lost to follow-up or who die during the study period. In addition, it allows enrollees to enter the study at different times. In the NHANES follow-up study, some participants were enrolled in 1971, others in 1972, 1973, 1974, and 1975.

What do epidemiologists do?
Epidemiologists work in conjunction with other health professionals to study patterns, mediums of transmission, or determinants of a specific health event within a particular population. They also work proactively to learn about diseases not previously studied, such as Legionnaire disease and severe acute respiratory syndrome (SARS). For example, the World Health Organization (WHO) met in Geneva, Switzerland, in 2003 to discuss the epidemiology of SARS and learn about the disease’s risk factors, mediums of transmission, and reservoirs. These proactive studies better equip health professionals with the knowledge necessary for a robust response if a health-related event occurs, and in these cases, a disease outbreak. Other notable instances in which epidemiologists have played a role include historical, biological warfare, eradicating smallpox, relief efforts to victims of hurricanes and terrorist attacks, and, most recently, Ebola and Zika virus outbreaks. When responding to these health events, epidemiologists utilize previously collected, analyzed, and verified data to create, advise, and implement informed and targeted solutions to monitor and prevent the occurrence, worsening, or recurrence of population-level health-related events. Epidemiologists play an integral part in the maintenance of the overall health and wellness of many specific populations.
Why is education important for epidemiologists?
Through educational activism, epidemiologists can present their research and equip their audiences with the necessary background information to effectively understand and apply the epidemiology of a health event.
How does epidemiology help society?
Information intended to help make informed decisions, prepare for future adverse health events, or advance the general population's knowledge can be otherwise used for propaganda or scare tactics, especially in today's heavily connected society. The knowledge of laypeople can be taken advantage of by using excerpts from research papers taken out of context. For example, during the Ebola outbreak, early communication characterized the ensuing effort as lacking preparation, while later communication was mired in government mistrust. [3] During the outbreak, one of the avenues of communication that the Centers for Disease Control and Prevention used was Twitter. [4] While the original intention was to increase transparency and rapidly provide the public with information about the outbreak, it instead increased the likelihood of acting on data that had not been fully verified. This situation is especially true during disease outbreaks when information regarding its determinants may not be immediately peer-reviewed. [5] Information of varying reliability and quality then leads to the potential of spreading unnecessary terror or panic that may or may not be remediable by expert opinions.

Why is morbidity and mortality important?
Answer: Morbidity and mortality rates are an important concept as they allow measurement and comparison of health data. By exploring patterns and variations in the health outcomes, we can begin to hypothesize about possible determinants of population health, and this is the essence of descriptive epidemiology. Descriptive epidemiology relates to the study of variations in population health by time, person and place. Proper collection of morbidity and mortality statistics is essential; department of statistics and MoH are key collectors in Malaysia. Mortality data is usually more available than morbidity data but depends on death certification aspects, diagnostics criteria and other factors.

Summary
- Co-morbidity means that a person has more than one illness. Co-morbid conditions don't always have the same cause, but they may occur together and worsen each other.2 For example, obesity, depression, and diabetesare often co-morbid.
