Fullscreen A disease is defined as a physical or mental disorder or malfunction with a characteristic set of signs or symptoms. Diseases may be caused by a single factor or be multifactorial. There are a number of different causes of disease in humans.
It is often inherited, but some mutations are random and de novo. Hereditary or inherited disease a type of genetic disease caused by mutation that is hereditary and can run in families Iatrogenic disease A disease condition caused by medical intervention.
Idiopathic disease disease whose cause is unknown. As medical science has advanced, many diseases whose causes were formerly complete mysteries have been somewhat explained for example, when it was realized that autoimmunity is the cause of some forms of diabetes mellitus type 1even if we do not yet understand every molecular detail involved or even extensively explained for example, when it was realized that gastric ulcers are often associated with Helicobacter pylori infection.
Incurable disease disease that cannot be cured Primary disease disease that came about as a root cause of illness, as opposed to secondary disease, which is a sequela of another disease Secondary disease disease that is a sequela or complication of some other disease or underlying cause root cause.
Bacterial infections can be either primary healthy but then bacteria arrived or secondary to a viral infection or burnwhich predisposed by creating an open wound or weakened immunity bacteria would not have gotten established otherwise.
Terminal disease disease with death as an inevitable result Illness Illness and sickness are both generally used as a synonym for disease. Symptoms of illness are often not directly the result of infection, but a collection of evolved responses — sickness behavior by the body—that helps clear infection and promote recovery.
Such aspects of illness can include lethargydepressionloss of appetitesleepinesshyperalgesiaand inability to concentrate. Medical disorders can be categorized into mental disordersphysical disordersgenetic disordersemotional and behavioral disordersand functional disorders.
The term disorder is often considered more value-neutral and less stigmatizing than the terms disease or illness, and therefore is a preferred terminology in some circumstances. However, the term disorder is also used in many other areas of medicine, primarily to identify physical disorders that are not caused by infectious organisms, such as metabolic disorders.
Medical condition A medical condition is a broad term that includes all diseases, lesionsdisorders, or nonpathologic condition that normally receives medical treatment, such as pregnancy or childbirth. While the term medical condition generally includes mental illnesses, in some contexts the term is used specifically to denote any illness, injury, or disease except for mental illnesses.
The Diagnostic and Statistical Manual of Mental Disorders DSMthe widely used psychiatric manual that defines all mental disordersuses the term general medical condition to refer to all diseases, illnesses, and injuries except for mental disorders.
Some health insurance policies also define a medical condition as any illness, injury, or disease except for psychiatric illnesses.
On the other hand, by emphasizing the medical nature of the condition, this term is sometimes rejected, such as by proponents of the autism rights movement.
This usage appears in statements that describe a patient as being in critical condition, for example. Among severely ill patients, the level of morbidity is often measured by ICU scoring systems.
Comorbidity is the simultaneous presence of two or more medical conditions, such as schizophrenia and substance abuse. In epidemiology and actuarial sciencethe term "morbidity rate" can refer to either the incidence rate, or the prevalence of a disease or medical condition.
This measure of sickness is contrasted with the mortality rate of a condition, which is the proportion of people dying during a given time interval. Morbidity rates are used in actuarial professions, such as health insurance, life insurance and long-term care insurance, to determine the correct premiums to charge to customers.
Morbidity rates help insurers predict the likelihood that an insured will contract or develop any number of specified diseases.

Zoonoses are infectious diseases that can be naturally transmitted between animals (usually vertebrates) and humans..
Major modern diseases such as Ebola virus disease and salmonellosis are zoonoses. HIV was a zoonotic disease transmitted to humans in the early part of the 20th century, though it has now mutated to a separate human-only disease.
Most strains of influenza that infect humans are. Causes The cause of Chagas disease is the parasite Trypanosoma cruzi, which is transmitted from an insect known as the triatomine bug.
