Disease definition in medical
Disease definition – What is a disease? The disease is a structural or functional disorder in humans, animals, or plants. It causes cell and tissue abnormalities and localized symptoms.
The disease is a sickness with distinct indications or symptoms. Disease deteriorates cell, organ, and tissue function. Physical injury can’t cause the condition. Some diseases are infectious, whereas others aren’t. Examples of diseases include cancer, cholera, heart conditions, hepatitis, asthma, and others.
Diseases are classified into two types.
- Infectious Diseases
- Non-infectious Diseases
Infectious disease definition
Infectious diseases are caused by microorganisms such as parasites, viruses, fungi, or bacteria that can spread from person to person.
The transmission of infectious diseases can be stopped in one of two ways:
- By rendering the host resistant by selective breeding or creating a powerful artificial immunity; or
- By preventing interaction between the susceptible host and the source of the illness
For each disease, many types of preventative strategies have different effects.
Microorganisms are the source of infectious diseases, which can transfer from one person to another. Pathogens are microscopic creatures, including bacteria, viruses, fungus, worms, rickettsia, and protozoans that typically cause infectious diseases. It spreads when an infected person shares bodily fluids with another individual. The pathogens may then leave the original host and infect the new individual. For example, that can happen when sneezing, coughing, etc. Cholera, chickenpox, malaria, COVID-19, and other diseases are a few examples of this illness.
These diseases are brought on by viruses and other elements, including an unhealthy lifestyle, advanced age, gender, inadequate diet, etc. Examples include diabetes, high blood pressure, and cancer. These cannot be passed from one person to another and are not contagious. Instead, these bind the person who contracts them inside. Examples include heart diseases, Alzheimer’s, cataracts, and other eye conditions.
What are chronic diseases examples?
Chronic disease is a long-term condition that can be managed but not cured and lasts several months to several years. Examples of common chronic diseases include diabetes, cancer, hepatitis, and HIV/AIDS. Chronic diseases are the leading cause of death in industrialized and developing nations, with the number of deaths from chronic diseases in the USA rising by 1.7 million annually. It covers many forms of cancer, heart disease, diabetes, AIDS, and epilepsy, among other things.
