A non-communicable disease (NCD) is a disease that is not transmissible directly from one person to another. NCDs include Parkinson's disease, autoimmune diseases, strokes, most heart diseases, most cancers, diabetes, chronic kidney disease, osteoarthritis, osteoporosis, Alzheimer's disease, cataracts, and others.
Many common diseases are spread through vectors, such as viruses, bacteria, parasites, and pathogens. However, non-infectious or non-communicable diseases are not able to be spread from one person to another. They may be caused by our genetics, or they may be caused by our lifestyle choices and environmental exposure.
Asthma is a chronic, inflammatory, non-infectious lung disease characterized by recurrent breathing problems. People with asthma have airways that narrow more easily than non-asthmatics and are usually allergic to inhaled allergens.
This article will focus on the most common and deadly types of infection: bacterial, viral, fungal, and prion.
Cardiovascular diseases account for most NCD deaths, or 17.9 million people annually, followed by cancers (9.0 million), respiratory diseases (3.9million), and diabetes (1.6 million). These 4 groups of diseases account for over 80% of all premature NCD deaths.
Noninfectious diseases are not contagious because they are not caused by pathogens. Instead, they are caused by such factors as lifestyle choices, environmental toxins, or mutations.
Collectively NCDs account for more than 73% of global deaths. As the world is making progress in the fight against many infectious diseases, and as populations age, we expect that NCDs will become increasingly dominant as the cause of death.
Examples of non-communicable diseases include diabetes, Alzheimer's, cancer, osteoporosis, chronic lung disease, stroke, and heart disease. Almost four-fifths of all deaths from non-communicable diseases occur in developing countries.
Infectious diseases are diseases caused by living organisms like viruses and bacteria. They can be passed from person to person through body secretions, insects or other means. Examples are SARS, influenza, the common cold, tuberculosis (TB), Hepatitis A and B.
Infectious diseases commonly spread through the direct transfer of bacteria, viruses or other germs from one person to another. This can happen when an individual with the bacterium or virus touches, kisses, or coughs or sneezes on someone who isn't infected.
Infectious diseases are caused by pathogenic microorganisms, such as bacteria, viruses, parasites or fungi; the diseases can be spread, directly or indirectly, from one person to another. Zoonotic diseases are infectious diseases of animals that can cause disease when transmitted to humans.
Like bacterial infections, many viral infections are also contagious. They can be transmitted from person to person in many of the same ways, including: coming into close contact with a person who has a viral infection. contact with the body fluids of a person with a viral infection.
A disease that is not contagious is called a noninfectious disease. These diseases are not caused by pathogens. Instead, they are likely to have causes such as lifestyle factors, environmental toxins, or gene mutations. Common types of noninfectious diseases include cancer, diabetes, and immune system diseases.
Reducing the major risk factors for noncommunicable diseases (NCDs) – tobacco use, physical inactivity, unhealthy diet and the harmful use of alcohol – is the focus of WHO's work to prevent deaths from NCDs.
An infectious agent is something that infiltrates another living thing, like you. When an infectious agent hitches a ride, you have officially become an infected host. There are four main classes of infectious agents: bacteria, viruses, fungi, and parasites.
obesity is associated with an elevated risk of several major non-communicable diseases, including type 2 diabetes, coronary heart disease, stroke, asthma, and several cancers. et al.
The four main types of noncommunicable diseases are cardiovascular diseases (like heart attacks and stroke), cancer, chronic respiratory diseases (such as chronic obstructed pulmonary disease and asthma) and diabetes.
Diseases that are not contagious are called non-infectious or non-communicable diseases because they can't be spread from one person to another. So there's no vector for them to move from one host to another, no virus, no bacteria, no pathogen.
A disease that is not contagious is called a noninfectious disease. These diseases are not caused by pathogens.

Common types of noninfectious diseases include cancer, diabetes, and immune system diseases.
Infectious diseases are caused by microscopic germs (such as bacteria or viruses) that get into the body and cause problems. Some — but not all — infectious diseases spread directly from one person to another. Infectious diseases that spread from person to person are said to be contagious.
Depression and physical noncommunicable diseases: The need for an integrated approach. The significant burden due to depression that is comorbid with chronic physical disease, coupled with limited resources, makes it a major public health challenge for low- and middle-income countries.
