Concept Unique Identifier (CUI): C0009450
NCI Thesaurus Code: C26726 (see NCI Thesaurus info)
Semantic Type: Disease or Syndrome
NCIt Definition: A disorder resulting from the presence and activity of a microbial, viral, fungal, or parasitic agent. It can be transmitted by direct or indirect contact.
RADLEX Definition: Invasion and multiplication of microorganisms in body tissues, which may be clinically inapparent or result in local cellular injury. A local infection may persist and spread by extension to become an acute, subacute, or chronic clinical infection or disease state. It may also become systemic when the microorganisms gain access to the lymphatic or vascular system. (From Dorland, 27th ed) [MeSH]
Infectious diseases kill more people worldwide than any other single cause. Infectious diseases are caused by germs. Germs are tiny living things that are found everywhere - in air, soil and water. You can get infected by touching, eating, drinking or breathing something that contains a germ. Germs can also spread through animal and insect bites, kissing and sexual contact. Vaccines, proper hand washing and medicines can help prevent infections.
There are four main kinds of germs:
NIH: National Institute of Allergy and Infectious Diseases
MSH Definition: An illness caused by an infectious agent or its toxins that occurs through the direct or indirect transmission of the infectious agent or its products from an infected individual or via an animal, vector or the inanimate environment to a susceptible animal or human host.
NICHD Definition: A disorder resulting from the presence and activity of a microbial, viral, fungal, or parasitic agent. It can be transmitted by direct or indirect contact.
CDISC Definition: A disorder resulting from the presence and activity of a microbial, viral, or parasitic agent. It can be transmitted by direct or indirect contact. (NCI)
NCI-GLOSS Definition: Invasion and multiplication of germs in the body. Infections can occur in any part of the body and can spread throughout the body. The germs may be bacteria, viruses, yeast, or fungi. They can cause a fever and other problems, depending on where the infection occurs. When the body's natural defense system is strong, it can often fight the germs and prevent infection. Some cancer treatments can weaken the natural defense system.
CSP Definition: broad class of diseases whose causative agents may be passed between individuals in many different ways.
CSP Definition: invasion and growth of microorganisms in body tissues, which may be clinically inapparent or result in local cellular injury; a local infection may persist and spread by extension to become an acute, subacute, or chronic clinical infection or disease state or it may become systemic when the microorganisms gain access to the lymphatic or vascular system; does not always lead to injury of the host even if the pathogen is potentially virulent.
