Concepts

Airborne transmission

Disease transmission by airborne particles

Bloodstream infection

Medical condition

Agent that carries and transmits an infectious pathogen into another living organism

A profoundly debilitating, often deadly infectious disease, which proves highly contagious, yet limited to a specific area and period

Fecal–oral route

Disease transmission via pathogens from fecal particles

Foodborne illness

Illness resulting from food that is spoiled or contaminated by pathogenic bacteria, viruses, parasites, or toxins

Fungal infection

Fungal infection of animals, including humans

Macroparasitic disease in which a part of the body is infected with parasitic worms

Immunity (medicine)

Balanced state of having adequate biological defenses to fight unwanted biological invasion

Invasion of an organism's body tissues by disease-causing agents

Introduction to viruses

Non-technical introduction to viruses

Mosquito-borne disease

Disease caused by bacteria, viruses or parasites transmitted by mosquitoes

Opportunistic infection

Infection caused by pathogens that take advantage of an opportunity not normally available

Widespread, often global, epidemic of severe infectious disease

Parasitic disease

Medical condition

Biological entity that causes disease in its host

Pathogen transmission

Passing of a pathogen from one organism to another

Pathogenic bacteria

Disease-causing bacteria

Pathogenic type of misfolded protein

Respiratory tract infection

Infectious disease affecting nose, throat and lungs

Reverse zoonosis

Pathogens capable of transmitting from humans to other non-human animals

Sexually transmitted infection

Infection transmitted through human sexual behavior

Skin disease caused by bacteria, fungi, parasites or virus

Tick-borne disease

Medical condition

Urinary tract infection

Infection that affects part of the urinary tract

Human, animal or plant disease resulting from a viral infection

Infectious agent that replicates in cells

Ability of some viruses to lie dormant within a cell

Waterborne disease

Diseases caused by pathogenic microorganisms transmitted in water

Diseases of humans caused by a pathogen
