Pathogen
A disease-causing biological agent, such as a bacterium, virus, or parasite
A disease-causing biological agent, such as a bacterium, virus, or parasite
An illness caused by a pathogen entering and reproducing in a host
An infectious disease that can pass from one host to another, directly or indirectly
The route by which a pathogen moves from a source or reservoir through an environment, medium, or vector into a susceptible host
The population or environment in which a pathogen normally lives or persists
A living organism, such as a mosquito or flea, that carries a pathogen from one host to another
An infectious disease transmitted from nonhuman animals to humans
Transmission through water contaminated with pathogens, often by fecal waste
Transmission by inhaling infectious droplets or smaller particles released by an infected person
Transmission through the bite or activity of a living organism carrying a pathogen between hosts
Transmission through contact with contaminated bodily fluids, tissues, or surfaces
Transmission through sexual contact with infected bodily fluids
Natural selection that makes pathogen variants suited to new hosts, vectors, environmental conditions, or control measures more common
The ability of pathogens to survive antimicrobial drugs, promoted when drug use selects for resistant variants
A bacterial disease commonly transmitted by infected flea bites or by contact with contaminated fluids or tissues
A bacterial infection that usually attacks the lungs and spreads when people inhale bacteria released by an infected person
A parasitic disease transmitted by infected female Anopheles mosquitoes and most prevalent in sub-Saharan Africa
A viral disease transmitted to humans by infected mosquitoes, with birds serving as the principal reservoir hosts
A viral respiratory illness and form of pneumonia spread by inhaling infectious respiratory particles or contacting infected fluids
A viral respiratory illness transmitted from animals, especially dromedary camels, to humans and sometimes between people
A viral disease spread mainly by infected Aedes mosquitoes but also through sexual contact and from a pregnant person to a fetus
A bacterial disease contracted by consuming water or food contaminated with Vibrio cholerae, commonly through fecal contamination
