What is a "pathogen"?
A pathogen is a type of microorganism, such as a bacterium, virus, fungus, or parasite, that can cause diseases. These harmful organisms have the ability to invade and multiply within the body, leading to infection and illness. Pathogens can be spread through various ways, including direct contact with infected individuals, contaminated food or water, or insect bites. Understanding and controlling pathogens are critical in preventing the spread of infectious diseases, often through measures such as vaccination and hygiene practices.
Example
The pathogen responsible for malaria is transmitted to humans through the bite of an infected mosquito.
The researchers identified a new viral pathogen that was causing the outbreak of respiratory illness in the community.
Proper hand hygiene and sanitation practices are crucial in preventing the spread of pathogens in healthcare settings.
Vaccines are designed to protect against specific pathogens by stimulating the immune system to recognize and fight them.
The laboratory tests confirmed the presence of a bacterial pathogen responsible for the patient's severe food poisoning.
