infectious disease
Transmissible medical condition
An infectious disease is an illness caused by pathogens—bacteria, viruses, fungi, or parasites—that can spread from one organism to another.
Transmission occurs through various routes: direct contact, airborne particles, contaminated food or water, or vectors like mosquitoes.
Measles is a highly infectious disease that spreads through coughing and sneezing.
The term distinguishes conditions that can be "caught" from those arising from genetics, lifestyle, or environmental factors.
