Study Notes
- Endemic diseases are repeatedly present in a population or area, such as the common cold.
- Sporadic diseases break out only occasionally, like typhoid fever in the U.S.
- Epidemic diseases occur with greater frequency than usual in a population, such as influenza.
- Pandemic diseases are worldwide epidemics, examples include AIDS and the 1918 influenza.
Reservoirs
- Reservoirs are sites where pathogens are maintained, acting as a source of infection.
- Animal reservoirs: Pathogens primarily infect animals, but can also affect humans, known as zoonoses.
- Human carriers: Individuals who are symptom-free but can still transmit pathogens to others.
- Nonliving reservoirs: Include soil, water, food, and fomites, all capable of harboring and spreading pathogens.
