Infectious dose (ID) is the amount of pathogen (measured in number of microorganisms) required to cause an infection in the host.[1]

Usually it varies according to the pathogenic agent and the consumer's age and overall health.

Infectious doses for some known microorganisms[edit]

The likelihood of infection in all cases is also linked to the immune status of the individual (immunocompromised individuals may become infected more readily).[3]
