|Classification and external resources|
In general, the term "infestation" refers to parasitic diseases caused by animals such as arthropods (i.e. mites, ticks, and lice) and worms, but excluding conditions caused by protozoa, fungi, bacteria, and viruses, which are called infections.
External and internalEdit
Infestations can be classified as either external or internal with regards to the parasites' location in relation to the host.
External or ectoparasitic infestation is a condition in which organisms live primarily on the surface of the host (though porocephaliasis can penetrate viscerally) and includes those involving mites, ticks, head lice and bed bugs.
