What is primary host and secondary host?

A primary host or definitive host is a host in which the parasite reaches maturity and, in most cases, reproduces sexually. A secondary host or intermediate host is a host that harbors the parasite only for a short transition period during one or more of its developmental stages.

What is a primary host in science?

the host in which a parasite becomes sexually mature and usually spends most of its life cycle.

What is definitive host and intermediate host?

The definitive host is the one which harbors the adult parasite and where the parasite reproduces sexually. The intermediate host is the host which harbors the larval stage or the asexual forms of the parasite.

What is incidental host?

A host that becomes infected, but is not required for the maintenance of the population of a pathogen, can usefully be called an incidental host. (Accidental host is frequently used, but this is arguably a teleological term and therefore undesirable.)
