Social immunisation

Preventing future infection

Social contact with infectious colony members causes pathogen transmission to previously healthy colony members. Often, this cross-contamination only leads to low-level infection of the colony members, which does not cause disease but induces a protective immunisation.

Read more on how social contact to infectious nestmates can induce immune protection against future infection and how altered disease susceptibility shapes the sanitary care of the ants.
