Case definition for the classification of malaria

Malaria case	Confirmed malaria case (or infection) in which the parasite has been detected in a diagnostic test, i.e., microscopy, a rapid test, or a molecular diagnostic test
Malaria case, introduced	A case contracted locally, with strong epidemiological evidence linking it directly to a known imported case (first-generation local transmission)
Malaria case, imported	Malaria case or infection in which the infection was acquired outside the area in which it is diagnosed
Malaria case, indigenous	A case contracted locally with no evidence of importation and no direct link to transmission from an imported case
Malaria elimination	Interruption of local transmission (reduction to zero incidence of indigenous case) of a specified (human) malaria parasite in a defined geographical area as a result of deliberate activities. Continued measures to prevent re-establishment of transmission are required
