  • "The Department of Health - Australia - Malaria Laboratory Case Definition (LCD)". Australian Department of Health. Archived from the original on 29 July 2020. Retrieved 21 December 2020. "Recrudescence" is the term for recurrence of infection with all malaria species including P. falciparum, P. malariae and P. knowlesi, which lack hypnozoites. This occurs when the infection (unless a new infection) has persisted in the blood at undetectable levels and then becomes detectable again. ... . If, following reactivation of a latent hypnozoite in the liver, a relapse occurred, then that individual would, potentially, be able to spread the infection to mosquitoes (provided that there were gametocytes in the blood). Malaria epidemiologists consider that each relapse has the potential to establish a new focus of transmission and, thus constitutes a new case. ... In the case of the persistence of drug-resistant parasites, there would be no clearance of parasitaemia even though it might be reduced to sub-patent levels for a time. This would be the same case but, in this instance, recurrence would be termed "recrudescence" not "relapse" (refer above). The period of 8 weeks used to exclude recrudescence as the cause of recurrences of chloroquine-resistant P. vivax is somewhat arbitrary, but it does extend beyond the period during which there would be sufficient drug present to suppress the resistant parasites below patency.
