Recrudescence and relapse in Malaria

Recrudescence is a re-attack of malaria because of the surviving malaria parasites in red blood cells. Characteristic of P.malariae infections. This may be short term or delayed.

Relapse is a re-attack of malaria because of infection by the malarial parasites which were surviving in the liver (i.e. hypnozoites). This is usually a delayed feature.
