Malaria real-time PCR: correlation with clinical presentation

Among 112 patients infected only by Plasmodium falciparum, WHO criteria of severity were compared with parasite load assessed by microscopy and quantitative PCR. Clinical severity was significantly correlated with higher parasite load as determined by microscopy (p < 0.001) and by PCR (p < 0.001). Hence, quantitative PCR might be useful to predict outcome.
