Fig. 2From: High proportions of asymptomatic and submicroscopic Plasmodium vivax infections in a peri-urban area of low transmission in the Brazilian AmazonRelation between P. vivax parasitaemia and gametocyte carriage and gametocyte density. A generalized additive model was used to describe gametocyte positivity (a). Plasmodium vivax parasitaemia was determined by qPCR (18S rDNA copies/μl) and gametocyte density by RT-qPCR (pvs25 transcripts/μl) (b)Back to article page
