Table 2.
Prevalence of infection by P. vivax (Pv total), P. vivax gametocytes (Pv gam), P. falciparum (Pf total) and P. falciparum gametocytes (Pf gam) as determined by light microscopy and PCR. Microscopy data available only for cross-sectional survey (CS) 1, overall prevalence by PCR determined as 18S rDNA copies/μl by qPCR, gametocyte prevalence by PCR determined by RT-qPCR (pvs25 transcripts/μl)
