Figure 2From: Epidemiology of malaria in a village in the Rufiji River Delta, Tanzania: declining transmission over 25 years revealed by different parasitological metricsParasite prevalence in Nyamisati 1985–2010 including all ages, by microscopy and two PCR methods ( msp2 genotyping PCR and real-time species-specific PCR). The parasite prevalence by msp2- PCR for 1986 and 1993 as well as microscopy for 2010 were estimated from slide and msp2- PCR data, respectively, using the prevalence estimation tool developed by Okell et al. [26] (as indicated by *).Back to article page
