Figure 1. Temporal distribution of P. vivax malaria episodes and serological evaluation of ELISA-detected IgG antibodies targeting PvDBP, Amazonas, Brazil (Nov 2008-Nov 2009).

Figure 1

(A) Episodes of malaria, as detected by conventional microscopy, varied according to rainfall and season; (B) DBPII-IV antibodies fluctuate with season while anti-DBPII remains stable. ELISA-detected antibody responses were evaluated November 2008, June 2009, and November 2009. Results are expressed as frequency (%) of responders, with Reactivity Index (RI)>1.0 considered positive; different superscripts (a–c) indicate significant differences (P<0.05 by Z-test.)
