Relative annual trends of P. falciparum and P. vivax malaria in Jimma town, 2000-2009. The figure demonstrates that a high fluctuation of malaria cases at species level in the study area. With the exception of some years, a high predominance of P. falciparum over P. vivax was observed. Thus the remarkable increment in total malaria cases was mainly due to the increment of P. falciparum rather than P. vivax except that by the year 2009 P. vivax was found to be highly diagnosed relative to P. falciparum which indicates that currently there was a trend shift from P. falciparum to P. vivax malaria in the study area.
