is one of the deadly disease caused by four main species of protozoan: P.VivaxrnP.falciparum, P.ovale and P.malariae. The 5th species P. knowlesi also infect human beingrnoccasionally. Malaria is transmitted by female anopheles mosquito. The aim of this study was tornassess and analyze the trends of malaria prevalence from 2006 to 2015 G.C. at Atat primaryrnhospital and associated risk factor to malaria infection. For this study data were taken from thernhospital registration log book for a period of ten years from 2006 to 2015 G.C. Moreover, datarnfor risk factors were collected from randomly selected households to which structuredrnquestionnaires were provided.rnAmong the recorded malaria cases there is no clear trends idea as to which sex is more affected byrnmalaria. In 2006, 2007 and 2011 roughly, 4%, 3%, 5%, , males were, respectively infected byrnmalaria. Conversely in 2008, 2009, 2012, 2013, 2014, 2015 about 3%, 4%,2%, 4%, 1% and 4%rnfemales were, respectively infected with malaria. As to which species of Plasmodium dominantlyrninfect heman being in the study hospital in 2006, 2007, 2008, 2009, 2010, 2011, and 2013 over 50%rnof malaria was caused by P. vivax, while in 2012, 2014, 2015 the highest proportion was causedrnby P. falciparum. Among malaria cases in different age groups, there is no clear trend as it variesrnfrom year to year. The highest record of malaria was in October to December followed April-rnJune and the least was from January to March for all years. The prevalence of malaria withrnregard to sex, and age are statistically insignificant (P>0.05), The prevalence of malaria withrnseasonal variation is statistically significant P
