Participants >18years interviewed and caregivers questioned for legality. Epi-info and SPSS were used for data entry and analysis respectively. Predictors were identified using chi-square at significant level P<0.05 with 95%CI, then analysed using logistic regression to identify associated factors. During the time 153 suspected cases, 9 suspected deaths were reported; among these 33(22%) cases and 3 deaths were verified. Among 33 cases 15(45.5%) were in July 2019, in comparison of 4years data, there is surge cases in July-August 2019, 26(79%) of cases were from Dire, AR=15/100,000, CFR=9.1%.
