Altogether, 3 serum samples we received from 5 districts and 29 suspected cases from local health centres. Samples were tested for the measles and rubella IgM antibody. This study measures the determinants of outbreaks using case-control study follows by total population one control design for each sample.

The type of epidemiologic curve is propagated epidemic curve (person to person disease) with 11 days means of incubation periode. This outbreaks is associated to person to person close contact (OR 3,4:95%CI 1.009-10.318, p≤0.05 and history of rubella vaccination OR 0.482, 95%CI:0.165-1.409, p≤0.05 with all laboratorium samples positively detected for IgM of rubella viruses. Conclusions: Eradication of rubella is considered to be feasible and beneficial that we need to work toward elimination with a focus on strengthening ongoing immunization.
