There is no “classic” definition of a measles out- break in Montenegro as country is in the elimi- nation phase. Defining and outbreak is based on several parameters with the main one being num- ber of endogenous cases, burden of the healthcare services and other

RVC comments, based on 2018 reporting

The RVC concluded that endemic transmission of both measles and rubella remained interrupted in Montenegro in 2018 and confirmed that measles- and rubella-elimination have been sustained. The RVC is concerned about the continuing low vaccination coverage, which has resulted in a dangerous accumulation of susceptible children and created a high risk for re-establishing transmission. The RVC encourages implementation of WHO strategies and recommendations to increase vaccination coverage and close existing immunity gaps. The RVC requests that the NVC work with its secretariat to ensure inclusion of genotyping data in future ASUs.
