Measles remains a highly contagious, vaccine-preventable disease with significant morbidity, particularly among under-immunized populations. Despite routine immunization and Supplementary Immunization Activities (SIAs), Ethiopia continues to experience recurrent outbreaks. The 7-1-7 framework provides benchmarks for timely outbreak detection, notification, and early response actions. This study aimed to describe measles outbreak epidemiology and evaluate response timeliness using 7-1-7 framework in Geze Gofa District of Southern Ethiopia. A mixed-methods field investigation was conducted from January to February 2025. Data were collected through active case finding, health facility record reviews, interviews with healthcare workers and caregivers, and observation of vaccination documentation. The 7–1–7 framework was applied to assess the timeliness of detection, notification, and response. Descriptive statistics were used to analyze case demographics and response timelines, while thematic analysis was employed to identify bottlenecks and enablers. A total of 39 measles cases were identified, predominantly children aged 1–14 years (82.1%). Overall district attack rate was 0.37 per 1000 population 95% CI: 0.27–0.51, highest among children 0–4 years (1.11 per 1000 population 95% CI: 0.65–1.78. The outbreak was notified within 1 day, meeting the 7–1–7 benchmarks. However, detection took place 11 days after the first case emergence and response activities were initiated in full at 11 days, both of which exceeded the target of 7 days. The delay in detection was mainly due to the absence of active surveillance in the community, and the response was further delayed by the need for laboratory confirmation, which took 10 days. Additional challenges included rugged terrain, limited vaccine supply, and insufficiently trained personnel. Despite these barriers, early notification were facilitated by trained health workers at outpatient service department and effective mobile communication systems. Notably, 13% of cases were unvaccinated, and an additional 12.8% had unknown vaccination status, despite reported MCV1 and MCV2 coverage rates of 96% and 94%, respectively in Geze Gofa District. The Geze Gofa measles outbreak response demonstrated strengths in notification but was hindered by delayed detection and response initiation due to systemic and logistical constraints. To enhance outbreak preparedness and align with the 7–1–7 framework, active surveillance should be strengthened, and national protocols should be revised to allow provisional vaccination based on clinical and epidemiological evidence. Decentralizing laboratory services and strengthening vaccine logistics are also critical to improving response timeliness and effectiveness.
