This is a retrospective descriptive analysis of six years of routine surveillance and immunization data from a single rural border district in Ghana, documenting temporal patterns in measles notifications and vaccine coverage without testing causal hypotheses. The study reports substantial year-to-year variation in measles occurrence, inconsistent two-dose MCV coverage, and periods of high MCV1-MCV2 dropout, but acknowledges significant limitations in denominator validity, administrative coverage plausibility, and case classification completeness that complicate interpretation.
Retrospective descriptive study. Chereponi District, North East Region, Ghana, a predominantly rural border district with approximately 96,000 people (2024 projection) and more than 200 communities. Healthcare services delivered through district hospital, health centres, and CHPS compounds under Ghana's Integrated Disease Surveill…. n = 167. Chereponi District, North East Region, Ghana; borders the Republic of Togo..
167 suspected measles cases reported 2019–2024, of which 31 (18.6%) were laboratory-confirmed Children aged 0–4 years accounted for 66.9% of suspected cases with recorded age; 5–9-year-olds accounted for 23.4% MCV1 reached 95% only in 2020; MCV2 remained below 90% in four of six years

District health officials and programme managers can use this data to identify operational gaps in routine immunization delivery, dropout, and case detection specific to a rural border setting; the findings support targeting defaulter tracing, outreach, and denominator validation. However, the descriptive nature and acknowledged data quality limitations mean this should inform programme monitoring questions rather than policy decisions without external validation.

Objectives. To describe temporal patterns in measles occurrence and measles-containing vaccine (MCV) coverage in Chereponi District, Ghana, from 2019 to 2024.Methods. A retrospective descriptive study analysed routine SORMAS and DHIMS2 data from 2019 to 2024. Annual suspected and laboratory-confirmed measles incidence, MCV1 and MCV2 coverage, and MCV1-MCV2 dropout were summarized descriptively.Results. During 2019-2024, 167 suspected measles cases were reported through district surveillance, of which 31 (18.6%) were laboratory-confirmed. Children aged 0-4 years accounted for 66.9% of suspected cases with recorded age, while 5-9-year-olds accounted for 23.4%. Suspected notifications peaked in 2022, whereas laboratory-confirmed incidence was highest in 2023. MCV1 reached 95% only in 2020, while MCV2 remained below 90% in four of six years. MCV1-MCV2 dropout exceeded 10% in four years and declined to 8.6% in 2024.Conclusion. Chereponi experienced substantial year-to-year variation in measles occurrence amid inconsistent two-dose MCV coverage and periods of high dropout. Strengthening routine immunization, defaulter tracing, outreach, denominator validation, and case-based surveillance remains essential for measles elimination.
