<p>We enrolled 146 cases from 406 measles cases and 146 neighborhood controls. A case was a child aged 15 years and below who resided in Mutasa district and tested positive for measles from the 10th of April 2022 or was epidemiologically linked to a confirmed case. Interviewer-administered questionnaires were used to collect data on exposures. We reviewed child health cards for vaccination status, vaccination outreach schedules and the cold chain system. District preparedness and response was assessed using a checklist. Data were analysed for frequencies and odds ratios. Multivariable logistic regression analysis was performed to identify independent risk factors for contracting measles.</p>
