We defined a suspected case as acute onset of blurred vision with abdominal pain, general body weakness, headache, or profuse sweating in a resident of Arua City or Madi-Okollo districts from 16–26 August 2022. We conducted a retrospective cohort study to identify risk factors for death among cases. Together with Uganda Police Force and the Uganda National Bureau of Standards, we collected samples of Gin X from Manufacturer A for toxicologic analysis at the Government Analytical Laboratory in Kampala and reviewed production permits on-site. Autopsies were carried out on all deceased case-patients who were taken to Arua Regional Referral Hospital.
