An observational study has shown that hospital admissions for skin infections and rates of acute rheumatic fever decreased in the Bay of Plenty after health initiatives for rheumatic fever commenced in 2011. However, ethnic and socioeconomic disparities persisted. Over the period 2017-2019, admission rates for skin infection among Māori decreased by 40% for preschoolers, 14% for school-age children and 24% for young adults, compared with the period 2007-2010. Māori experienced 90% of all acute rheumatic fever cases, and 80% of cases among school-age children. Rates of acute rheumatic fever over the period 2011-2019 decreased by 29% for under 30-year-olds and by 36% for school-age Māori compared with the period 2000-2010.
