The second reference -- https://www.hrsa.gov/hansens-disease -- shows cases in the entire US bouncing from around 160 to 220 since _2011_ up through 2020: "Most (95%) of the human population is not susceptible to infection... Treatment with standard antibiotic drugs is very effective." The Florida dashboard which is the third reference shows 14 cases in that state total in 2021.
