The mode(s) of transmission of Buruli ulcer are still uncertain and are likely to differ between West Africa and Southeast Australia. However, hypotheses such as M. ulcerans contamination via aquatic niches [10], host-to-host transmission between humans and animal reservoirs (including possums) [8], and transmission via insect mechanical vectors (including mosquitoes) [9] have been proposed. These hypotheses are explored in this review. Created with BioRender.com.
