Buruli ulcer
The annual number of suspected Buruli ulcer cases reported globally was around 5000 cases up until 2010 when it started to decrease until 2016, reaching its minimum with 1961 cases reported. Since then, the number of cases has started to rise again every year, up to 2713 cases in 2018. In 2020 1258 cases were reported compared with 2271 cases in 2019. The reduction in 2020 could be linked to the impact of Covid-19 on active detection activities.
