Brief summary

Buruli ulcer is a destructive disease of the skin and soft tissue that is caused by the bacterium Mycobacterium ulcerans. There is currently a major outbreak of Buruli ulcer in Victoria, specifically in the Mornington and Bellarine Peninsulas. It is unclear how humans acquire the disease. Further information regarding how Buruli ulcer is transmitted may help to prevent the disease and its complications. This study is investigating whether people who live in or visit endemic areas carry the bacteria on their skin. This has implications for how Buruli ulcer is transmitted. Participants will self-collect swabs of their skin (of backs of elbows, wrists, calves and ankles), which will be tested for the presence of Mycobacterium ulcerans DNA by PCR.

Interventions

We will approach Buruli Ulcer(BU) patients and their friends and relatives living or visiting one endemic area where there is a major outbreak of Buruli ulcer currently (near Melbourne Australia). After explanation and instruction via leaflet participants will be asked to self-collect skin swabs. They will dip a swab in sterile saline and self-swab their skin after a day outside in the endemic area. They will be asked to swab the back of the elbows, the back of the wrists, ankles and calves on

We will approach Buruli Ulcer(BU) patients and their friends and relatives living or visiting one endemic area where there is a major outbreak of Buruli ulcer currently (near Melbourne Australia). After explanation and instruction via leaflet participants will be asked to self-collect skin swabs. They will dip a swab in sterile saline and self-swab their skin after a day outside in the endemic area. They will be asked to swab the back of the elbows, the back of the wrists, ankles and calves on both sides of the body. Participants will also be asked to fill in a questionnaire about their activities and clothing. They will then mail the swabs to our research laboratory, where the swabs will be tested by PCR for the presence of M. ulcerans DNA. Informed written consent will be obtained. We will also enrol scientists involved in environmental surveys in the outbreak area, and ask them also to swab their elbows, wrists, ankles, backs of calves before showering at the end of the day. These swabs will be tested as above.
