  1. Buruli Ulcers A neglected tropical disease By Geraldine Ambe Walden University 10/24/09

  2. Disease etiology • Environment • Agent host interaction • Cultural aspects • Behaviors • Population

  3. Background • Buruli ulcers known as bairnsdale ulcer, daintree ulcer, mossman ulcer, searl ulcer, necrotizing disease of soft tissue. • Cause mycobacterium ulcerans. • Rapid emergency of disease in most parts of Africa. • WHO tools for better Bu control and surveillance.

  4. Prevalence • Reported in over 30 countries. • Largest numbers in Zaire, Congo, Cameroon, Nigeria, Benin, Ghana, Togo, Liberia, Ivory coast, Australia, southeast Asia.

  5. BARRIERTODETERMINEEXACT PREVALENCE • Under reporting • Under diagnosing • Lack of access to health care • Multiple clinical presentation of disease • Limited knowledge of healthcare workers • Limited public knowledge about the disease

  6. Epidemiology • Occurs near water bodies, rivers, lakes, swams, ponds( activities farming) • Most afflicted children age 15years and under • 90% of lesions on limbs • 60% lower limbs.

  7. MORTALITY AND MORBIDITY • Disease has low mortality rate • High morbidity and socioeconomic burden • Prolong debility • Severely handicapping

  8. Numerical Data • Countries Population 2002 2003 • Benin 6,097,000 565 724 • Cameroon 15,481,00 132 230 • Cote d’ivoire 17,109,00 0 1235 • Ghana 20,212,00 853 739 • Togo 4,629,00 96 56 • Guinee 8,185,820 328 157

  9. Causes • M Ulcerans slow growing mycobacteria causative agent of BU • An environmental pathogen, isolated from biofilms and small aquatic animals of slow moving, or stagnant bodies of water. • Suggested transmission, mosquitoes bites.

  10. Signs and Symptoms • BU starts as a painless, mobile swelling in the skin. • Large area of induration • Diffuse swelling • No pain and fever • Incubation period few weeks to months.

  15. Treatment • WHO Recommendations • Rifampin / Streptomycin • Antimicrobials • Surgical intervention

  16. Social and Cultural Aspects • Sociocultural belief • Fear • Stigma • Loss of productivity • Cost of treatment

  17. Control and Surveillance • Reduce disability • Early detection • Training health care professionals • Case Management • Laboratory case confirmation • Advance health facilities • Monitor, evaluate control activities.

  18. Goals • Improve case finding. • Improve case management • Improve surveillance • Improve Channels of communication. • Increase Research studies on Buruli ulcers.

  19. Audience • Members of heavy burden communities • Medical health care professionals, (Doctors, nurses, laboratory workers, other health clinicians. • Village leaders • community field workers • University medical student and nursing school students.

  20. Organizations • Centers for disease control and prevention (CDC) • UNICEF • World Health Organization (WHO) • Doctors without Borders. • Buruli ulcer control programme Headquaters in Harare Zimbabwe.
