Strengthening Applied Epidemiology in West Africa: Progress, Gaps, and Advancing a Regional Strategy to Improve Health Security.

The ability to prevent, promptly detect, and appropriately respond to a public health threat is essential for health security. Field epidemiology training has helped increase the quality and quantity of the public health workforce to strengthen disease surveillance, outbreak preparedness and response, and general public health capacity. We conducted a desk review on the status of the Field Epidemiology and Laboratory Training Program model in 16 countries in West Africa. We also developed a questionnaire and shared it with West African Health Organization (WAHO) member states to document their experiences and the status of training in their countries. WAHO organized a regional 3-day consultative meeting with major stakeholders in the region to examine progress, gaps, and challenges, and outline a roadmap to strengthen the Field Epidemiology and Laboratory Training Program. Stakeholders shared their experiences, engaged in discussions to identify strengths and gaps, and made plans on a way forward. Member states are at different levels of implementing field epidemiology and laboratory training programs in their countries, and, therefore, major gaps remain in the number and distribution of trained epidemiologists throughout West Africa. Member states implement different variants of the program and in some instances the same cadre of health workers are trained in different but comparable programs with different funding streams. Two member states had not begun implementing the training program. Developing regional centers of excellence was recommended in the long term while collaboration among member states to train the required number of epidemiologists to fill the acute needs could be helpful in the short and medium term. Curriculum harmonization and expansion, deployment and use of trained epidemiologists, accreditation of training institutions, and generation of indigenous funding streams are recommended to improve the Field Epidemiology and Laboratory Training Program in West Africa.

Outcome of Streptomycin-Rifampicin treatment of Buruli Ulcer in two Ghanaian districts.

INTRODUCTION: Buruli ulcer (BU) is an infectious skin disease, caused by Mycobacterium ulcerans, endemic in more than 30 countries worldwide especially Africa. Brong-Ahafo Region implemented WHO recommended daily treatment with streptomycin and rifampicin for eight weeks (SR8). Yet limited assessment of therapy exists. This study seeks to determine the outcome of SR8 therapy on BU in two endemic districts in Brong-Ahafo. METHODS: Longitudinal study was done with laboratory confirmed Buruli ulcer patients selected consecutively and put on SR8. Patient follow-up involved daily administration of SR8 and Bi-Weekly monitoring of treatment in the form of measurement of wound size and taking photographs. RESULTS: The mean age of participants was 34.6 ± 16.6 years with minimum and maximum ages of 10 to 65 respectively. Those in the 10-19year age group 13 (26%) were most affected. Majority, 26 (52%) had no formal education and 27 (54.0%) were peasant farmers. Thirty-eight (76.0%) had previously used traditional treatment. Forty completed treatment and of these, 28 (70.0%) healed completely and 12 (30. 0%) improved by 80%-90%. Duration of lesion before seeking healthcare (P =0.04), use of traditional treatment P < 0.001, clinical form of lesion P = 0.04, lesion category (p = 0.01), significantly affected healing. Mean time to healing, was 7.7 weeks (95% CI, 7.3 - 7.9). CONCLUSION: Though SR8 is effective in curing BU, late reporting, use of herbs and access to health care impeded wound healing. This calls for provision of accessible health care and education to improve early reporting.
