Strategic Options and Alternative Treatment Strategies for Accelerating Onchocerciasis Elimination in Africa
Elimination by 2025 requires that the criteria for stopping treatment are met latest in 2022 to allow for the confirmation of elimination three years later . To achieve elimination of onchocerciasis in at least 80% of onchocerciasis endemic African countries by 2025, the reduction in transmission has to be accelerated in areas for which currently available data suggest that the criteria for stopping CDTI will not be reached by 2022.
Acceleration of the reduction in transmission can be achieved either by improving the implementation of annual CDTI, notably increasing CDTI treatment coverage, or by using alternative treatment strategies (ATS) where CDTI cannot be implemented effectively (in particular in areas co-endemic for loiasis), or CDTI effectiveness is considered sub-optimal.
