Onchocerciasis in savannah zones has a generally more severe impact on humans than on the population in the forest, although there the vector flies transmit more infectious larvae than the flies in the savannah. Recent comparative studies showed that either a multiplicity of factors contribute to the observed different disease levels or that many parasite strains exist showing contradictory transmission rates.
