[Occurrence of onchocerciasis in subjects coming from non-endemic areas and migrating to a hyperendemic area].
The incidence of Onchocerca volvulus infection was measured from 1992-93 to 1995 in six villages of initially uninfected migrants who settled in 1991 in the Vina Valley (Cameroon), an area of ongoing transmission of onchocerciasis. The mean annual incidence (MAI) exceeded 20% in the three communities located in the first line, and fewer than 15 km from the hyperendemic areas of the Central African Republic. The MAI was lower than 16% in the second line communities. As these populations are particularly at risk of developing ocular complications from onchocerciasis, it is recommended that repeated ivermectin distributions be organized in the migrant villages of the Vina Valley.
