Of 97 Indians examined in the Toototobi River area, Amazonas State, Brazil, in 1976, 91.7% were infected with Onchocerca. This was much higher than in a previous survey in 1973 (63.8%). Whereas in the earlier survey only one skin snip had been taken (from the upper part of the body), in the 2nd survey 2 were taken, one from the upper body and one from the buttocks; the number of microfilariae found in the lower part of the body was greater than that in the upper part.
