Extract

1. Disappearance of Simulium neavei after DDT-treatment of rivers in Kodera, Kenya, is still manifest after seven years, and the species seems to have been eradicated from the district.

2. Skin microfilaria rates have dropped from something under 7 per cent. to nil in the under 4 years age group; from 37 to 5 per cent. or less in the 4–8 years; and from 70 per cent. to 50 per cent. in adults.

3. The length of life of the adult worm can be at least seven years.
