Summary
- 1. A survey of natural immunity to yellow fever among the primates of Brazil has been going on for the past 15 years, more than 5,800 sera have been examined in all.
- 2. Sixty-five per cent were obtained from monkeys and 35 per cent from marmosets.
- 3. Immune primates have been found almost everywhere except in the seven states of the northeast, no extensive surveys having yet been carried out in that region.
- 4. The wide extent of specific immunity among primates captured in nature confirms the fact that jungle yellow fever has prevailed throughout most of Brazil during the past decade and a half.
