Resumo: A serological survey in the pygmy population of Djoum (Sud Cameroon) by means of a hemagglutination inhibition test against eleven antigens was carried out on 1,186 serum samples collected in 1972. Positive sera for yellow fever were studied by use of the seroneutralisation test. There is evidence of contact of this population with all the arboviruses described in this study but with some variations: the most active arboviruses are Chikungunya and O'Nyong Nyong in group A, Zika and Yellow fever in group B. Arbovirus activity in this population is lower than in the nonpygmy population of Cameroon forest areas. The presence of isolated yellow fever antibodies among unvaccinated children confirms the presence of sylvan virus. A large proportion of the population being non immune, there is a risk of an epidemic in this area.
