Pediculus humanus capitis on children in Mahé, Seychelles.

The incidence of Pediculus humanus capitis infestation in pre-school and schoolchildren in Mahé, Seychelles, was investigated. High infestation rates were discovered, particularly in urban schoolchildren at district schools. Infestation in pre-schoolchildren increased with age. Girls were more infested than boys. Control of infestation will not be possible using only the child health service and the school health service. A combined approach is necessary based on the family unit.

Birth weight of infants in The Seychelles.

In 1977, a retrospective survey was made of all singleton live births in one year at Victoria Hospital, Seychelles. The mean weight of male infants was 3105 (S.D. 526 g) and of female infants was 3019 (S.D. 498 g). Birth weight of females increased with maternal age and parity whilst males showed a peak birth weight at maternal age 21 to 30 years and at parity one to two.

An outbreak of type 2 dengue fever in the Seychelles, probably transmitted by Aedes albopictus (Skuse).

Between December 1976 and September 1977 the Seychelles group of islands in the Indian Ocean was struck by an extensive epidemic of dengue fever. The peak of the epidemic was in the last week of February. Type 2 dengue virus was isolated from patients and mosquitos. Aedes albopictus was the sole vector. The clinical picture was that of classical dengue. Haemorrhagic fever and the shock syndrome were not observed.Absenteeism from schools and offices, anamnestic questioning, and prevalence of antibodies in sera collected after the epidemic was over, indicated that approximately 75% of the population had been infected. Serological evidence was obtained of an epidemic of dengue in the islands more than 40 years earlier. This was confirmed by archival records.
