The high prevalence and intensity of ascariasis on these two atolls was contrasted with previously described STH studies in mainland East Kwaio villages, where hookworm predominates and ascariasis is almost absent. This led to a preliminary consideration that transmission of A. lumbricoides on densely populated coral atolls might be associated with defecation into the sea and transmission in seawater, although further work is required to investigate this hypothesis.

The decline in malaria cases in the AAH catchment area has been spectacular, particularly for Pf. This was supported by three sources of hospital surveillance data (laboratory, admissions and treatment records). The decline was associated with the use of artemisinin-based combined therapy and improved vertical social capital between the AAH and the local communities. Calculating village-specific API has highlighted which villages need to be targeted by the AAH malaria control team.
