Correlation between annual activity patterns of venomous snakes and rural people in the Niger Delta, southern Nigeria

Abstract

BackgroundVenomous snakes are among the most serious health hazards for rural people in tropical regions of the world. Herein we compare the monthly activity patterns of eight venomous snake species (Elapidae and Viperidae) with those of rural people in the Niger Delta area of southern Nigeria, in order to identify the periods of highest potential risk for persons, and the human group actually at greater risk of snakebite.ResultsWe documented that above-ground activity of all venomous snakes peaked in the wet season, and that high snake activity and high human activity were most highly correlated between April and August. In addition, we documented that women and teenagers were at relatively higher risk of encountering a venomous snake than adult males, despite they are less often in the field than men.ConclusionsOur results suggest that future programs devoted to mitigate the social and health effects of snakebites in the Niger Delta region should involve especially women and teenagers, with ad-hoc education projects if appropriate. We urge that international organizations working on social and health problems in the developing world, such as IRD, DFID, UNDP, should provide advice through specific programs targeted at especially these categories which have been highlighted in comparatively potential higher threat from snakebites than adult men.

Acute kidney injury after snakebite accident treated in a Brazilian tertiary care centre

“…The predominant area of origin in both AKI (90.5%) and non‐AKI (85.3%) groups was the rural area, with no statistical difference between the groups, corroborated by the fact that the accident is associated with people's activities in the countryside. Akani et al ., in their study, highlighted a strong correlation between human activity type (rural or urban) and the occurrence of snakebite accidents.…”

African Society of Toxinology: a new opportunity for integrating the control of envenomations in Africa

“…Biological and ecological studies conducted in different settings in sub-Saharan Africa confirm the close relationship between ophidian behavior and bite risk (22), opening new perspectives for the epidemiology and prevention of envenomation accidents.…”

Aspects of community ecology of reptiles in the swamp forests of the Upper Orashi Forest Reserve (Niger Delta, Nigeria)

“…These data (i) fully support previous studies revealing that the above‐ground activity of most reptiles peaks during the wet months in the African rainforests (e.g. Luiselli, ; Akani et al ., ; Akani, Petrozzi & Luiselli, ) and (ii) also show that the detectability of the single species may vary remarkably between seasons (Luiselli, ). Thus, when organizing effective sampling periods for surveying reptiles in the Afrotropical swamp forests, we urge to plan the field researches during the wet months to reduce the probability of missing the rarer species.…”
