RESUMEN
A preliminary analysis of the distribution of snakes captured in Cameroon between 1999 and 2004 is presented in this study. This work helps to provide a better understanding of the distribution of the venomous snakes. The main focus of this study was to identify regions of high diversity of venomous species, a useful step towards developing a national strategy of snakebite care and antivenom distribution. We recorded 4,910 specimens of 150 species from 361 localities throughout Cameroon. Among the ten provinces in Cameroon, the southwest province recorded the highest number of venomous snakes. Diversity was less in the far-north province, but the high abundance of Echis ocellatus seems to be responsible for many snake bites in the region. Of all venomous snakes, the forest cobra Naja melanoleuca was the most abundant in the forest region. The humid savannah region was dominated by Causus maculatus while the Sahelian part by Echis ocellatus. Given the abundance and high snake bite cases of the latter in the region, snakebite care from a national point of view should begin from the far-north towards the forest region of the south-west Cameroon.

Two snake antivenoms are distributed in Cameroon, though their availability in district hospitals varies. These snake antivenoms are FAV-Afrique (Aventis Pasteur) available at Centre Pasteur Cameroun and Polyvalent serum (Serum Institute of India = SII) distributed by a wholesaler (CENAME). The price remains a very important factor. We have noted that some district hospitals do not stock antivenom at all, while others stock very few and sometimes only one vial whereas a good management of snakebite may require up to 14 vials for some envenomations. However, data collected by the CAMHERP project that permit to identify high-risk areas of envenomation might be used as a database for the distribution of snake antivenom in Cameroon.
