[Scorpion poisonous stings in the population of Khouribga (Morocco)]

Poisonous stings caused by scorpion constitute a public health problem in Morocco because of their frequency severity and socio-economic consequences that they generate. The province of Khouribga surveyed for this study is situated in a zone of high incidence and high lethality caused by scorpion stings in Morocco. In order to analyze the epidemiological profile and the poisoning risk factors, we are presenting the results of a past study conducted from April to December 2001. It consisted in making an exhaustive follow up from admission to release of all patients stung by scorpion. These patients consulted a sanitary structure (dispensary health centre or hospital) in the province of Khouribga, Morocco. Within a total of 1212 cases of stings, 63% of them occurred at night (between 06 pm and 06 am) particularly during July and August. Youngsters under fifteen represented 36% of these cases. 3.4% of the people who got stung presented typical poisoning and envenomation. The delay expected from sting to transfer to a medical structure was 1.85 +/- 0.11 hours for the patients who recovered against 2.67 +/- 0.11 for those who did not recover. To be noticed as well that 1.3% of the subjects who got stung die. Variance analysis indicates that the type of sanitary structures receiving patients, admission classes, and age of patients influence significantly the recovery rate of people who are stung.
