Efficacy of DETT (20%) and EDH (15%) a Association against mosquito bites.Results of a survey in the field in Senegal

The authors report the results of a survey on the efficacy against mosquito bites of a repellent Mousticologne((R)) Special Zones Infestees (DEET 20%, EHD 15%). Two forms of the product, spray and gel, were tested in Senegal. Repellent efficacy was evaluated by exposing volunteers, both repellent-tr eated and untreated, to mosquito bites. The number of mosquito bites per pe rson and per night was 0.63 in the spray treated group (group 1), 6.03 in t he gel treated group (group 2) and 94.17 in the untreated group (group 3), The analysis of these results showed a significant difference between treat ed and untreated persons. Untreated persons were not protected against mosq uito bites, persons treated with the spray were protected for 12 hours and those treated with the gel had over 8 hours' protection. We concluded that a single application of the repellent Mousticologne((R)) in the field is ca pable of ensuring all-night protection against mosquito bites.
