INTRODUCTION: @entity311 transmission occurs most frequently in environments with humidity greater than 60% and ambient temperature of 25    C to 30    C. Risks increase with longer visits and depend on activity. Infection can follow a single mosquito bite. Incubation is usually 10 to 14 days but can be up to 18 months depending on the strain of parasite. METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of non-drug preventive interventions in non-pregnant adult travellers? What are the effects of drug prophylaxis in non-pregnant adult travellers? What are the effects of antimalaria vaccines in adult and @entity1 travellers? What are the effects of antimalaria interventions in @entity1 travellers, pregnant travellers, and in airline pilots? We searched: Medline, Embase, The Cochrane Library, and other important databases up to November 2009 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). RESULTS: We found 79 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. CONCLUSIONS: In this systematic review we present information relating to the effectiveness and safety of the following interventions: aerosol insecticides, @entity16944 , air conditioning and electric fans, @entity20497 - @entity24517 , biological control measures, @entity503 (alone or with @entity24517 ), @entity45419 ( @entity2471 ), dietary supplementation, @entity3403 , electronic mosquito repellents, full-length and light-coloured clothing, insecticide-treated clothing/nets, mefloquine, mosquito coils and vapourising mats, @entity12433 , @entity4765 - @entity3761 , @entity4765 - @entity9230 , smoke, topical (skin-applied) insect repellents, and vaccines.
