Modeling the risk of malaria for travelers to areas with stable malaria transmission
Abstract Background Malaria is an important threat to travelers visiting endemic regions. The risk of acquiring malaria is complex and a number of factors including transmission intensity, duration of exposure, season of the year and use of chemoprophylaxis have to be taken into account estimating r...
