Answer

Over the past decades, the GeoSentinel Network of Travel Medicine providers has demonstrated that dengue has become more frequently diagnosed than malaria in travelers returning from tropical areas other than Africa. Such sentinel travel surveillance can augment global and national public health surveillance. More recent studies have not supported an earlier suggestion that climate change is also directly responsible for increased transmission. [11, 9, 12]
