Rationale
The correct answer is B: Malaria. Travelers can bring malaria back to the United States from regions where it is endemic, such as sub-Saharan Africa and South Asia. This is due to the transmission of malaria through infected mosquitoes. Malaria is the most common vectorborne disease introduced by travelers to the US.
A: Dengue is primarily transmitted through infected mosquitoes in tropical and subtropical regions, but it is less common among travelers returning to the US compared to malaria.
C: Onchocerciasis is transmitted by black flies in Africa and Central and South America, but it is not commonly introduced to the US by travelers.
D: Yellow fever is transmitted by infected mosquitoes in Africa and South America, but it is less common among travelers bringing it back to the US compared to malaria.
Summary: Malaria is the most common vectorborne disease introduced to the US by travelers due to its high prevalence in endemic regions and transmission through infected mosquitoes.
