Dengue fever is a viral infection transmitted by the Aedes mosquito, whereas malaria is a parasitic infection transmitted by the Anopheles mosquito. Since both types of mosquito are prevalent on Nicaragua’s “Mosquito Coast,” anyone with a compromised immune system should not travel to this region, particularly during the rainy season.
All of the following, if true, strengthen the argument EXCEPT:
(A) Medicines taken to prevent or treat malaria can cause serious health complications for people with weak immune systems.
(B) The Nicaraguan government is trying to reduce the number of mosquitoes on the Mosquito Coast.
(C) A compromised immune system has difficulty fighting either viral or parasitic infections.
(D) During the rainy season, the populations of both Aedes and Anopheles mosquitoes multiply in the Mosquito Coast.
(E) The most effective chemical insect repellent has been shown to cause brain damage upon repeated application to the skin.
