Question 11

How would increased travel lead to increased spread of multicellular eukaryotic parasites?

Accepted Answer

A) Many eukaryotic parasites are transmitted directly from person to person via airborne transmission-so getting an infected individual onto a plane of susceptible individuals would increase spread. 
B) Many eukaryotic parasites depend on vectors (often small blood-sucking insects)for transmission-so moving an infected individual into an area with new populations of vectors and new susceptible humans would increase the spread of the illness. 
C) It really would NOT-most individuals are screened for parasitic infections prior to traveling out of highly infected areas.We also have quarantine abilities at customs stations for individuals entering the United States. 
D) Eukaryotic parasites are too small to travel great distances effectively-by hitching a ride on luggage,clothing,fruit/vegetables,and other food products,they can enter new geographic areas.
