Question 61

How would crowded conditions in cities favor spread of plague?

A)Plague is transmitted by rats-more people means more waste, and more waste means more rats.This would favor the spread of plague.
B)Plague is transmitted by mosquitoes-more people close together gives an infected mosquito more chances to bite humans and transmit the causative agent, spreading plague.
C)Plague is transmitted by infected fleas-these fleas may be found on rodents (such as rats).More people in an area means a greater chance of interactions with animals carrying infected fleas, increasing the spread of plague.
D)Plague is transmitted by direct contact (e.g.skin to skin).More people in an area provides more chances for infected individuals to directly contact and infect other individuals, spreading plague.

Question 62

Why does it take more than a week before a mosquito just infected with yellow fever virus can transmit the disease?

C)Yellow fever is caused by a protozoan.It must develop from the sporozoite form into the mature form to become infectious, and this takes time.
D)The virus multiplies in the gut of the mosquito, but then needs to migrate to the proboscis (biting nose) of the animal in order to infect a new human being after a new bite.This migration takes time.
