How Would Crowded Conditions in Cities Favor Spread of Bubonic

question 47

Multiple Choice

How would crowded conditions in cities favor spread of bubonic 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 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.
• C) 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.
• 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.
• E) Bubonic plague is transmitted by aerosol droplets. People in cities are always dependent on public transport, which is typically overcrowded, so are at risk of acquiring plague bacteria.
