[MGLQZ]

Tent communities are constructed in a rural community by the American Red Cross after a disaster. Because of overcrowding, surrounding states create accommodations for the displaced and homeless.
 
  The survivors are accommodated in the cities of four Southern states. Which factors may increase the possibility of disease emergence in the cities? (Select all that apply.)
  A) Poor hygiene
  B) Decreased socialization
  C) Poor sanitation
  D) Decreased viral load
  E) Increased violence

Question 2

Which environmental factors are likely to affect the life cycle of disease pathogens and their vectors and thus disease outbreaks? (Select all that apply.)
 
  A) Temperature
  B) Geology
  C) Precipitation
  D) Humidity
  E) Amount of daylight

Answer to Question 1

Ans: A, C
Feedback:
Urban life, with malnutrition, overcrowding, and poor sanitation, enhances the major pathways for transmission of infectious disease. The forced dislocation of large groups of people and migration of such groups of people from rural areas to cities can be accompanied by a breakdown of public health measures, leading to poor hygiene. These have often been factors in disease emergence. Decreased socialization, decreased viral load, and increased violence would not tend to increase the likelihood of disease emergence.

Answer to Question 2

Ans: A, C, D
Feedback:
Many infectious diseases have characteristic geographic distributions and seasonal variations. Probably the most common is the influenza virus, which peaks each fall and winter. Factors such as temperature, precipitation, and humidity affect the life cycle of many disease pathogens and their vectors, and consequently they can affect disease outbreaks. Geology, or the types of rocks present in the area, and the amount of daylight are not likely to affect the life cycle of disease pathogens and their vectors.
