Epidemiologic Surveillance after Natural Disaster
Lesson 1 - Risk factors for communicable diseases after disasters
Study Guide
This lesson discusses epidemiologic factors that may determine the
potential transmission of communicable diseases after natural and manmade
disasters. It also provides an account of postdisaster experience with
communicable diseases.
Learning Objectives
Identify risk factors for communicable diseases after natural and
manmade disasters in both developed and developing countries.
Gain an overall understanding of postdisaster experience with
communicable diseases.
Learning Activities
Read pages 3-12 in the manual.
Study, but do not memorize, Table 1 in the manual.
Evaluation
Complete the Self-Assessment Test.
Notes

Multiple Choice
Circle the correct answer:
1. Increased population density is a critical factor in the
transmission of diseases spread by:
a. water
b. respiratory route
c. food
d.
person-to-person contact
e. b and d
True/False
Indicate T or F:
____2. Improved vaccination programs after disasters will prevent
the occurrence of vaccine-preventable diseases.
____3. In most of Latin America and the Caribbean, the classical
diseases associated with disasters have declined or disappeared.
____4. In a village with no electric power and where there are
promiscuous defecation habits and contaminated sources of water in normal times,
an increased risk from communicable diseases is likely after a disaster.
____5. The lack of baseline surveillance data between disasters in
developing countries makes no difference in confirming increases of certain
diseases.
____6. The risk of a spread of communicable diseases after a
disaster is about equal in developed and developing countries.
____7. Ecological changes due to a disaster may in some cases
reduce the risk of the spread of communicable disease.
____8. Laboratory diagnostic facilities for detecting communicable
diseases after disasters are not essential since the clinician or epidemiologist
can easily diagnose most communicable diseases.
