The methodology of the study is fairly standard. It uses basic reasoning, supported with conclusive data to make its point on the true and falsehoods of communicable diseases associated with natural disasters.
The World Health Organization (WHO) has referenced this study in several places, namely on this powerpoint on natural disasters. (http://www.who.int/diseasecontrol_emergencies/publications/idhe_2009_london_natural_disasters.pdf).
Research Gate, a journal library, has an article entitled “Infectious diseases following natural disasters: Prevention and control measures” which also references this study. (https://www.researchgate.net/publication/51860057_Infectious_diseases_following_natural_disasters_Prevention_and_control_measures)
There are several ways that this study can benefit technical professionals. By knowing the factors for the highest risk for communicable diseases, resources can be directed to mitigate the effects of a disaster. The more aware technical professionals are of the risks of communicable diseases, the more likely they will be able to identify when these situations are likely and prevent them from happening.
This study addresses vulnerable populations by identifying the factors are that make one vulnerable. These factors are: loss of shelter, location of housing, access to clean water and sanitation, disruption to utilities, environmental changes, population displacement, health services, and response systems.
The study was funded by the CDC which is a government organization of the United States of America.
