Global Control of Vector-borne Diseases

Diseases like the Zika virus and the West Nile virus are evaluated and worried over by the world.  The threat of Zika making it to the United States caused great concern this past summer.  Luckily for the States we only had travel-related cases until the very end of the summer.  Vector-borne and zoonotic diseases have been emerging as great problems for the world.  This is another part of the history of disease changing.  Concern for these diseases started appearing in the past three decades (Kilpatrick & Randolph, 2012).  My experiences at the Montgomery County Health Department taught me how much effort can go into vector control programs.  In that county, we set traps to catch and identify different types of mosquitoes.  We sent these mosquitoes off to the Indiana State Health Department to be further tested for disease.  West Nile virus has been located in Montgomery County.  Using adulticide spray and larvicide dunks, we tried to control the problem before it got out of hand.  I wanted to know what new steps the world is taking at large to gain control over the vector-borne diseases.  Kilpatrick and Randolph make the argument that clinicians are just as important as epidemiologists for the control of these outbreaks.  Once the disease has been defined, it is the clinician’s job to properly and quickly identify the disease.  We are more often seeing these diseases spread from human to human hosts.  Examples of this are dengue fever and malaria.  The Zika virus has also been known to be transmitted by sexual contact.  This is why it is so important for clinicians to understand and diagnose the diseases in an efficient manner.  The clinicians and epidemiologists face the difficult task of separating out the different vector-borne illnesses because of their similar symptoms.  This is one method of vector control.  Other countries are looking more at fixing the problem at the source.  In China, they hope to prevent mosquitoes from being able to carry the diseases and thus prevent the spread.  Kilpatrick and Randolph agree that continued work needs to be done.  Developing countries are at a disadvantage because of lacking finances and technology.  Globalization is one of the reasons these vector-borne illnesses have spread.  It will take a global effort to maintain control over any more growth for these diseases.

  1. Hi Erin,

    I am glad you brought up globalization to the surface again. As I have been going through each week and as we are continuously being exposed to the numerous negative impacts that globalization has had on health around the world, I believe that we as public health professionals should understand that globalization is certainly not going to go away and will only be making our world even "smaller" in terms of what it will allow us to be exposed to whether that be different cultures or even different pathogens. To alter this, I believe that we should beat it at its own game! Use globalization as a primary tool and see it as a strength in carrying out interventions. This can certainly help improve access to information, access to education, which are essential to combating many global health problems. As seen in the Education-Entertainment model, leveraging globalization and using it as a model to move things forward instead of seeing it as a deterrent is one way in which we can reverse any negative aspect that it may cause. In the E-E model, technology and entertainment merge together to create awareness, to create a buzz and have a positive influence on health behavior practices. Perhaps taking the very same approach can be a way to combat such illnesses.
