Controlling biting-insect populations is an issue that greatly affects the entire global community. Over the years, the World Health Organization and other bodies within the United Nations have attempted to control insect populations, treat illnesses, and educate the world as to how biting insects affect humans and animals day-in and day-out. In order to further understand the issue at hand, we must define the cause and understand the effect. Biting insects are commonly referred to as vectors. Vectors are living organisms that can transmit infectious diseases between humans or from animals to humans. Though we primarily focus on the transmission of disease from these insects to humans, animals and their role in the sustainability of life for humans should not be ignored. The most commonly known vector is the mosquito; however, there are multiple types of flies, ticks, fleas, and even aquatic snails that can spread disease and illness. These insects contribute to the spread of malaria, yellow fever, Lyme disease, West Nile virus, dengue fever, and even the plague; just to name a few.
Here are some key facts outlined by the WHO to consider. Vector-borne diseases account for more than 17% of all infectious diseases, causing more than 1 million deaths annually. More than 2.5 billion people in over 100 countries are at risk of contracting dengue fever alone. Malaria causes more than 600,000 deaths every year globally, most of them children under 5 years of age. Many of these diseases are preventable through informed protective measures, including bed nets. The approach to combating vector-borne disease requires focus on environmental and social behaviors within a population, as well as systematic cultural adaptation and education of said populations to ensure that they are able to treat and prevent potential outbreaks. This can range from the most industrialized nations to the developing world. The uniqueness of each disease and its vectors that carry them can be introduced to any population, given the world of travel we live in today.
The WHO partners with many other organizations such as the Food and Agricultural Organization (FAO) and U.N. Environment Programme (UNEP). These organizations, along with many others, combat illness and disease in our food supply by discussing and implementing treatment plans for fruits, vegetables, meats, and seafood. Whether it is the use of pesticides and other chemicals to prevent contamination, eradicating vectors from its food supply, or properly and sustainably storing harvested foods without contamination from vectors, it is clear that a broad-based approach will be necessary. This approach is being complicated by the rise of pesticide-resistant strains of insects, which will need to be addressed if the problem is to be solved. Beyond the question of food is how to protect individuals from insects that are not directly connected to the food supply, mosquitoes being the obvious example. While bed nets are a cheap and effective tool for protecting children and adults as they sleep, they aren’t exactly a portable solution. At-risk individuals must be protected during waking hours as well.
Focus Questions:
* What illnesses or diseases related to biting insects are prevalent within your country?
* What steps has your country taken to effectively manage cases and outbreaks stemming from vectors? What role has your country played in supporting other nations in your region or across the globe with similar outbreaks (large or small)?
* What reporting systems does your country have and do they capture the true burden of the disease within your country?
* What training/treatment systems does your country have to combat vector-borne disease? How can these systems be of help to all nations?
* What tools has your country used or developed to combat the vectors and deal with the disease?
* What Non-Governmental Organizations (NGOs) have played a role in vector-borne disease and illness prevention?
