Vectors which transmit these diseases
A vector is a living organism which transmits an infectious disease between humans, or from animals to humans. Such vectors include:
- Aquatic snails
- Black flies
- Triatomine bugs
- Tsetse flies
Preventing vector-borne diseases
- There are an estimated 96 million cases of dengue fever annually, with 3.9 billion people across 128 countries at risk.
- More than 400,000 deaths are caused each year around the world by malaria. A majority of these are among children under five  years of age.
However, many vector-borne diseases can be prevented through informed protective measures.
The World Health Organization [WHO] offers strategic guidance to its development partners and to countries, under the Global vector control response [GVCR] 2017-2030 in an attempt to prevent diseases and properly respond to outbreaks.
Simple measures can be taken to avoid most vector-borne diseases in areas where they are prevalent. These include:
- Receiving relevant vaccinations, and ensuring they are up to date.
- Wearing light-colored clothes – long-sleeved shirts, and long trousers tucked into shoes or socks.
- Using insect repellents on clothing and exposed skin.
- Installing window screens at home and the workplace.
- Sleeping under insecticide-treated bed nets.
- Checking the body regularly for ticks.
- Maintaining strict personal and food hygiene.
- Avoiding contact with blood, bodily fluids, organs, and/or secretions of infected animals and people.
