What Are Vector-Borne Diseases?

Vector-borne diseases are illnesses that are transmitted through contact with an infected animal or insect bite. These vector-borne diseases, also known as vector-borne infections, are some of the most common infectious diseases. Some examples include Lyme disease, West Nile virus, malaria, and Zika virus.

How Are Vector-Borne Diseases Transmitted?

Vector-borne diseases are transmitted when an infected animal, such as a mosquito, ticks, or flea bites an animal or human and transmits a disease-causing pathogen. These infected animals, called vectors, can also spread the disease to other animals and humans.

How Does Climate Change Affect Vector-Borne Diseases?

Climate change affects the spread of vector-borne diseases by altering the habitats and behaviors of vectors. Warmer temperatures can enable vectors to thrive in different areas, increasing the risk of exposure to infected animals. This can lead to an increase in the number of vector-borne diseases and more chances of being bitten and infected.

How Can We Protect Ourselves from Vector-Borne Diseases?

Protecting ourselves from vector-borne diseases begins with understanding the relationship between climate change and vector-borne diseases. We can reduce our risk of exposure to infectious animals or insects by taking prevention measures such as:

  • Using insect repellent
  • Wearing protective clothing
  • Staying indoors at dusk and dawn
  • Covering windows and doors to keep insects out of the house
  • Removing standing water, which serves as a breeding ground for mosquitoes
  • Getting screened for vector-borne diseases
  • Maintaining good general health

Understanding the environmental impacts of vector-borne disease and how to protect ourselves from them is essential for public health and safety. By adhering to these prevention strategies, we can reduce our risk of contracting vector-borne diseases.
