Why is the Spread of Vector-Borne Diseases Increasing?

Several factors contribute to the increased spread of vector-borne diseases:

- Climate change: Warmer temperatures and altered precipitation patterns create ideal conditions for vectors to thrive and expand their geographical range. For instance, warmer climates allow mosquitoes to survive and breed in previously inhospitable regions.
- Urbanization: Rapid urban growth often leads to inadequate housing, poor sanitation, and stagnant water bodies, which are perfect breeding grounds for vectors like mosquitoes.
- Global travel and trade: Increased movement of people and goods facilitates the spread of vectors and the pathogens they carry to new regions.
- Ecological changes: Deforestation and changes in land use can disrupt ecosystems, leading to increased vector populations and closer human-vector contact.
- Resistance: Both vectors and pathogens can develop resistance to insecticides and drugs, making control and treatment more challenging.
