Vector-borne Diseases: Global Trends and Local Implications

Abstract

Larsson Anette

Vector-borne diseases have long been a concern for public health. They are caused by a variety of pathogens, including viruses, bacteria and parasites and are transmitted to humans through the bite of infected vectors. Climate change, urbanization and global travel have contributed to the changing landscape of these diseases. Vector-borne diseases collectively account for a substantial burden of illness and death worldwide. According to the World Health Organization (WHO), vector-borne diseases are responsible for over 17% of all infectious diseases and contribute to more than 700,000 deaths annually. Several vector-borne diseases have gained prominence due to their global impact. Transmitted by Anopheles mosquitoes, malaria affects millions of people each year, particularly in sub-Saharan Africa. A viral disease transmitted by Aedes mosquitoes, dengue has become a growing concern in many tropical and subtropical regions. Also transmitted by Aedes mosquitoes, Zika gained attention due to its association with birth defects and neurological complications. Spread by ticks, Lyme disease is prevalent in parts of North America, Europe and Asia. Another disease transmitted by Aedes mosquitoes, Chikungunya has caused outbreaks in various regions. These include diseases like Rocky Mountain spotted fever, which are transmitted by ticks, mites, or fleas.
