Does urbanization contribute to the spread of Zika Virus Infection?
Urbanization is a key factor in how many diseases spread. For viruses like Zika, which are carried by mosquitoes (arboviruses), the growth of cities changes the environment in ways that help the virus move from one person to another.
What the research says
Accelerated urbanization is identified as a social and environmental factor that transforms habitats for arthropod vectors 1. These vectors are the insects, such as mosquitoes, that carry and transmit viruses like Zika to humans. When cities grow rapidly, they can create conditions that favor the survival and spread of these insects 1.
The primary mosquito responsible for spreading Zika is *Aedes aegypti* 57. This specific species is highly successful because it prefers urban environments and stays in close proximity to humans 7. Because *Aedes aegypti* can thrive in city settings, urbanization provides a stable environment for the mosquito population to grow, which in turn facilitates the spread of Zika infections 17.
What to ask your doctor
- How do local environmental factors or urban conditions affect the risk of mosquito-borne illnesses like Zika?
- What are the most common mosquito species in my area that carry viruses like Zika, Dengue, or Chikungunya?
- What steps can I take to reduce my exposure to mosquitoes in both urban and rural settings?
