Air travel and vector-borne disease movement

Area of Science:

• Epidemiology
• Public Health
• Geospatial Analysis

Background:

• Global air travel has significantly expanded, increasing traffic volumes.
• While the spread of directly transmitted infections via air travel is understood, its role in vector-borne disease transmission is less clear.
• Advances in disease surveillance and vector mapping offer new insights into air travel's impact.

Purpose of the Study:

• To examine global air transport expansion and its epidemiological impact.
• To investigate the role of air travel in the movement of vector-borne diseases.
• To develop a tool for predicting vector-borne disease importation risks.

Main Methods:

• Analysis of global air transport trends and epidemiological data.
• Case studies of malaria and chikungunya importation.
• Integration of geospatial data with air traffic information.
• Development of the Vector-Borne Disease Airline Importation Risk (VBD-Air) tool.

Main Results:

• Air travel expansion poses a risk for the importation and establishment of vector-borne diseases.
• Geospatial and air traffic data can predict disease importation risks.
• The VBD-Air tool quantifies seasonal risks of vector-borne disease importation to non-endemic regions.

Conclusions:

• The VBD-Air tool represents a framework for assessing vector-borne disease importation risks.
• This approach facilitates adaptive management strategies integrating flight data and disease surveillance.
• Improved understanding of air travel's role in disease spread is crucial for global health security.
