Area of Science:

  • Epidemiology
  • Computational Biology
  • Mathematical Modeling

Background:

  • Chikungunya virus (CHIKV) poses a significant public health threat globally.
  • Understanding CHIKV transmission dynamics is crucial for effective control strategies.

Purpose of the Study:

  • To develop and implement a mathematical model simulating the spatiotemporal spread of Chikungunya.
  • To incorporate realistic factors influencing disease transmission, such as population density and environmental variables.

Main Methods:

  • A C++ cellular automata code on unstructured triangular grids was developed for the spread model.
  • Geographical Information Systems (GIS) were used to define localized infection points.
  • Simulations incorporated heterogeneous human/vector densities, population mobility, and environmental factors affecting mosquito lifespan and infection probability.

Main Results:

  • Numerical experiments successfully reproduced the qualitative behavior of Chikungunya spread.
  • The model provides insights into the impact of various factors on disease transmission patterns.

Conclusions:

  • The developed mathematical model is a valuable tool for understanding and predicting Chikungunya spread.
  • Findings can inform the development of targeted public health interventions and prevention strategies.
