EPIPOI was developed by Wladimir J. Alonso using Matlab.

EPIPOI can be downloaded, used and distributed for free. I only request that the following reference is used in those analyses, figures and didactic material generated with the assistance of EPIPOI:

Alonso WJ  &  McCormick BJJ 2012 A user friendly analytical tool for extraction of temporal and spatial parameters from epidemiological time-series.  BMC Public Health 12:982


Special thanks to:

  • Daniel Yukumura contributed with the implementation of several improvements in Epipoi
  • Benjamin J. J. McCormick implemented the function for the Fourier analysis and helped in the writing of the manuscript that described the program.
  • Cynthia Schuck-Paim implemented this webpage using WordPress and the Nova Theme
  • Jie Zhang (Jack) helped us to compile the Mac version of Epipoi.

Financial support for the development of the program and the epidemiological analyzes and by the author was provided by:

  • Prêmios Santander Universidades, which supported the development of a user-friendly program for the visualization of data and implementation of epidemiological analyses.
  • MISMS Study, a international collaborative effort to understand influenza epidemiological and evolutionary patterns, led by the Fogarty International Center, National Institutes of Health.


The following references describe specific analyses in more detail. We suggest them both for consultation and citation

Wavelet Analysis:

Periodic Regression:



I appreciate any feedback as it is essential to keep improving future versions of the program.
