Given the importance of the recent Zika outbreak, I decided to perform some analysis on how the virus is spreading. I found very good data about Puerto Rico, so decided to focus there. With data from each municipality in Puerto Rico, it is possible to find a connectivity map of the island according to how the virus spreads there. By analyzing the growth of cases over time in each municipality treat them as independent series and performing correlation analysis, we have that the most relevant connectivity groups are given by the following graph. There are 5 clear connectivity groups based on their response to the virus, Group 1 Group 2 Group 3 Group 4 Group 5 And the strongest connectivity is given by the following graph, This connectivity is given by an adjacency matrix obtained by calculating the r² coefficients among the municipalities. In this graphs are displayed only the strongest r² coefficients.
