Via the website Health Intelligence (which is in my Bloggers list): Zika Virus Disease Outbreak in Colombia: A Tool for Monitoring Cases. This is a very effective use of graphics to provide an overview of the situation. You'll find similar dashboards for Zika and microcephaly in Brazil as well as a map showing worldwide distribution of Aedes aegypti and A. albopictus. And dig back still further and you'll find highly useful posts on a very wide range of public health issues. Highly recommended, and I'm mortified that I didn't pick up on this site years ago, even though I first linked to it in 2014.
