Looks great! How will you distinguish between locally acquired vs. travel acquired cases moving forward? Simple, clear data visualizations are critical for communicating risk to the public, this is great! Another fantastic news source for Zika updates is STAT news:
My organization, the Skoll Global Threats Fund, as worked with tech firms in several countries to develop a 'participatory disease surveillance' model - essentially crowdsourcing symptom reporting for the general public as an early warning mechanism against outbreaks. In Brazil, an organization called Epitrack - http://www.epitrack.com.br/ - used this approach for mass gathering surveillance during the World Cup in 2014 and are deploying a new application 'Guardians of Health' soon for the Olympics.
Adding the 'check-in' feature to applications like these could add real value for vector surveillance, allowing the general public to report on mosquito activity, note whether a location has control measures implemented, etc.
I loved this idea from the prototyping event... I think the most powerful aspect of this approach is the 'buy one, give one' model that could tap heavily into the Brazilian tourism industry and especially the Olympics travelers. While a lot of organizations will be attempting to push out these kind of supplies, having them organized into a kit to avoid redundancies, and accompanied by a funding model that could scale distribution could be quite effective.
