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.
Researchers at HealthMap just published work on Zika in Colombia here: http://publichealth.jmir.org/2016/1/e30/
Having worked with HealthMap on a number of projects, I think they would consider this type of approach but in outbreak scenarios it will be important to get government buy-in to ensure sharing of this type of data is done in a way that protects patient privacy and ensures coordination with outbreak responders.
