Could tethered drones be used to help deal with Ebola?

Helen Greiner's company CyPhy Works makes tethered drones which can survey an area 24 hours a day, seven days a week.

The tether can send video and audio information to and from isolated victims via the drone, and could one day make deliveries. It could also be used to create a communications network if there wasn't one available.

Helen Grenier explained to Click's Jen Copestake that as the technology develops the drones could be used to help in a situation like an Ebola outbreak.
