so i'm going to hand over to saundra if our men and the what is out to help us track of it 19, quantify covert 19. there's an app for that crucial recognition g.p.s. glue to make it easy. cameras and drones keeping honest to this is a kind of mortar should be banned. surveillance is really spreading everywhere. it's all about tracking people to contain the spread. but some want to know who's policing the police doctrine as adults in terms of technology and what's possible, what if you see what is exciting for yes, from my standpoint, looking at it from the public health response is missing. when we talk about contact tracing, the role for technology could be very big in that. now i'll preface by just saying that privacy is a 1st and foremost consideration and the technology should not be used unless that can be assured. but from a standpoint of trying to contact trace, when people are moving around again as, as countries and as places start reopening, if somebody is found to be positive, it becomes very difficult to figure out who exactly was around them and who may have been exposed. y
