The pandemic has placed our elders at a formidable risk since age is the most significant risk 4 factor for severe morbidity and mortality [1] [2] [3] [4] . Consequently, some of the most challenging 5 situations occur in nursing homes (NHs) and assisted living facilities considered hotspots for 6 COVID-19. 7 In Israel, NHs and assisted living facilities were some of the hardest hit by COVID-19 5 . 8 Henceforth, a national task force appointed by the Israeli Prime minister named "Shield of 9 Fathers and Mothers", was appointed. 10 In order to aid the task force, we devised a novel, interactive, real-time, dashboard-based heat 11 map tool based on COVID-19 outbreak analytic metrics as well as spatiotemporal data analytics 12 (http://covid19maps.org/). We developed a novel platform, focused on assisted living facilities 13 and NHs, providing the Israeli Ministry of Health (MOH) policymakers with a national graphical 14 representation of all institutes (passkey protected to secure privacy issues). A basic layer, allows 15 to identify all facilities with diagnosed cases (resident or staff) by rendering them as "warm" ( 16 red color) if a positive COVID-19 case was identified within an interactive last n days (e.g. last 17 14 days as a default for the system) or "cold" (blue color) displayed in Figure 1A . Importantly, in 18 addition to basic layer that allow to represent the quantity of the diagnosed cases (displayed as 19 circle-size in the current platform), a key novelty of the developed platform is the ability to 20 follow and intuitively display the trajectories within the facilities where cases were identified.

The trajectories can be followed by using a set of mathematical analytic algorithms of evaluating
