According to Eleazar, commander of the Joint Task Force (JTF) Covid Shield, the technologies are scalable for a selective or a total ECQ implementation. One technology is called Safe Paths, a privacy-centered “rapid and unique” contact tracing app that utilizes global positioning system (GPS) and Bluetooth proximity technologies, Eleazar said. When an app user contracts the coronavirus disease 2019 (Covid-19), he or she submits his or her location tracking to the Department of Health (DoH). Other users of Safe Paths receive color-coded status alerts whenever they come in contact with an infected user, bared Eleazar. A green circle means no close contact, and a yellow one means close contact with a Covid-positive user, requiring self-quarantine or testing for Covid-19 “if they have symptoms,” Eleazar elaborated.
