TRACING CALL CENTER
The purpose was to build TRACING CALL CENTER
in order to
- decrease R0 of the epidemic using targeted, data-driven testing
- to be able to shift to “smart quarantine” from current countrywide lock-down
- dramatically decrease the negative economic impact of COVID19
How it works?
Flow 1
Whitelist of numbers of infected people to be traced
Sanitary station forwards the cell phone number of the infected person through a secure channel
Explicit Permission
Operator asks for explicit permission to use location data. This consent is audited and stored, shared with mobile operators and banks and is a prerequisite for the next step.
Data Generation
Operators and banks generate a set of location data on the movement and payments of this one mobile number / person. Dotmaps and heatmaps (Memory Map) is automatically created in CleverMaps
Memory Map Tracing
A trained and dedicated call center operator (trained medic) calls the infected person to find other suspected cases using the Memory Map. The resulting contact list is consulted with hygiene and further processed according to its recommendations, for example, to call with other information.
Flow 2
Whitelist of numbers of potentially infected people to be traced
System generates cell phone numbers of people who were in close proximity to infected numbers during the watched period
Explicit Permission
Operator asks for explicit permission to use location data. This consent is audited and stored, shared with mobile operators and banks and is a prerequisite for the next step.
Data Generation
System sends the number to telco operators and gets back a set of numbers which were identified as “appeared in the same cell during the given period with the number of infected person”. This only applies to numbers that are frequently used/called out of the infected number - i.e. covers mostly family, friends, co-workers,)
Notifications and Follow-ups
All these numbers get push SMS notification to get to sanitary station asap as they could have been in direct contact with infected person Verification calls - containing suspected cases to check if they have been tested
Cooperation with Covid19cz and Keboola
A current joyless period points out not only negative consequences that the Coronavirus has on our lives but also encouraging social phenomena. A huge wave of solidarity has awakened in the Czech Republic and among others the COVID19CZ initiative has been created. A group of IT companies felt that if they used their know-how when it comes to data process and modern technologies they could fundamentally help the country slow down the Coronavirus spread. The central activity of the initiative is the so called smart quarantine and memory maps that were created and are operated by CleverMaps and Keboola.
Technical and organisational solution
DISTRIBUTED
CALL CENTER
Provides the interface for obtaining consent of the end user for temporary usage of their data, in order to access the history and potential exposure information.
DATA
LAYER
Ensures connection and ingestion of data from the mobile operators, banks, apps etc., and access to the data by the CC operator.
ANALYTICAL
LAYER
Powers location-aware, map like interface for visualization of the exposure and contact data.
SMART
APPS
Gather anonymized contact data and providing a call to action channel to potentially exposed users.
Tracing of the infection in reality
There have been over hundreds of successful tracing calls and even during the first days the potential of the memory maps was demonstrated which could lead to the replacement of global state precautions and the ban to go out by smart quarantines. In order to make this happen the government must be involved in the process more and more sanitary stations throughout the Czech Republic need to me be established.
What does the work with the map look like? According to the size of the circle on the memory map, it is possible to determine how long the individual person stayed at the location. Only places where the infected person stayed for minimally 10 minutes are displayed.
