Angela Merkel said that contact tracing was "above all else" in importance in tracking down infection chains. Apps would not work in Germany because tracking movements and recording information is a sensitive subject in Germany with its history of communism and fascism. Germany still did it but very early on adopted a low tech way that so far is working. Staff from provincial administrations have shifted to do contact tracing work as other work is slow or suspended. Volunteers also have taken up the work. Germany's goal is 5 contact tracers for every 25,000 people- or about 16,000 for a population of 83 million. All the contact tracers have is the phone and a central database of information on the desktop computer as shown here in this report in the Washington Post. There is no advanced technology or software. Most important say experts is social skills - to talk to people in a way that makes them feel comfortable to share information about how they are and their contacts in a very informal friendly setting, that even includes some humor. Here a contact tracer in Reinikendorf describes the work she is doing and a typical day. There are about 75 contact tracers for 260,0000 people in her area. When she calls someone she notes down what contacts they have had and puts them in Category 1, 2 , or 3 depending on the need for quarantine. The calling is mainly about asking the contact about his or her movements. A contact for more than 15 minutes is Category 1, less than 15 minutes Category 2. The whole conversation is for 10 minutes. Then someone from the health department will call the person contacted everyday. Reickendorf began building up contact tracing in March after an outbreak in a kindergarten was too much for the usual number of health officials to handle. The German trace and quarantine approach, home grown, low tech, and based on what resources are available, the most important thing being start immediately, has its flaws. Yet it has worked to limit infections and deaths. In about 65% of cases health authorites have no idea how a person was infected. Asymptomatic carriers are not detected. In some area the resources are limited. This effort has helped control the virus first cluster in Bavaria at a car part manufacturer. Sixteen people had tested positive and hundreds were quarantined. The German approach is that testing is fine but if you are in quarantine testing is not going to make a difference in spreading. Testing with a negative result is also not helping as it could be that its too early for the infection to register because of the incubation period. ...
