Tech is not going to fix this, say software experts from tech companies. Google and Apple's efforts in coming up with an app have fizzled out, says this report in thee WSJ. Has the U.S. lost precious time in waiting for an app by tech companies to be developed, instead of doing what India and Britain have done. India introduced its own app Aarogya Setu app from the Indian government. Britain had the National Health Service develop its app. India acted quickly.

Is an app needed or essential? Germany decided that contact tracing based on Asian country experience was mainly about human contact tracers with skills to make the phone calls. All they needed was a centralized database on a computer and a phone. Germany set up teams at offices in each district in Germany and quickly plodded ahead even if all the offices were not fully staffed. In fact a third of the offices needed more people and resources. Yet the speed of action is something like 80 to 90% of the contact tracing effort when the team has the skill set to call. This is because clusters of infections do not wait - they spread. There is simply no time to waste. The German effort has produced the best results so far of any country of this size- Germany has 85 million people. The reproduction ratio is at 1.13 and Germany remains vigilant. It is the first country to reopen in Europe, and is methodically doing the right actions, much that the world can and should learn from. Contact tracing teams worked round the clock in the early days, they are still hard at work today, using their human skills to talk to people and find out who they were in contact with, calling the contacts in turn, at each step working to isolate where needed with followup calls from the state health departments.
