What is the difference between South Korea and the U.S., Europe in the handling of coronavirus? It is tracking and testing. President Trump and health adviser Dr. Fauci, see South Korea as the successful model to be followed in controlling the coronavirus. What has happened till now it is accepted with shortage of basic medical supplies and equipment, stress on hospital systems, are merely mitigation actions. South Korea was prepared for the coronavirus crisis because of the MERS and other epidemics, and failures resulting in corrective actions. Labs were centralized and better equipped for testing and tracking the infected. One of the key tools is testing. President Trump says the goal is for the U.S. to exceed and far surpass tests per capita in South Korea. Five million tests are planned by the end of April in the U.S. Where the U.S. falls short is in use of multipronged digital tracking using data from people's use of mobile phones, credit card usage, and use of apps designed to separate infected people from others. South Korea is a democracy with a population of 52 million people, about the size of France. People who were student activists in the democratization era in South Korea say the use of digital technology is a need today. We have to adapt in emergency situation they say. Ki Mo-ran, epidemiologist, and adviser to South Korean government says this is a key part lacking in the European and U.S. efforts to control coronavirus. She says in South Korea we know the patient's contacts, where he goes and stays, so we don't have to lock down everybody. Without digital tracking one cannot know which place is contaminated, which place is clean, so that there can be a lockdown of just that area and not the whole country, says Ki Mo-ran. She asks the question- is one person's privacy more important than the lives of a family or other people who are affected. Is it OK to lockdown every child in the country in a home as in Spain for over a month so that particular people's privacy is respected? These are serious questions for western society, are they exceptions or is democracy not just a western idea but equally cherished in Asian societies, people talk about Confucianism in China and the Asian culture forgetting that the biggest democracies are quite large and functioning well in India in addition to South Korea, Taiwan Indonesia, Malaysia, Bangladesh and Japan, far larger in area and population than China. The French government has chosen the app TraceTogether as the least intrusive one adaptable to France for use there. The U.S. is having Google and Apple develop one of its own. India will be developing one of its own. The NYT raises the question will it be watered down so much in France or in the U.S. and UK to be less effective than the dire need for an alternative to lockdowns? ...
