Contact tracing apps: Which countries are doing what COVID19
PARIS - Several countries fighting the coronavirus outbreak are using -- or debating -- phone apps that trace a person's movements and who they come into contact with, allowing authorities to keep track of infections and alert people in case of contagion risk.
Their use was systematic and compulsory, and played a key role in allowing Beijing to lift the lockdown and halt contagions, with no new deaths reported since mid-April. This approach aims to address concerns of privacy invasions, particularly in Europe where officials have called for collaborative efforts that would include intense oversight to make sure users know when and how their personal data is being exploited.
In Hong Kong and Taiwan, which have managed to limit deaths despite their proximity to China, officials use GPS and Wi-Fi to keep strict tabs on people in quarantine. Despite the heavy death tolls, only a small percentage of the populations in many regions have been infected by the new coronavirus, meaning huge numbers of people would be at risk if the strict stay-at-home orders are eased and businesses and schools allowed to reopen.
