Coronavirus tracing apps: False hope and hidden dangers?

Nations try to track and trace their way out of the corona crisis. Some see apps as essential. But so far apps have had limited success. Australia’s has picked up only one case in a month. And privacy concerns remain, with a citizen’s every move being monitored. Not everyone is keen on installing a tracing app on their phone. But in countries such as India, there’s little choice.The Indian government has released a contact tracing app and people there must download the state-backed app if they want to travel. Some countries, like Japan, appear to have fought off the virus without the help of such technology.
