Governments must choose from multiple anti-contagion approaches that have varying levels of effectiveness and intrusiveness. While it is ideal to implement approaches that are the least intrusive and most effective, unfortunately, sometimes there has to be a trade-off between effectiveness and intrusiveness. For example, a measure may be more effective, but far more intrusive; while others maybe not only less intrusive but also less effective (Gerards, 2013). It has been proven in practice that the more privacy-intrusive movement tracking apps are more efficient at containing the spread o the virus as it is possible to monitor in a centralized manner which individual has been in contact with whom, track and instruct one immediately, and monitor one’s quarantine. Hence, the question of what an acceptable trade-off between public health and privacy is comes down to a cultural context, and how much individual rights are valued over public good, or vice versa.
