The COVID-19 pandemic and contact tracing technologies, between upholding the right to health and personal data protection

Countries responded to the COVID-19 pandemic with various levels of restrictions and lockdown in an effort to save lives and prevent the saturation and collapse of national health systems. Unfortunately, the blockades have entailed hefty socioeconomic costs. In order to contrast the spread of the virus, states have used contact tracing technology, in the form of mobile phone applications designed to track close contacts of those infected with COVID-19. Recent research has shown the effectiveness of this solution, particularly when used in conjunction with manual tracking. Nonetheless, the contact tracing app raises concerns due to the potential privacy implications. The authors have delved into the European legislation that protects privacy through the principles of proportionality and minimization, arguing that in order to quickly resolve the pandemic caused by COVID-19, one cannot blindly trust the exclusive help of technology. Instead, we need the involvement of health personnel, scientists, and no less importantly, the citizenry's sense of solidarity and the duty to abide by the rules of social distancing, the use of protective devices and hygiene rules to protect public health.
