I thought this recent articles by Bernard Marr in Fordes on 9th April was rather interesting.

"One of the advantages we have today in the fight against coronavirus that wasn’t as sophisticated in the SARS outbreak of 2003 is big data and the high level of technology available. China tapped into big data, machine learning, and other digital tools as the virus spread through the nation in order to track and contain the outbreak. The lessons learned there have continued to spread across the world as other countries fight the spread of the virus and use digital technology to develop real-time forecasts and arm healthcare professionals and government decision-makers with intel they can use to predict the impact of the coronavirus.

China’s Surveillance Infrastructure Used to Track Exposed People

China’s surveillance culture became useful in the country’s response to COVID-19. Thermal scanners were installed in train stations to detect elevated body temperatures—a potential sign of infection. If a high temperature was detected, then the person was detained by health officials to undergo coronavirus testing. If the coronavirus test came back positive, authorities would alert every other passenger who may have been exposed to the virus so they could quarantine themselves. This notification was enabled because of the country's transportation rules that require every passenger who travels on public transport to use their real names and government-issued ID cards.

China has millions of security cameras that are used to track citizens’ movements in addition to spotting crimes. This helped authorities discover people who weren’t compliant with quarantine orders. If a person was supposed to be in quarantine, but cameras tracked them outside their homes, authorities would be called. Mobile phone data was also used to track movements. "

In terms of how many countries have faired in there management of this pandemic it is fair say that those countries such as, Germany, Australia nad USA that have a federal system as well as semi-autonomous state systemfor example have found it much harder to achieve concensus when it comes to agreed actions to compating this pandemic. Nobody actually wants the ultra high levels of personal surveillance that the peoples of china have it is fortunate that that data could be used for good use on this occasion.
