From yesterday's New Scientist
From your link-
"[David] King who last month launched an independent alternative to the government’s scientific advisory group, says that while differences in culture, demographics and data collection can make international comparisons hard, they cannot explain the gap between the UK and countries including Australia, Greece and South Korea."
I can help him out with South Korea - Keir Starmer and Yvette Cooper say we should track and trace like South Korea:
"25 March SEOUL (Reuters) - South Korea warned on that it will deport foreigners while its citizens could face jail if they violate self-quarantine rules after a surge in imported coronavirus cases."
"The success behind South Korea’s fast action toward containing the spread of COVID-19 is in its legal access to private information of credit card transactions, according to observers on Wednesday [April]. Despite disputes on infringing on individuals’ privacy, the method is being touted in and out of the country for its efficiency, as it can take just 10 minutes to track the movement of patients infected with the virus."
"Since the first case of the novel coronavirus was confirmed on Jan. 20, the Korean government has traced infected patients’ routes and identified who might have come into voluntary or non voluntary contact by looking into credit card records. Authorities have publicized some of the records as part of containment efforts."
