South Korea's response to Covid-19 has been widely praised. The reason for their success is contact tracing. They have been able to quickly identify people exposed to the virus and the citizens comply with a 2 week quarantine to stop the spread.
WHO says the lockdowns are a good tactic in situations where the transmission is spiralling out of control and a threat that the health system will be overwhelmed. But they should not be used as the main strategy and the decision should be considered carefully.
I am in favor of adopting Japan's strategy, which has proven most effective in the fight against super-spreaders. The Japanese didn't impose a strict lockdown during the first wave, but they were roughly as successful as we were. That is exactly what we need for the second wave. The virologist Christian Drosten (one of Germany’s leading figures in the COVID-19 crisis) also sees this strategy as the correct course of action.
Sweden's controversial decision not to impose a strict lockdown in response to the Covid-19 pandemic led to too many deaths, the man behind the policy, Anders Tegnell, has acknowledged.
Shutdown orders prevented about 60 million novel coronavirus infections in the United States and 285 million in China, according to a research study published Monday that examined how stay-at-home orders and other restrictions limited the spread of the contagion.
With more than a third of the world’s population in lockdown, there are widespread fears of social breakdown. As a historian of loneliness, I have recently been interviewed by journalists in Brazil, France, Chile and Australia, all pondering the same problems: what will the long-term effects of social isolation be? What techniques or habits might help us learn how to be alone?
Brits express more apprehension about easing the lockdown than any other major country, according to a recent Ipsos MORI poll that surveyed some 28,000 people across 14 different countries. That includes places like the US and Italy, which have both a higher number of Covid-19 deaths and confirmed coronavirus cases.
The problem, experts say, is that diagnostic testing remains so limited that a second surge of cases could silently build. The Trump administration’s goal of conducting 2 million tests a week is below what most experts say is needed to adequately track the virus, and that plan won’t be in place until at least the end of May.
Researchers are using mobility data prior to the lockdown, and comparing it to the current mobility numbers to determine how to emerge from the lockdown without triggering major resurgence in the outbreak. The researchers admit that their conclusions are highly uncertain and more data is needed.
