A two-week worldwide lockdown could significantly reduce Covid-19 transmission, but its effectiveness may be limited by the reality of symptomless spreaders and the potential for non-compliance among the population. While some argue that a lockdown could provide a temporary respite and allow for better preparation for future measures, others believe that repeated lockdowns would lead to diminishing returns and public fatigue. The discussion highlights the importance of vaccination rates, with some expressing skepticism about achieving the necessary immunity levels due to anti-vaccine sentiments. Successful strategies from countries like Taiwan and New Zealand emphasize the need for early interventions and strict border controls, which may not be feasible globally. Ultimately, the conversation underscores the complexity of managing the pandemic and the challenges of implementing effective public health measures.
