He and his staff when compared new circumstances of COVID-19 right before and up to 30 days right after the introduction of physical-distancing measures, this kind of as restricting massive gatherings and closing universities, workplaces and community transit.

On average, this kind of measures had been carried out nine days right after the to start with claimed situation of COVID-19. Having said that, some international locations took for a longer time to apply measures, which includes Thailand (58 days), Australia (fifty one days), Canada (forty six days), and Sri Lanka and the United Kingdom (45 days).
