(2/5) Why has the doubling time shortened?
(1) more contacts than last month (schools, workplaces, etc.)
(2) test turnaround time is increasing, so case management & contact tracing starts later
(3) so, people mix with others, without knowing they are infected

But it's not just on us as individuals.
