Can I ask a really stupid question as I can't seem to find the answer? Although we've been in lockdown since Monday 23rd March, why are current infection rates still so high? How are these people still becoming infected in such alarming numbers? Especially since we have been told the incubation period is 14 days and he vast majority of the population have been following government advice on isolation/social distancing etc.? I am genuinely perplexed. Thank you.
