Interesting:
"It was agreed that a combination of case isolation, household isolation and social distancing of vulnerable groups is very unlikely to prevent critical care facilities being overwhelmed. "
"It was agreed that the addition of both general social distancing and school closures to case isolation, household isolation and social distancing of vulnerable groups would be likely to control the epidemic when kept in place for a long period. SPI-M-O agreed that
this strategy should be followed as soon as practical, at least in the first instance.
It was agreed that a policy of alternating between periods of more and less strict social distancing measures could plausibly be effective at keeping the number of critical care cases within capacity. These would need to be in place for at least most of a year. Under such as policy, at least half of the year would be spent under the stricter social distancing measures"
(Emphasis mine, from SPI-M-O: "Consensus view on behavioural and social interventions") assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/873729/06-spi-m-o-consensus-view-on-behavioural-and-social-interventions.pdf
So we have now had the school closures, I think today we will have the "general social distancing" added, whatever that means.
