22 January – Poor data from China22 January – Poor data from China
In the first Sage meeting responding to the outbreak of coronavirus in Wuhan, the committee agrees there is considerable uncertainty around the data coming out of China, meaning “a reasonable worst case cannot be made reliably”.In the first Sage meeting responding to the outbreak of coronavirus in Wuhan, the committee agrees there is considerable uncertainty around the data coming out of China, meaning “a reasonable worst case cannot be made reliably”.
28 January – Test ready by end of week28 January – Test ready by end of week
The committee says a test for coronavirus should be ready by the end of the week, with a capacity to run 400 to 500 tests per day. It agrees on the importance of behavioural science informing policy. The committee says a test for coronavirus should be ready by the end of the week, with a capacity to run 400 to 500 tests per day.

3 February – Sage rejects travel restrictions3 February – Sage rejects travel restrictions
The committee considers imposing restrictions on travel into the UK. It concludes that reducing imported infections by 50% would maybe delay the onset of any epidemic in the UK by about five days. “Only a month of additional preparation time for the NHS would be meaningful.” The committee considers imposing restrictions on travel into the UK.

6 February – Sage extends self-isolation guidance6 February – Sage extends self-isolation guidance
The virus is in the UK and Sage notes that a third person, a man who had recently visited Singapore, had tested positive for coronavirus. It now advises that those who have travelled from Thailand, Japan, Republic of Korea, Hong Kong, Taiwan, Singapore, Malaysia or Macau and are showing symptoms self-isolate.The virus is in the UK and Sage notes that a third person, a man who had recently visited Singapore, had tested positive for coronavirus.

11 February – Prediction that mass testing will end11 February – Prediction that mass testing will end
Sage predicts an eventual end for any attempt at mass testing and contact tracing, saying it is not possible for the UK to accelerate coronavirus testing capacity alongside regular flu testing. It recommendeds that Public Health England establishes a criteria for when “contact tracing is no longer worthwhile”.Sage predicts an eventual end for any attempt at mass testing and contact tracing, saying it is not possible for the UK to accelerate coronavirus testing capacity alongside regular flu testing.

18 February – PHE contact tracing limited18 February – PHE contact tracing limited
Sage concludes that “priorities would shift during a potential outbreak from containment and isolation on to delay and, finally, to case management”. It says Public Health England could cope with “five new cases a week (requiring isolation of 800 contacts),” with potential capacity to increase to 50 new cases and 8,000 contact isolations.

20 February – Social distancing could slow the spread 20 February – Physical distancing could slow the spread
Meeting hears the first evidence “of local transmission unlinked to individuals who have travelled from China, in Japan, Republic of Korea and Iran”. It is also told there is some evidence from China and Hong Kong “that social distancing measures have had some impact in limiting the outbreak”.Meeting hears the first evidence “of local transmission unlinked to individuals who have travelled from China, in Japan, Republic of Korea and Iran”.

27 February – Committee hears 500,000 deaths possible27 February – Committee hears 500,000 deaths possible
Meeting discusses the “reasonable worst case scenario” in which 80% of the UK population is infected, with a 1% fatality rate – which would mean up to 500,000 deaths, a key move towards eventual lockdown. This was modelling from Professor Neil Ferguson of Imperial College, who was at the meeting.

5 March – First mention of isolating people with Covid5 March – First mention of isolating people with Covid
The meeting concludes that there would be a need, within one to two weeks, to make symptomatic people isolate for 14 days, and then about two weeks later to consider “cocooning” older or otherwise medically vulnerable people.The meeting concludes that there would be a need, within one to two weeks, to make symptomatic people isolate for 14 days, and then about two weeks later to consider “cocooning” older or otherwise medically vulnerable people.
10 March – Transmission is under way10 March – Transmission is under way
This meeting concludes that “transmission is under way in the community” and that modelling suggests “the UK is 10-14 weeks from the epidemic peak if no mitigations are introduced”. It hears that the UK could have up to 10,000 cases already, and is about four to five weeks behind Italy. There is also, it says, a “priority” to get more antibody testing.This meeting concludes that “transmission is under way in the community” and that modelling suggests “the UK is 10-14 weeks from the epidemic peak if no mitigations are introduced”.

16 March – Sage advice changes16 March – Sage advice changes
This meeting hears of a significantly different situation: now, it says, “there is clear evidence to support additional social distancing measures be introduced as soon as possible”. The minutes add: “These additional measures will need to be accompanied by a significant increase in testing and the availability of near real-time data flows to understand their impacts.”This meeting hears of a significantly different situation: now, it says, “there is clear evidence to support additional social distancing measures be introduced as soon as possible”.

It is possible, the committee is told, that the UK could now have up to 10,000 new cases per day. Sage also speaks of the possibility of closing schools. “While Sage view remains that school closures constitutes one of the less effective single measure to reduce the peak epidemic, it may nevertheless become necessary … to push demand for critical care below NHS capacity.”It is possible, the committee is told, that the UK could now have up to 10,000 new cases per day.

18 March – Evidence backs schools closures18 March – Evidence backs schools closures
This meeting is told that “available evidence now supports implementing school closures on a national level as soon as practicable to prevent NHS intensive care capacity being exceeded”. The UK now seems to be two to four weeks behind Italy. It considers measures just for London, such as closing restaurants and bars, saying the capital appears to be one or two weeks ahead of the rest of the UK.This meeting is told that “available evidence now supports implementing school closures on a national level as soon as practicable to prevent NHS intensive care capacity being exceeded”.

26 March – “No hasty decisions” on treatments 26 March – ‘No hasty decisions’ on treatments
The meeting agrees that, once R is below 1 and demand on critical care is brought within capacity, a focus is needed on behavioural and social interventions and on the testing regime necessary for exiting lockdown. The scientists advise that no hasty decisions should be made on treatments, such as the malaria drug chloroquine, based on insufficient or conflicting data. The meeting hears that nosocomial transmission – the spread of Covid-19 in hospitals – needs urgent attention. Advisers re-emphasise “the importance of urgently ramping up testing of appropriate quality”.The meeting agrees that, once R is below 1 and demand on critical care is brought within capacity, a focus is needed on behavioural and social interventions and on the testing regime necessary for exiting lockdown.

7 April – Face masks have “minimal effect” 7 April – Face masks have ‘minimal effect’
The meeting hears that the increased use of face masks would probably have minimal effect in terms of preventing the spread of infection. However, questions are raised about whether this conclusion would change if it were known that there were high levels of transmission between asymptomatic individuals.The meeting hears that the increased use of face masks would probably have minimal effect in terms of preventing the spread of infection.

However, the spread of infection within hospitals is making up an increasing proportion of cases and care homes are also flagged as a concern, with Sage noting the lack of data available. The scientists discuss the extensive pros and cons of recommending face masks, but conclude that “evidence does not currently support [their] use” in the general population.However, the spread of infection within hospitals is making up an increasing proportion of cases and care homes are also flagged as a concern, with Sage noting the lack of data available.

21 April – Obesity is a risk21 April – Obesity is a risk
The scientists decide there is “enough evidence to support recommendation of community use of cloth face masks, for short periods in enclosed spaces, where social distancing is not possible.” They add that any policy decision on masks “must not jeopardise supply” to health and social care settings. Discussions about who is most vulnerable to the disease flags up that “there is a clear signal that obesity is a risk factor”.The scientists decide there is “enough evidence to support recommendation of community use of cloth face masks, for short periods in enclosed spaces, where social distancing is not possible.” They add that any policy decision on masks “must not jeopardise supply” to health and social care settings.
