The UK must prepare now for a potential new wave of coronavirus infections this winter that could be more serious than the first, says a new Academy of Medical Sciences report that included expert input from iii scientists.

The Centre for Virus Research's Dr Pablo Murcia and Dr Janet Scott were part of an advisory group of 37 experts who were rapidly assembled to create the report following a request by the Government’s Chief Scientific Advisor.

The Preparing for a challenging winter 2020/21 report stresses that ‘intense preparation’ is urgently needed throughout the rest of July and August to reduce the risk of the health service being overwhelmed and to save lives this winter.

Research suggests that COVID-19 is more likely to spread in winter with people spending more time indoors and the virus able to survive longer in colder, darker winter conditions.

Combined with the disruption already created in the health service by COVID-19, a backlog of patients needing NHS assessment and treatment, and the possibility of a flu epidemic, this poses a serious risk to health in the UK.

These new pressures are in addition to the challenge winter usually presents to the NHS, when other infectious diseases are more common and conditions such as asthma, heart attack, chronic obstructive pulmonary disease and stroke tend to worsen.  

The report notes there is a high degree of uncertainty about how the COVID-19 epidemic will evolve in the UK over the coming months but suggests a ‘reasonable worst-case scenario’ to prepare for is one where the average number of people that one infected person will pass the virus on to (Rt value) rises to 1.7 from September 2020 onwards.

Modelling of this scenario suggests there would be a peak in hospital admissions and deaths in January and February 2021 similar to or worse than the first wave in spring 2020, coinciding with a period of peak demand on the NHS.

It estimates the number of COVID-19-related hospital deaths (excluding care homes) between September 2020 and June 2021 could be as high as 119,900.

However, these figures do not take account of the fact that Government would act to reduce the transmission rate, or the recent results from a trial to treat patients in intensive care with the steroid dexamethasone, which could reduce death rates.
