Significant return to office could see 'rapid' rise in Covid hospitalisations

It is "highly likely" that a decrease in the number of people working from home in the next couple of months would lead to a "rapid" rise in hospital admissions for Covid, scientific advisers to the government have warned.

Millions of Britons have been heading back to the office this month, coinciding with the return of schools and universities. Last week, London saw its busiest morning rush-hour since the pandemic hit, with hundreds of thousands of journeys made across the city, according to official data.

But modelling published on Tuesday by a sub-group of the Scientific Advisory Group for Emergencies (Sage) suggests there is the "potential" for another large wave of hospitalisations in the coming months.

The sub-group on pandemic modelling said there was "a clear consensus that continued high levels of homeworking have played a very important role in preventing sustained epidemic growth in recent months.

"It is highly likely that a significant decrease in homeworking in the next few months would result in a rapid increase in hospital admissions."

The group said there was "significant uncertainty" around the trajectory of the pandemic given "the scope for increased transmission after the end of the school holidays" and the questions that remain over the duration of immunity acquired through either infection or injection.

Although the UK's vaccines have weakened the link between infection and severe disease, helping to reduce hospitalisations, any significant rise in cases will still "likely" lead to an increase in admissions, the government's scientific advisers said.

Senior NHS officials have already warned that hospitalisations are rising at an "alarming" rate, leading to growing pressure on health services in the UK. Government data show that Covid bed occupancy is now at its highest level since 10 March, after daily admissions passed the 1,000 mark last week.

The modelling group said it "remains the case" that the earlier interventions are brought in, the lower prevalence is kept, reducing the direct burden of Covid-19 and reducing the risk of needing more stringent measures.

"If enacted early enough, a relatively light set of measures could be sufficient to curb sustained growth," the Sage modellers said. "During a period of sustained epidemic growth, however, the more stringent the measures introduced, the shorter the duration needed for the measures to be in place to reduce to a given prevalence."

Announcing government plans to administer booster jabs to more than 30 million Britons, Professor Jonathan Van-Tam, deputy chief medical officer for England, said the UK was on course for a "bumpy" winter due to a combination of Covid-19, rising flu cases, and the spread of other respiratory illness such as RSV (respiratory syncytial virus).

"We know that this pandemic is still active, we are not past the pandemic, we are in an active phase still," he told a Downing Street briefing.

As part of its Covid "plan B" for autumn and winter, when infections are expected to rise, the government said it will reintroduce compulsory face coverings in certain settings and ask people to work from home if the NHS falls under "unsustainable pressure".

However, the prime minister's official spokesperson said Boris Johnson had "stressed his desire to see us continue to bolster our vaccine programme as the first line of defence, supported by testing, public health advice, and a variant surveillance system".
