It was supposed to be a post-Covid-19 summer in Europe. Masks are gone in most places, and vacation season is in full swing as workers rush for the beaches and cities they missed in the two years marked by the pandemic. But instead, the reality confronting people is that the virus never went away.

A super-transmissible subvariant of the Omicron strain, known as BA.5, is fuelling a fresh increase in infections, with cases climbing across the UK and the continent. Intensive-care admissions are rising, according to the European Centre for Disease Prevention and Control, which has warned that another wave of the disease is starting.

The ending of restrictions on international travel and the return of mass-participation events such as music festivals are also helping the virus to spread. And cases may already be far higher than the figures show, given most countries have dramatically scaled back testing.

But governments have long thrown out the initial Covid playbook, and are loath to tighten mask rules, limit gatherings or reinstate vaccine and testing requirements for travel. Most are pushing for another round of boosters for at-risk people, counting on Europe’s relatively high vaccination rates to continue to keep the death rate down.

The successive waves of ever more infectious versions show that it’s still not clear what living with the virus will mean in the long run.

The timing of the uptick suggests that Covid isn’t yet seasonal like the winter flu. Instead, the successive waves of more infectious versions show that it is still not clear what living with the virus will mean in the long run, says Martin McKee, professor of European public health at the London School of Hygiene and Tropical Medicine.

“This isn’t like seasonal influenza,” he says, adding that there is no guarantee that the current vaccines will continue to be as effective against future variants. “We’re seeing waves coming every few months. And as a consequence, we need to reassess where we go with this.”

To combat the summer spike, the European Centre for Disease Prevention and Control issued new guidance last week recommending that adults over the age of 60 and medically vulnerable people of any age consider a second booster now instead of waiting for a shot that’s been adapted to be more effective against the current variants.

According to the centre’s director, Andrea Ammon, given that most people in that age group had their original boosters more than three to six months ago, protection against severe disease may be waning.

“The risk for people is now,” said Pierre Delsaux, head of HERA, the EU’s emergency health authority. “It’s better to be vaccinated now because the current vaccines are still effective.”

In the UK, the government announced Friday it will broaden its Covid booster shot campaign, set to begin in the autumn, to include everyone aged 50 and over. The infection rate there is rising, and is at the highest since April in England, according to the latest survey.

Hospital admissions are also rising, in some cases more quickly than the recorded spike in infections. The disparity between the measures is probably due to less accurate surveillance, says Louise Blair, who leads the vaccine and variants team at London-based data firm Airfinity.

She says that the summer wave is a reminder that the virus is not seasonal yet. “We’re actually seeing cases and waves being driven by new variants rather than mixing indoors,” Blair says. 

The surge is not confined to Europe. The US Centres for Disease Control and Prevention says that the BA.5 variant probably accounts for about 65% of cases. Infections there could reach 600,000 cases a day, Bloomberg Intelligence estimates in a report.

New York’s positivity rate is at the highest since January, and Los Angeles County raised its Covid warning level last week. It also warned that if case numbers are sustained, masks will be required indoors. In Japan, Tokyo lifted its infection alert to the highest level.

“From a psychological perspective, many people may feel like they are caught in a limbo around Covid,” says Rachel McCloy, a behavioural psychologist from the University of Reading. The absence of restrictions sends a message that things are back to normal, but “on the other side rates are rising, people are ill and at risk, and everything is still very much not as it was,” she says.
