Five years after the United Kingdom introduced its first COVID-19 lockdown, scientists are sounding alarms regarding the loss of key lessons learned during the pandemic.

The lockdown, announced by then-Prime Minister Boris Johnson on 23 March 2020, aimed to prevent NHS hospitals from being overwhelmed by a surge of COVID-19 cases.

Experts warn that there is currently no evidence suggesting that the health service is better equipped for a potential future viral outbreak.

Professor Rowland Kao from Edinburgh University remarked that NHS hospitals were already struggling before COVID-19, stating, "When the disease arrived, the NHS was simply not in a position to take any more.

And there are no signs it will be different next time." He further indicated that upcoming pandemics could potentially exacerbate existing challenges.

In addition, researchers have highlighted that the mental health repercussions of the lockdown have not been adequately addressed.

Dominic Abrams, a professor of social psychology at Kent University, noted that while the lockdown may have had some effectiveness in controlling the virus, it failed to account for essential human needs such as connection and community, leaving significant social and psychological scars.

Since the 2020 lockdown, little effort has been made to evaluate the effectiveness of pandemic measures like social distancing and mask-wearing.

Professor Paul Hunter of the University of East Anglia expressed concern about the lack of scientific consensus regarding non-pharmaceutical interventions (NPIs), stating, "We know that NPIs do reduce transmission.

But whether the benefits outweigh the harms is still far from clear."

The global ramifications of lockdown strategies were emphasized by Andrew Shepherd, director of the Chronic Poverty Advisory Network.

He pointed out that wealthier countries pressured developing nations to implement lockdowns, which often had disastrous effects.

Many low- and middle-income countries lacked the resources to mitigate the economic fallout, leading to widespread poverty, the effects of which may take years to recover from.

Dr. Michael Head of the University of Southampton acknowledged the importance of lockdowns in pandemic responses but advocated for "smarter lockdowns that are in place earlier in the outbreak to better reduce transmission and therefore shorter in length."

The anniversary of the lockdown is also marked by the advocacy group Covid-19 Bereaved Families for Justice UK, representing nearly 10,000 bereaved individuals.

They have appealed to Chancellor Rachel Reeves to reconsider proposed cuts to disability benefits, citing that rampant inequality contributed significantly to the UK's high COVID-19 death toll.

Their letter highlighted that disabled individuals were 11 times more likely to die from the virus compared to non-disabled individuals.

The group critiques perceived government neglect of the inequalities exacerbated by the pandemic, arguing that instead of addressing these issues, proposed cuts may drive more individuals into poverty and further decrease preparedness for future health crises.

They warn of a phenomenon they term "Covid amnesia," suggesting that past lessons critical to addressing health service funding are at risk of being forgotten.
