The Long-Term Impact of Covid-19 Lockdowns: Lessons from Countries That Chose Different Paths

The Global Lockdown Experience

In March 2020, the world watched in disbelief as Covid-19 swept across nations, forcing billions into their homes. The sudden confinement to four walls and computer screens was a jarring experience for many. National leaders worldwide urged citizens to stay home, venturing out only for essential supplies or daily exercise. This drastic measure aimed to curb the spread of a virus that had already claimed thousands of lives.

Tony Beckingham, a theatre worker in London, recalls cycling into the city with his partner during the early days of the lockdown. The usually bustling streets of Piccadilly Circus and Leicester Square were eerily quiet, leaving him with a profound sense of unease. "It was really upsetting – instantly," Beckingham remembers.

Countries That Chose Different Paths

While most countries imposed strict lockdowns, a handful, including Sweden, Taiwan, Uruguay, and Iceland, opted for different strategies. These nations avoided severe restrictions on movement, instead relying on measures like limiting large gatherings, extensive testing, and quarantine protocols.

Sweden: A Case Study in Voluntary Compliance

Sweden’s approach was particularly controversial. The country did not enforce a strict lockdown but relied on voluntary behavioural changes from its citizens. Anna Mc Manus, an HR administrator and blogger in Gothenburg, noted the stark contrast between Sweden and its neighbours. While countries like Norway, Finland, and Denmark imposed national lockdowns, Sweden’s strategy was more relaxed. Mc Manus recalls frequent walks and strict mask-wearing at her workplace, but also the lack of enforcement on social distancing guidelines among some citizens.

A study published in May 2024 by Ingeborg Forthun at the Norwegian Institute of Public Health compared excess deaths in Sweden, Norway, Denmark, and Finland. The findings revealed a noticeable spike in excess deaths in Sweden during the initial waves of the pandemic. However, by 2021 and 2022, the excess mortality in the other three countries rose compared to Sweden.

Economic and Social Debates

Economists have argued that Sweden’s approach was economically beneficial due to lower costs. However, the lack of a lockdown remains a contentious issue. Nele Brusselaers, a Swedish epidemiologist, criticized her country’s strategy, noting the emotional and social costs. "I’m a medical doctor so of course I care about lives," she says. "We want to save every single life."

Tanzania: A Different Story

Tanzania’s approach under former President John Magufuli was even more unconventional. The country never imposed any Covid-19 lockdowns, and Magufuli dismissed lockdowns and other public health interventions in favor of traditional herbs and later rejected vaccines. History lecturer Fadhili Mtani describes Magufuli’s approach as "unscientific." Official figures suggest around 840 people have died of Covid-19 in Tanzania, but an international collaboration estimates the actual number could be between 102,000 and 188,000.

Mtani argues that a lockdown, albeit with fewer restrictions on workers, could have been beneficial. "The majority of people are poor. To deny movement for them is to deny their existence," he explains.

The Effectiveness of Lockdowns

Many scientists emphasize that lockdowns were crucial in the early stages of the pandemic, before vaccines were available. Adam Kucharski, a professor of infectious disease epidemiology at the London School of Hygiene & Tropical Medicine, highlights the severe pressure on health services in the UK. "The NHS was overwhelmed," he says, referring to the emotional testimony of doctors who spoke to the UK’s public inquiry into the government’s Covid-19 response.

A 2021 study revealed that certain aspects of national lockdowns, such as banning gatherings of more than 10 people or closing schools and universities, were especially effective in reducing transmission. However, shutting restaurants and bars had a slightly lesser impact. Adding a strict stay-at-home order on top of such measures only had a small additional effect.

Iceland and New Zealand: Contrasting Approaches

Iceland and New Zealand offer surprising comparisons. Both are wealthy island nations with relatively small populations, but while New Zealand introduced a strict lockdown on 25 March 2020, Iceland never did. Iceland’s strategy focused on a test and trace program, monitoring infections and contacts to quarantine individuals rather than entire populations. Leah Grout, a research data analyst specializing in public health, notes that both countries fared well in terms of mortality rates and economic impacts.

Long-Term Effects and Future Preparedness

The long-term effects of lockdowns on children, education, and economies are still playing out and will likely not be fully understood for many years. Governments must have a clear plan that they communicate in advance of any new pandemic to improve public acceptance and adherence to strict mitigations.

Did You Know?

• Sweden’s Approach: Sweden’s decision to avoid a strict lockdown was based on voluntary compliance and extensive testing, but it faced criticism for high numbers of deaths at care homes.
• Tanzania’s Unconventional Strategy: Tanzania’s former president, John Magufuli, dismissed lockdowns and other public health interventions, opting for traditional herbs and rejecting vaccines.
• Iceland’s Test and Trace: Iceland’s test and trace program was effective in controlling the spread of Covid-19 without imposing a strict lockdown.

Pro Tips for Future Pandemics

• Clear Communication: Governments should communicate their plans clearly and in advance to improve public acceptance and adherence.
• Data-Driven Decisions: Use scientific studies and data to inform public health decisions, balancing the economic and social costs.
• Community Engagement: Engage with the community to ensure that public health guidelines are followed and to address any concerns or resistance.

FAQ Section

What were the main differences between Sweden’s and other countries’ lockdown strategies?

Sweden avoided strict government-imposed controls, relying mainly on voluntary behavioral changes from its citizens. Other countries, like Norway, Finland, and Denmark, imposed strict lockdowns, closing schools and most other aspects of public life.

How did Iceland manage to control Covid-19 without a strict lockdown?

Iceland introduced a test and trace program, monitoring infections and contacts to quarantine individuals rather than entire populations. This, along with some restrictions on social gatherings and border closures, helped control the spread of the virus.

What were the economic and social costs of lockdowns?

Lockdowns had significant economic and social costs, including job losses, business closures, and mental health issues. However, they were crucial in saving lives and limiting the pressure on health services in the early stages of the pandemic.

What can we learn from countries that chose different paths?

Countries that chose different paths, such as Sweden and Iceland, show that it is possible to control the spread of a pandemic without resorting to national lockdowns. However, the end results depend on the attributes of specific countries, their populations, and their healthcare systems.

How can governments better prepare for future pandemics?

Governments should have a clear plan that they communicate in advance of any new pandemic. This includes using scientific studies and data to inform public health decisions, balancing the economic and social costs, and engaging with the community to ensure that public health guidelines are followed.
