Public health campaigns and school closures were among the most effective ways to control the spread of Covid-19, according to a German research institute.
Together those measures reduced the reproduction rate, the average number of people one person with the virus goes on to infect, known as the R-value, by 0.35 and 0.24, respectively, said the Kiel Institute for the World Economy.
But just because a strategy works does not necessarily mean it should be recommended, the study's authors said, as school closures in particular resulted in other harms.
“The high effectiveness of a measure does not automatically translate into a recommendation for political implementation if it has, as in the case of school closures, strong negative effects,” said Alexander Sandkamp of the Kiel Institute.
He teamed up with Anthonin Levelu of Paris Dauphine University to analyse 14 “non-pharmaceutical interventions” and their association with the R-value in 182 countries in 2020, using statistical methods, to produce a Kiel working paper: “A lockdown a day keeps the doctor away: The effectiveness of non-pharmaceutical interventions during the Covid-19 pandemic”.
Other effective measures to reduce the reproduction rate, or R-value, of the virus included Covid-19 testing (-0.23), contact tracing (-0.15), and international travel restrictions (-0.14).
The cancellation of public events, remote working, and introducing a cap on the maximum number of people who can mingle also lowered the R-value.
Masks did not “produce statistically measurable success in the first wave” but were more effective in the second.
Local travel restrictions had “no measurable effect on infection control,” said the study authors.
“However, the decision on which measures to implement [first] also depends on their economic and social impacts,” said Mr Sandkamp, who does research on international trade at the Kiel Institute.
“Measures that are effective while causing relatively few distortions should be implemented first, such as information campaigns, testing, contact tracking, and mask wearing.”
Education disrupted by school closures
School closures were widely implemented across the world as Covid-19 spread in 2020.
According to research by Save the Children, in the following year children globally lost more than a third of the typical 190-day school year because of the coronavirus pandemic.
And during the peak of the pandemic in 2020, 91 per cent of the world's learners were locked out of schools, according to a review by Save the Children of Unesco's research.
Studies found the closures had an adverse impact on children’s mental and physical health, with long-term consequences.
Research led by Great Ormond Street Institute of Child Health in London examined 36 studies in 11 countries around the world, involving about 80,000 children and 18,000 parents, to assess the impact of lockdowns and school closures.
They found increased levels of anxiety and depression among young people.
“There was consistency in findings across studies, particularly for mental health, with almost all studies documenting poorer mental health and well-being,” the researchers said.

Dr Amal Khalid Alias revealed a recent case of a woman with daughters, who specifically wanted a boy.
A semen analysis of the father showed abnormal sperm so the couple required IVF.
Out of 21 eggs collected, six were unused leaving 15 suitable for IVF.
A specific procedure was used, called intracytoplasmic sperm injection where a single sperm cell is inserted into the egg.
On day three of the process, 14 embryos were biopsied for gender selection.
The next day, a pre-implantation genetic report revealed four normal male embryos, three female and seven abnormal samples.
Day five of the treatment saw two male embryos transferred to the patient.
The woman recorded a positive pregnancy test two weeks later.
Pox that threatens the Middle East's native species
Camelpox
Caused by a virus related to the one that causes human smallpox, camelpox typically causes fever, swelling of lymph nodes and skin lesions in camels aged over three, but the animal usually recovers after a month or so. Younger animals may develop a more acute form that causes internal lesions and diarrhoea, and is often fatal, especially when secondary infections result. It is found across the Middle East as well as in parts of Asia, Africa, Russia and India.
Falconpox
Falconpox can cause a variety of types of lesions, which can affect, for example, the eyelids, feet and the areas above and below the beak. It is a problem among captive falcons and is one of many types of avian pox or avipox diseases that together affect dozens of bird species across the world. Among the other forms are pigeonpox, turkeypox, starlingpox and canarypox. Avipox viruses are spread by mosquitoes and direct bird-to-bird contact.
Houbarapox
Houbarapox is, like falconpox, one of the many forms of avipox diseases. It exists in various forms, with a type that causes skin lesions being least likely to result in death. Other forms cause more severe lesions, including internal lesions, and are more likely to kill the bird, often because secondary infections develop. This summer the CVRL reported an outbreak of pox in houbaras after rains in spring led to an increase in mosquito numbers.

Conflict, drought, famine
Estimates of the number of deaths caused by the famine range from 400,000 to 1 million, according to a document prepared for the UK House of Lords in 2024.
It has been claimed that the policies of the Ethiopian government, which took control after deposing Emperor Haile Selassie in a military-led revolution in 1974, contributed to the scale of the famine.
Dr Miriam Bradley, senior lecturer in humanitarian studies at the University of Manchester, has argued that, by the early 1980s, “several government policies combined to cause, rather than prevent, a famine which lasted from 1983 to 1985. Mengistu’s government imposed Stalinist-model agricultural policies involving forced collectivisation and villagisation [relocation of communities into planned villages].
The West became aware of the catastrophe through a series of BBC News reports by journalist Michael Buerk in October 1984 describing a “biblical famine” and containing graphic images of thousands of people, including children, facing starvation.
Band Aid
Bob Geldof, singer with the Irish rock group The Boomtown Rats, formed Band Aid in response to the horrific images shown in the news broadcasts.
With Midge Ure of the band Ultravox, he wrote the hit charity single Do They Know it’s Christmas in December 1984, featuring a string of high-profile musicians.
Following the single’s success, the idea to stage a rock concert evolved.
Live Aid was a series of simultaneous concerts that took place at Wembley Stadium in London, John F Kennedy Stadium in Philadelphia, the US, and at various other venues across the world.
The combined event was broadcast to an estimated worldwide audience of 1.5 billion.
Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.
Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.
“Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.
Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.
“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.
Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.
From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.
Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.
BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.
Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.
Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.
“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.
Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.
“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.
“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”
The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”

Who are the Sacklers?
The Sackler family is a transatlantic dynasty that owns Purdue Pharma, which manufactures and markets OxyContin, one of the drugs at the centre of America's opioids crisis. The family is well known for their generous philanthropy towards the world's top cultural institutions, including Guggenheim Museum, the National Portrait Gallery, Tate in Britain, Yale University and the Serpentine Gallery, to name a few. Two branches of the family control Purdue Pharma.
Isaac Sackler and Sophie Greenberg were Jewish immigrants who arrived in New York before the First World War. They had three sons. The first, Arthur, died before OxyContin was invented. The second, Mortimer, who died aged 93 in 2010, was a former chief executive of Purdue Pharma. The third, Raymond, died aged 97 in 2017 and was also a former chief executive of Purdue Pharma.
It was Arthur, a psychiatrist and pharmaceutical marketeer, who started the family business dynasty. He and his brothers bought a small company called Purdue Frederick; among their first products were laxatives and prescription earwax remover.
Arthur's branch of the family has not been involved in Purdue for many years and his daughter, Elizabeth, has spoken out against it, saying the company's role in America's drugs crisis is "morally abhorrent".
The lawsuits that were brought by the attorneys general of New York and Massachussetts named eight Sacklers. This includes Kathe, Mortimer, Richard, Jonathan and Ilene Sackler Lefcourt, who are all the children of either Mortimer or Raymond. Then there's Theresa Sackler, who is Mortimer senior's widow; Beverly, Raymond's widow; and David Sackler, Raymond's grandson.
Members of the Sackler family are rarely seen in public.
