Many Children Suffering Ongoing Covid Symptoms
Led by the University of Otago, and published in the International Journal of Paediatrics and Child Health, the study surveyed more than 4200 children and young adults aged three to 20 years between November 2022 and April 2023, after the first widespread Covid-19 community transmission in early 2022.
More than 70 percent of participants had a confirmed Covid-19 infection.
A quarter had suffered more frequent coughs, colds and stomach bugs since infection, while one in five reported ongoing symptoms, such as headaches (21.7 percent), fatigue (20.6 percent), stomach aches (14.6 percent) and new anxiety (13.1 percent).
Before Covid-19's widespread arrival, 82.6 percent of children rated their health as "very good" or "excellent" - that number dropped to 66.9 percent after the Omicron variant waves. Children who had Covid-19 were significantly more likely to rate their health as "fair" or "poor", compared to those who did not.
Children with pre-existing conditions, like asthma or ADHD, were more likely to develop post-Covid symptoms, but many previously healthy kids also reported new difficulties, ranging from persistent coughs to concentration problems.
Associate Professor Julie Bennett, from the university's Department of Public Health, said long-term symptoms could affect children's ability to participate in daily activities and attend school.
"Reducing infections to key to preventing Long Covid," she said. "Simple steps like opening windows to improve ventilation in classrooms, workplaces and at home helps reduce the spread of Covid-19 to others."
Bennett said common symptoms reported in New Zealand children included headaches, fatigue, stomach aches, anxiety, and more frequent coughs and colds.
"If a child has Covid, ensure they are able to rest during and after infection to prevent post-viral complications, such as Long Covid."
Co-author Larisa Hockey, of Long Covid Kids New Zealand, said the findings showed Covid-19 had had a "measurable and ongoing impact" on the health of many children.
Both previously healthy children and those with existing health conditions had reported new symptoms that affected school attendance, concentration and overall wellbeing, she added.
"There is strong evidence that preventing infection is key to preventing Long Covid. Children deserve every opportunity to grow up healthy and thrive, and that includes protecting them from preventable long-term illness.
"Long Covid is having a significant impact on children's lives and those of family members."

Leader nuclear ‘red button' concerns
PHOTO: GETTY IMAGES When it comes to those who have the power to push "the big red button" and start a nuclear war, it has always been hoped that cool heads will prevail. But a University of Otago study shows there is growing concern about the leaders of nuclear-armed nations around the world, and how their health may be affecting their decision-making. Menachem Begin. The Doomsday Clock now sits at 89 seconds to midnight — the closest it has been to catastrophe since the Cuban Missile Crisis in 1962, when the United States and Russia were brought to the brink of nuclear war. The closer it moves to midnight, the closer humanity is to the end of the world. University of Otago (Wellington) public health researcher Prof Nick Wilson said the world was again perilously close to the edge and, given that many former leaders of the world's nine nuclear-armed nations were impaired by health conditions while in office, there were concerns about their decision-making abilities while they had access to nuclear weapon launch codes. Richard Nixon. Prof Wilson, fellow researcher Associate Prof George Thomson and independent researcher Dr Matt Boyd found many of the leaders had multiple serious health issues while in office, including dementia, personality disorders, depression and drug and alcohol abuse. Their study analysed the health information of 51 deceased leaders of China, France, India, Israel, North Korea, Pakistan, Russia, the United Kingdom and the United States. Prof Wilson said 15 leaders had confirmed or possible health issues which impaired their performance and likely hastened their departure. John F. Kennedy. In one case, Israeli Prime Minister Menachem Begin had severe depression and spent his last year as leader isolated in his home. "Impairment during crises was also seen in the case of Richard Nixon's bouts of heavy drinking, including during a nuclear crisis involving the Middle East." He said there were also cases where health information about leaders had been kept secret, including United States President John F. Kennedy, whose aides concealed that he had Addison's disease; and Ronald Reagan, whose administration hid the extent of his injuries after he was shot in 1981, and the likely signs of his dementia near the end of his term. Francois Mitterrand. Prof Wilson said Mr Kennedy's performance was likely impaired by Addison's disease, back pain and his use of anabolic steroids and amphetamines in 1961 when he authorised the failed CIA-backed Bay of Pigs invasion of Cuba. In turn, Soviet leader Nikita Khrushchev's poor mental health probably contributed to him triggering both the Berlin Crisis and the Cuban Missile Crisis. And long-serving French President Francois Mitterrand clung to power until the end of his term in 1995, despite having advanced prostate cancer and his doctor concluding in late 1994 that he was no longer capable of carrying out his duties. A study of members of the British parliament also found they were 34% more likely to experience mental health problems than other high-income earners due to the stress of the job. Nikita Khrushchev. Following the rise in international instability caused by the Russian invasion of Ukraine in 2022, it had become even more important to ensure there was good leadership and governance in those countries with nuclear weapons, Prof Wilson said. "This is particularly the case for the United States, where a leader can in principle authorise the release of nuclear weapons on their own — a situation referred to as a 'nuclear monarchy'." He said there was a range of measures which could reduce global security risks from leaders whose judgement was in question. Ronald Reagan. They included removing nuclear weapons from "high alert" status, adopting "no first use" policies where nations only used nuclear weapons in retaliation, ensuring any weapon launches needed authorisation by multiple people and progressing nuclear disarmament treaties. Requirements for medical and psychological assessments could be introduced for leaders before and during their terms, and democracies could also consider introducing term limits for their leaders, as well as recall systems, so voters could petition for politicians to step down, he said.

Counting the true toll of the Covid-19 pandemic in New Zealand
As the Royal Commission of Inquiry into New Zealand's Covid-19 response continues, modelling expert Michael Plank presents a new study on the country's excess mortality rate. How many people died because of the Covid-19 pandemic in New Zealand? It sounds like a simple question, but the answer depends on more than just counting reported Covid-19 deaths. My colleagues and I recently published a study in the International Journal of Epidemiology looking at excess mortality – the number of deaths above what we would have expected if there hadn't been a pandemic. Excess mortality helps us to measure the overall impact of the pandemic, not just from Covid-19 itself but also from things like delayed medical care or the side effects of lockdowns. And because it's based on the total number of deaths from any cause, it doesn't depend on how the cause of death was determined, nor whether the death was recorded as being due to Covid-19 or not. Many people will have seen the Our World in Data Covid-19 dashboard, which allows users to compare excess mortality between countries. This dashboard shows that New Zealand's total excess mortality up to the end of 2023 was less than 1%. In other words, the number of deaths during the pandemic was less than 1% higher than expected. But not everyone agrees with this conclusion. A 2024 study by John Gibson argued that the excess mortality in New Zealand was actually much higher than this. Our World in Data's method missed a crucial factor: New Zealand's population growth ground to a halt in 2020 due to pandemic travel restrictions. With fewer people in the country, Gibson claimed, we should have expected fewer deaths; so the excess mortality was actually higher. We wanted to know if this was really true. Could the Our World in Data dashboard be inadvertently hiding a swathe of excess deaths in New Zealand? To answer this question, we built a statistical model that estimated trends in the death rate in different age groups over time. We then used this model to calculate how many deaths would have been expected if the pandemic had never happened and pre-pandemic trends had simply continued. Our model accounts for changes in population size and ageing to ensure a fair comparison. We looked at excess mortality up to the end of 2023 because we wanted to include the period after New Zealand's elimination strategy ended and the virus became widespread. Was New Zealand's pandemic death toll higher than reported? The answer from our work is a resounding 'no'. We estimated the total number of deaths between 2020 and 2023 was somewhere between 2% higher than expected and 0.8% lower. In other words, we can't be confident that more people died during the pandemic than would have died anyway. We can be confident that the number of deaths was no more than 2% higher than expected. In 2020, the number of deaths was unusually low, mainly because border closures and lockdowns inadvertently wiped out influenza as well as Covid-19. In 2022 and 2023, deaths increased as Covid-19 became widespread. The timing of excess deaths matched very closely with reported Covid-19 deaths, with the highest death rates occurring during the biggest Covid-19 waves of 2022. This suggests that the virus itself was the main driver, rather than indirect factors. Overall, New Zealand's estimated excess mortality of less than 2% is far lower than that in countries like the United Kingdom (10%) or United States (11%) over the same period. And although our study only covered the period up to the end of 2023, the overall age-standardised mortality rate in 2024 was below pre-pandemic levels. This shows that there is no mystery factor causing large numbers of unexplained deaths. Reported Covid-19 deaths appear be an accurate measure of the pandemic's death toll. So why the controversy? Gibson was right that New Zealand's population growth stalled during the pandemic. But that's only part of the story. Most deaths happen in older people, and this part of the population continued to grow during the pandemic. So, even though total population growth slowed, the number of elderly people – the group at highest risk of dying – still increased as expected. In other words, New Zealand's ageing population was a more important driver of the expected number of deaths than the number of immigrants, who tend to be relatively young. Why does this matter? The next pandemic is a question of when, not if. If we are to respond better to future pandemics, it's essential that we understand the full impact of our response to Covid-19. Some critics argue that New Zealand's elimination strategy just delayed the inevitable. Deaths that were prevented in 2020 and 2021 – the argument goes – were simply delayed until 2022 or 2023, when the virus became widespread. But the data tell a different story. Our response bought time for people to get vaccinated before they were exposed to the virus. And that massively reduced the fatality risk. New Zealand's response was far from perfect, and there were undoubtedly harms as a result of lockdowns and other measures that are not reflected in mortality statistics. But there can be no doubt that the response saved thousands of lives compared with the alternatives. Michael Plank led a group of researchers who were commissioned by the New Zealand government to provide modelling in support of the response to Covid-19 between 2020 and 2023.

After a drawn-out battle, triumph beckons
The United Kingdom finds itself, once again, in the uncomfortably sweaty embrace of a heatwave. Edinburgh, a city built for haar, drizzle and existential melancholy, now shimmers with the heat. The grey stones of Leith have acquired a new hue in the golden sunshine. Pale Edinburgers have shed their woolly layers and have emerged, blinking, into the sunlight. I have no doubt the Meadows is currently a patchwork of charred sausages and sunburned students lazing out on the grass. Alas, I do not have the time to ascertain this myself. Instead of frolicking by the seaside or lying stretched out under a tree in Pilrig Park, I am trapped inside the cool quiet of my room, hunched over my desk, typing away furiously on my battered laptop. I am not deranged; I am a university student once again, making a final attempt to finish off a master's thesis I abandoned four years ago. Four years ago I was desperately depressed, anxiety-ridden, and seriously ill with ME/CFS and Long Covid. I was in the final stretch of my second master's degree — this one in global and imperial history — at the University of Oxford. The expectation was clear: to produce a well-researched and original thesis of 15,000 words. I was decidedly not capable of this. I was barely capable of showering or feeding myself. I was, of course, not merely a victim of my circumstances. I certainly could have been a better student; I could have applied myself more, drunk less, spent more time in the library instead of bars. But my father had just suffered his first heart attack — the second would end his life, two years later — and I was far from home, unable to return to New Zealand because of brutal Covid-19 border restrictions. Add to this my family's Luddite tendencies (I went several days without receiving news of my dad's health status), and you can perhaps understand why I wasn't best placed to meet the demands of an Oxford thesis. I can understand why some readers might view my struggles at Oxford as indulgent, ungrateful or pedantic. After all, I was awarded the immense privilege of a Rhodes Scholarship, an opportunity sought after by many but afforded to few. I am deeply aware of how fortunate I am. I could never have afforded to study overseas, let alone at a university as prestigious as Oxford. But those who are quick to judge often overlook — or choose not to understand — that gratitude and suffering can coexist. I have struggled with chronic depression for the better part of my life. When I arrived in Oxford, I was also grappling with CPTSD following the death of my brother by suicide only a few years earlier. I was also physically unwell with ME/CFS, battling thick, weighty fatigue. I could barely stay awake in lectures, and my brain fog made it nigh-impossible to form coherent sentences, let alone write postgraduate essays. My gratitude for the opportunity was — and still is — genuine, but it doesn't negate the deep and debilitating reality I was living through. After withdrawing from my studies, I felt a complex mix of relief, confusion and freedom. Most of all, I felt like an abject failure. Up until that point, my sense of self-worth had been almost entirely dictated by my academic and professional successes. And yet here I was, giving up on my Oxford dreams. I was a flop, a Rhodes Scholar with nothing to show for it but a glut of doctor's notes, joint pain and an unfinished thesis. In the intervening years I returned to working on the "other side" of academia, in administration, event-planning and communications. I rediscovered how much I enjoyed science communications. Translating complex research into accessible language, telling the human stories behind the data, and building bridges between disciplines has felt like a fresh alternative to the solitary grind of academia. At times it's been somewhat awkward, having to explain my incomplete degree and the gaps in my CV. But I've also learned to be a bit kinder to myself. I have learned that rest is not laziness, that asking for help is not a sign of weakness, and that my resumé does not determine my self-worth. I'm 30 now, and I've finally learned that I cannot bully my mind or body into health. But now, to quote the immortal words of The Human League, I'm coming back — back to my studies, back to Oxford, back to that dratted thesis that has haunted me for so many years. The University of Oxford, Rhodes House, and my wonderful college (Trinity) have graciously allowed me to return to my studies, and for this, I am deeply grateful. In a nutshell, my thesis is an intellectual history of Sir Frederic Truby King (1858-1938). King, a prominent New Zealand doctor, mental health reformer, and public health campaigner, is primarily remembered for his pioneering work in infant and maternal welfare with the Plunket Society. I am exploring King's life and legacy, focusing on his time as medical superintendent at Seacliff Asylum, where he developed ideas about moral treatment, environmental determinism and discipline in mental healthcare. In 2019, I wrote a column mildly questioning the sainthood of Captain Cook, arguing (hardly originally, I might add) that his voyages, whilst remarkable, also helped lay the foundations of a violent colonial order. A few days later, Emeritus Professor Erik Olssen published a rebuttal, dismissing my claims as "specious" and suggesting that I would surely fail my studies at Oxford. (Spoiler: I did drop out shortly after — but not, alas, for the reasons he thought.) The funniest thing about returning to my studies is that I am now poring over Olssen's (admittedly excellent) work on Truby King and the Plunket Society. The irony isn't lost on me. Academia has a long memory, but it also circles back in strange ways. The professor who once prophesied my failure now resides in my footnotes. The best thing about returning to my academic studies however has been the support of my supervisor. It is a somewhat revelatory experience to realise that a supervisor can actually be a wonderful mentor. My supervisor is not only brilliant but also kind, offering generous, thoughtful feedback and taking my disability support needs seriously. I'm now only two weeks away from my submission date, and the pressure is weighing on me once again. But I feel (relatively) calm and steady. I know that just pressing "submit" will be a personal triumph, even if I receive an abysmal grade. Just having got it done will be enough. Now, if you'll excuse me, I have some footnotes to tidy up, and then I might go for a walk in the park. — Jean Balchin is an ODT columnist who has started a new life in Edinburgh.
