Public health researchers have uncovered concerning evidence that a significant number of children and young people are experiencing long-term symptoms following a Covid-19 infection. A study led by the University of Otago and published in the International Journal of Paediatrics and Child Health reveals that over 20% of children and young adults continue to suffer from symptoms such as headaches, fatigue, stomach aches, and new-onset anxiety months after infection.

The research surveyed more than 4,200 children aged three to 20 years between November 2022 and April 2023, following the first wave of community transmission in early 2022. Over 70% of the participants had confirmed cases of Covid-19, and the findings highlight a marked decline in self-reported health among children after infection. Before the pandemic, 82.6% of children rated their health as "very good" or "excellent," but this dropped to 66.9% post-omicron waves.

Children infected with the virus were significantly more likely to rate their health as "fair" or "poor" compared to those who remained uninfected. The study also found that children with pre-existing conditions such as asthma or ADHD were more prone to develop post-Covid symptoms. However, even previously healthy children reported new challenges, including persistent coughs, colds, and concentration difficulties.

Associate Professor Julie Bennett from the University of Otago's Department of Public Health emphasized the importance of reducing infections to prevent long-term complications. She noted that simple measures, such as improving classroom ventilation and ensuring rest periods for infected children, can make a significant difference. "Long-term symptoms can impact a child's ability to attend school and engage in daily activities. Preventing infection is key to preventing Long Covid," she said.

Larisa Hockey, co-author and representative of Long Covid Kids New Zealand, echoed these sentiments. She stated that the findings underscore the measurable and ongoing impact of the virus on children's health. Both healthy children and those with existing conditions have reported new symptoms affecting their school attendance, focus, and well-being. "Children deserve every opportunity to grow up healthy and thrive. Protecting them from preventable long-term illness is crucial," she added.

The study highlights the urgent need for public health strategies to mitigate the spread of the virus, especially among vulnerable populations. While vaccines and treatments have played a role in reducing severe illness, the long-term effects of the virus on children remain a pressing concern. As experts continue to monitor the situation, the focus is shifting toward prevention, early intervention, and support for those affected by Long Covid.
