‘One plausible mechanism is the reactivation of latent human herpesviruses such as HHV-6, HHV-7, and Epstein–Barr virus (EBV), which have increasingly been linked to long COVID [PASC] and ME/CFS-like phenotypes. These viruses persist lifelong in immune and neural cell populations and can reactivate under conditions of cytokine surges, oxidative stress, immune exhaustion, and mitochondrial dysfunction – the very milieu fostered by persistent [SARS-CoV-2] spike signalling.’

‘Although COVID-19 was originally considered a respiratory illness, it is now well established that SARS-CoV-2 infection can have far-reaching impacts on the nervous system. Common neurological symptoms in Long COVID [PASC] include new-onset cognitive difficulties, dysautonomia, fatigue, and peripheral neuropathy.’ from ‘Neuroimmune pathophysiology of long COVID’ by Moen et al / Psychiatry and Clinical Neurosciences (2025).

The Health and Safety Executive (HSE) has designated SARS-CoV-2, the virus that causes COVID-19, a Hazard Group 3 (HG3) pathogen that can cause severe human disease. The United Kingdom’s Health Security Agency (UKHSA) classifies SARS-CoV-2 as a notifiable organism, and COVID-19 as a notifiable disease (2026).

‘Children and adolescents face a significantly higher risk of various PASC outcomes after reinfection with SARS-CoV-2. Our paediatric findings also align with adult studies. Research in adults shows that long COVID [PASC] symptoms often worsen with repeated infections, suggesting potential shared mechanisms across age groups.’

‘The arrival of the Omicron variant marked a major shift, introducing numerous extra mutations in the spike gene compared with earlier variants. Before Omicron, natural infection provided strong and durable protection against reinfection, with minimal waning over time. However, during the Omicron era, protection was robust only for those recently infected, declining rapidly over time and diminishing within a year.’
