Brief summary

This study aims to understand how Long-COVID affects adults in Australia over time. Participants will be followed for up to 36 months after COVID-19 infection to assess changes in symptoms, functional ability, quality of life, social and broader psychosocial, behavioural and financial impacts using validated tools. The study will also examine factors associated with persistent symptoms and recovery. The findings will contribute to improved understanding of Long-COVID trajectories and may inform policy, clinical guidelines, and the development of care models for Long-COVID.

Interventions

Participants in this study will not undergo any laboratory tests, physical assessments or treatment. Participants will be recruited through three sites: RMIT University, Northern Health (primarily Victorian Virtual Emergency Department), and Hands on Health Australia.

Participants in this study will not undergo any laboratory tests, physical assessments or treatment. Participants will be recruited through three sites: RMIT University, Northern Health (primarily Victorian Virtual Emergency Department), and Hands on Health Australia. Participation involves completing self-reported questionnaires, with researchers contacting participants by phone for an initial discussion to explain the study and obtain consent. Where participants provide consent, data may also be linked to national datasets, including the Medicare Benefits Schedule, Pharmaceutical Benefits Scheme, Australian Immunisation Register and hospital datasets, via the Australian Institute of Health and Welfare. Participants will complete a set of questionnaires (online, telephone or in-person) at baseline and every three to six months for up to 36 months. Each survey takes around 30–60 minutes. Validated questionnaires include the C19-YRSm, EQ-5D-5L, F-SozU K-3 Social support scale, UCLA loneliness scale (LS) 3, MALMO POTS Score (MAPS), FACIT-Fatigue, IPAQ-SF, Mini-EAT, and SSCI-8. Throughout the study, we will also observe self-reported information on COVID-19 reinfections, hospitalisations, Emergency Department presentations, treatments received, vaccination history, social connectedness, lifestyle behaviours, functional capacity, psychological wellbeing, quality of life, relationships, employment and education impacts, healthcare utilisation, interactions with healthcare professionals, and the support participants receive or require. Participants may also provide wearable activity data where relevant. Recruitment will target individuals at three different stages following COVID-19 infection: the subacute stage (1–3 months post-COVID), the Long-COVID stage (3–12 months post-COVID), and the persistent Long-COVID stage (over 12 months post-COVID).
