RESUMEN
AIM: To explore the prevalence of ongoing symptoms and laboratory abnormalities in confirmed cases of COVID-19 from the first wave within the Greater Wellington Region, after at least 12 months post infection. METHOD: COVID-19 cases were obtained from EpiSurv. Eligible participants electronically completed questionnaires (Overall Health Survey, Patient Health Questionnaire-9 [PHQ-9], Generalised Anxiety Disorder-7 [GAD-7], Pittsburgh Sleep Quality Index, EuroQol 5 Dimension 5 Level [EQ-5D-5L], Fatigue Severity Scale [FSS], WHO Symptom Questionnaire, Modified Medical Research Council Dyspnoea Scale [mMRC Dyspnoea Scale]). Blood samples were analysed for cardiac, endocrine, haematological, liver, antibody, and inflammatory markers. RESULTS: Forty-two of 88 eligible cases undertook the study. Participants were enrolled at a median 628.5 days from symptom onset. Fifty-two point four percent felt that their current overall health was worse than it was prior to contracting COVID-19. Ninety percent of participants reported at least two ongoing symptoms since their acute illness. Between 45-72% of participants reported each of anxiety, depression, dyspnoea, pain/discomfort, and sleep difficulties, assessed using the GAD-7, PHQ-9, mMRC Dyspnoea Scale, EQ-5D-5L and FSS questionnaires respectively. There were minimal laboratory abnormalities. CONCLUSION: There is a high prevalence of ongoing symptoms following the first wave of COVID-19 infection in Aotearoa New Zealand. At a median of 1.7 years post infection, there is a wide spectrum of symptoms and symptom severity, although as an observational, cross-sectional study a causal relationship between symptoms or their severity and COVID-19 infection cannot be firmly established.
