Brief summary

Long-term sequelae of COVID-19 are unknown but there is increasing evidence that some people who have recovered from COVID-19 report lasting effects of the infection or have had the usual symptoms for far longer than would be expected, namely ‘Long COVID’. Our aim is to get a better understanding of how COVID-19 impacts both physical and mental health in the long run. This will be done via blood tests and questionnaires to identify any abnormalities. Potential participants are eligible if they have had a laboratory confirmed diagnosis of COVID-19, 12 – 17 months ago, are over 18 years old and have been under the care of Regional Public Health during the initial illness. Once informed consent is obtained, participants will complete 8 questionnaires online and provide a blood sample at their local blood collection centre. Additional informed consent will be sought if a participant agrees to provide a blood sample to be stored for future unspecified research. All informed consent processes will be done remotely. The entire study will be done remotely, except for blood sampling which will be done at a local collection centre. Once a participant has completed the questionnaire and given a blood sample, an investigator will be in touch with them with the results via telephone. The investigator will also send out a link via email to the Participant Satisfaction Survey at the end of the phone call. This will be a descriptive analysis of the feasibility of conducting a study remotely, purely for internal use at MRINZ.

Interventions

Participants will be adults aged 18 and over with a laboratory diagnosis of COVID-19 notified to Regional Public Health in the preceding 12-18 months. Participants will undertake 8 online questionnaires sent via email about physical and mental health (approx 20-25 minutes). They will also be requested to provide a blood sample at their local blood collection centre. Optional consent will be sought to store a single blood sample for future unspecified use for up to 24 months after study completio

They will also be requested to provide a blood sample at their local blood collection centre. Optional consent will be sought to store a single blood sample for future unspecified use for up to 24 months after study completion. Several blood samples will be taken for the main study which will be analysed and destroyed. If the participants consents to taking part in the optional study, an extra single blood sample will be taken for storage for future unspecified use. The questionnaires and blood samples will be done once at at a single timepoint between 12-18 months post onset of acute COVID-19 infection.
