Key inclusion criteria
Any person 18 years of age or older who has had 1) clinically verified COVID 19, 2) suspected of being exposed to SARS-COV-2, 3) close or casual associates of 1) or 2) and those coming into New Zealand via the quarantine and isolation facilities along with staff working at the borders or in health facilities will be invited to take part in this observational study.

Study design
Defined population
Statistical methods / analysis
Data will be entered into a dedicated database (STARLIMS, Abbott Informatics) throughout the conduct of the study, and extracted in a de-identified format to SPSS for statistical analysis. Levels of biomarkers and clinical indices will be assessed for normal distribution and, if appropriate, log-transformed to validate parametric analyses including t-tests. P<0.05 will be accepted as indicating significance.

Brief summary
We will recruit up to 3000 participants including ideally 200-300 clinically proven COVID cases to assess 1) Antibody prevalence, performance and responses 2) active T-cell prevalence, responses and types 3) cardiac outcomes over the next 3 years in proven COVID cases versus “others”. Event rates will be obtained through Ministry of Health, GP, DHB, Birth Death & Marriages and phone or email follow up with participants. This will provide a biobank to draw upon for future investigator inspired work.
