  Through study completion an average of 1 year

Study Arms (5)

COVID -19 with chronic lung disease

Subjects with swab confirmed COVID-19 and underlying chronic lung disease (n=20)

Other: Blood tests sputum, nasal lavage and brushing

COVID-19 without chronic lung disease

Subjects with swab confirmed COVID-19 and no chronic lung disease (n=60) Severe (n=46) (defined by presence of ARDS, sepsis or severe pneumonia) Mild/Moderate ( n =30) (absence of severe criteria)

Other: Blood tests sputum, nasal lavage and brushing

Chronic Lung disease

Subjects with chronic lung disease (identified as requiring shielding based on severity) but no COVID-19 (n=18) Unable to recruit sufficient patients with chronic lung disease and no COVID

Other: Blood tests sputum, nasal lavage and brushing

Healthy volunteers

Healthy subjects with no COVID-19 (n= 68)

Other: Blood tests sputum, nasal lavage and brushing

Healthy volunteers with COVID and no Lung disease ( n =115)

Blood tests

Interventions

Blood tests sputum, nasal lavage and brushing OTHER

Venesection, sputum nasal lavage and brushing if appropriate

Also known as: Blood tests, Sputum, Nasal lavage, Nasal brushings, EndoPAT

Biospecimen

Retention: SAMPLES WITH DNA

Spontaneously expectorated sputum, nasal lavage, brushings and nasal synthetic absorptive matrix (SAM) samples Venous blood (60mls) will be taken into Lithium Heparin tubes and PAXgene RNA tubes PAXgene tubes will be stored at -80C for further host genetic sequencing analysis. Further immunological analysis using yeast surface display for serum antibody profiling, single B cell sorting to generate monoclonal antibodies and ELISPOT to analyse CD4 and CD8 T cell ELISPOT to SARS CoV-2 peptide pools.
