Figure 4. Nasal cell composition in healthy controls, confirmed and suspected COVID-19 patients.

Figure 4.

a) Representative flow cytometry plots for cellular composition in the nasal mucosa of healthy controls, PCR-confirmed COVID-19 and PCR−/IgG+ SARI patients. b) Proportions of T cells, B cells, neutrophils and monocytes in nasal mucosa of healthy controls and COVID-19 patients. The horizontal bars represent the median and interquartile range (IQR). Data were analysed using Kruskal-Wallis test (Healthy controls, n=20; PCR confirmed COVID-19; n=20; PCR−/IgG+ SARI, n=11). SARS-CoV-2, severe acute respiratory syndrome coronavirus 2; COVID-19, coronavirus disease of 2019; PCR, polymerase chain reaction; IgG, immunoglobulin G; SARI, severe acute respiratory infection
