Fig. 1 — Kinetics of viral load in 35 COVID-19 cases. The copies of SARS like coronavirus 2 (SARS-CoV-2) RNA in nasopharyngeal swab (A), throat swab (B), sputum (C), faeces (D) and serum specimens (E) were estimated by means of real-time reverse-transcriptase polymerase chain reaction. The dashed curve draws with exponential growth model and indicates the dynamic tendency of viral load in variety body fluids. Each dot of viral load present as mean and standard deviation. Purple symbols denote severe cases, and cyan symbols denote mild cases.
