Kinetics of Puumala hantavirus (PUUV) -specific humoral immune response. Each patient's first available serum sample is represented by a dot. Antibody titres were significantly (p <0.05) higher in late samples then in early samples, r, r² and p-value were calculated using linear regression (log₁₀ value of the titre). Moderate/severe patient samples are marked by red squares. (No samples were collected day 10–13).
