| Mild (n = 1 a) | Moderate (n = 14) | Severe (n = 11) | |
|---|---|---|---|
| Demographics | |||
| Age, years a | 23 | 21–23 | 21–23 |
| Hospital stay, days a | 5 | 9–11 | 11–15 |
| Actual treatment, days a | 4 | 10–12 | 13–17 |
| ICU treatment, days a | 2 | 2–4 | 3–5 |
| Laboratory tests | |||
| Anti-HTNV IgM positivity | 0 | 4 (29%) | 1 (9%) |
| Anti-HTNV IgG positivity, titers b | 0 | 12 (86%), 1:3904 ± 1598 | 9 (82%), 1:1844 ± 1458 |

Abbreviations: ICU = intensive care unit. IgG = immunoglobulin G. IgM = immunoglobulin M. RT-PCR = reverse transcription-polymerase chain reaction. a ROKA15-5, one of the mild patients, was negative for both anti-HTNV IgG and RT-PCR at the initial phase (collection date: 25 December 2015). Then, the patient was diagnosed with HTNV infection by RT-PCR at the diuretic phase (collection date: 26 December 2015). b Each parameter is presented as the mean ± standard deviation.
