Table 3. Prevalence and infection intensity as determined in the field by zoospore filtering method.
| Locality | Positive/Total | Prevalence (%) | Infection intensity (ZGE1 ± SD) |
| Chuncheon | 3/16 | 18.8 | 66.23±21.682 |
| Hwacheon | 3/16 | 18.8 | 49.63±14.86 |
| Yanggu A | 3/14 | 21.4 | 66.90±37.00 |
| Yanggu B | 4/18 | 22.2 | 45.22±15.12 |
| Pocheon | 8/28 | 28.6 | 80.20±51.67 |
As a comparison, a previous study on Korean amphibians by swabbing found a mean prevalence of 16.7% [29].
