Evaluation of related concentrated water samples (dam reservoir and WTP_D) for the presence of HEV RNA and infectious particles.
| Months | HEV RNA (gc/L) |
HEV Reduction (%) after Treatment | HEV Infectivity (*) | ||
|---|---|---|---|---|---|
| Dam Reservoir | WTP_D | Dam Reservoir | WTP_D | ||
| February | 29.1 | 75.2 | NR | Negative | Negative |
| April | 109,687.5 | 5,617.1 | 94.9 | Negative | Negative |
| May | 2,412 | 0 | 100 | Negative | Negative |
| June | 0 | 58.7 | NR | Positive | Positive |
*Based on RT-qPCR results, when RNA extracted from putative viruses produced in Vero E6 cultures were identified as HEV RNA; NR—no reduction with treatment; gc/L: genomic copies per liter of sampled water, calculated with RT-qPCR results (average values of two independent reactions) and data from Table 1.
