Seroprevalence and evolutionary dynamics of genotype 4 hepatitis E virus in Shandong Province, China

Table 3 Hepatitis E virus loads in patient fecal samples and swine bile samples

Sample origin	Positive sample numbers and HEV loads
	RT-nPCR (+)/RT-qPCR(+)	RT-nPCR (-)/RT-qPCR (+)
Patients	12, 6.81 × 104-1.53 × 107 copies/mL	8, 6.75 × 102-1.35 × 103 copies/mL
Swine	4, 4.92 × 106-5.46 × 107 copies/mL	-

The HEV loads were detected by RT-qPCR. Only one patient sample’s HEV load was 1.53 × 10⁷ copies/mL, while the HEV loads of other samples were less than 4.92 × 10⁶ copies/mL. HEV: Hepatitis E virus.
