Table 3.

Prevalence of HEV and pAdV in pig’s blood in relation to the size of the farm breeding the animals

Farm size	No. of farms	No. of pooled blood samples*	No. of positive samples
			HEV (%; CI 95%)	pAdV (%; CI 95%)
Small	21	21	0 (0; CI 0–16.1)	4 (19.0; CI 5.4–41.9)
Medium	7	14	0 (0; CI 0–23.1)	2 (14.3; CI 1.7–42.8)
Large	37	111	5 (4.5; CI 1.4–10.2)	13 (11.7; CI 6.3–19.2)
Total		146	5 (3.4; CI 1.1–7.8)	19 (13.0; CI 8.0–19.5)

*Each small-scale farm was represented by one pooled blood sample (each pooled sample consisted of blood taken from 10 pigs), the medium-scale and large-scale size farms were represented by two and three samples respectively
