From: Direct contact and environmental contaminations are responsible for HEV transmission in pigs
Experimental design of the transmission experiment. Inoculated and susceptible animals are represented by red circles and green triangles, respectively. Rooms 1 to 3 contained two pens housing 3 inoculated (red circles) and three susceptible contact pigs (green triangles) and were used to assess transmission by direct contact between animals as well as transmission via the environment. Rooms 4 to 6 were dedicated to the study of the transmission between animals in two adjacent pens separated by 10 cm. One negative control group was housed in room 0.
