Table 1 Summary of the infectious dynamics parameters and comparison with data from the HEV-only infection experiment [25]

From: Hepatitis E virus chronic infection of swine co-infected with Porcine Reproductive and Respiratory Syndrome Virus

  HEV + PRRSV HEV alone [25]
Latent period (days) 13.4 7.1
(8.6; 17.1) (3.2; 12.3)
Infectious period (days) 48.6 9.7
(27.9; 84.6) (8.2; 11.2)
Seroconversion period (days) 43.1 26.3
(35.7; 52.2) (23.5; 29.5)
Direct transmission (days−1) β w 0.70 0.15
(1.2.10−3; 3.67) (0.03; 0.31)
Indirect transmission (g/ge/d) β w E 6.6.10−6 2.0.10−6
(1.4.10−10; 1.3.10−4) (1.1.10−7; 7.0.10−6)
  1. β w is the direct transmission rate, defined as the mean number of newly infected pigs generated by a single infectious individual in a fully susceptible population per day. β w E represents the within-pen transmission rates related to the environmental component, defined as the mean number of newly infected pigs per HEV genome equivalent per gram of feces in the environment (see text for more details). Numbers in brackets are the upper and lower limits of the 95% credibility interval.
