We conducted a longitudinal study by sampling the feces and blood of piglet groups from each farm at fixed intervals during a 2-5 months period, and then we determined PEDV shedding and the antibody presence. The highest fecal PEDV RNA shedding titer was observed in 3-6 day-old piglets with mean values (among shedding animals) of 5.9, 5.6, 5.6, and 6.2 log 10 copies/mL on F1, F2, F3, and F4, respectively ( Figure 1B; Supplementary Table 3 ). Determining the viral loads and shedding rates of PEDV in real field situations during outbreaks is important in evaluating the virulence of a strain and in predicting the susceptibility of infected animals, at different ages and in the various farm units, within a herd.	./cache/cord-319460-n4ezxnjc.txt	./txt/cord-319460-n4ezxnjc.txt
