Thus, the infection patterns in goats (e.g., dynamics of infection, clinical outcomes, and shedding patterns) need clarification, and experimental studies using goats have improved our scientific knowledge on this topic. ...
... The viral load peaks around 4-5 days after symptoms onset at 1.8 × 10 6 copies/ml. While SARS-CoV-1 viral load, as MERS-CoV, peaked around 10 days after symptoms onset, most studies agree that SARS-CoV-2 viral load peaks sooner, around 5 days, Lescure et al. (2020) and Zou et al. (2020). Concerning antibodies, they increase sharply until week 2 then slower until a month after infection and start to decrease within 2-3 months (Long et al. 2020;Seow et al. 2020). ...
