Transmissible gastroenteritis is a highly contagious viral illness affecting swine of all ages, marked by symptoms such as diarrhea and vomiting. The disease is triggered by the TGE virus, which belongs to the Coronaviridae family. Piglets younger than two weeks often experience high mortality rates, though the fatality rate decreases as they age.
