Transmissible Gastroenteritis Virus (TGEV) is a highly contagious virus that primarily affects pigs, particularly young piglets. It causes severe gastrointestinal disease, leading to symptoms such as vomiting, diarrhea, and dehydration. The virus spreads through direct contact with infected animals or contaminated environments, making it a significant concern for swine producers. TGEV belongs to the Coronaviridae family, which also includes other viruses like SARS-CoV and MERS-CoV. Vaccination and biosecurity measures are essential for controlling outbreaks and protecting pig populations. Early detection and management can help minimize the impact of TGEV on swine health and production.
