First of all, it should be clarified that porcine coronavirus is a different disease from human coronaviruses. To date, there is no evidence that COVID-19 has been found in pigs or that porcine coronavirus can be transmitted to humans.
Coronaviruses affect pigs causing different diseases such as: Hemagglutinating Encephalomyelitis Virus, Epidemic Swine Diarrhea, Porcine Respiratory Coronavirus, Deltacoronavirus and Transmissible Gastroenteritis.
There are three porcine coronaviruses that are related to digestive disorders (TSG, DEP and PDCoV). On the other hand, the porcine respiratory coronavirus (PRCV) is related to respiratory problems, while the EHV virus presents two different symptoms: a more severe vomiting disease and encephalomyelitis.
Each of these variants of the swine virus represents symptoms and treatments of different characteristics, although many of them have prevention and control measures that must be taken into account to avoid them.
