Covid-19 can put the human teams on our farms at risk.
Farm biosecurity is key to preventing the entrance of new pathogens and preventing pig diseases. Pig diseases reduce, in general, farm profitability and this is the main reason why we want them out of our premises. But human diseases can also be devastating for farm profitability, especially when they are contagious. This is the case with SARS-CoV-2 infection in humans (Covid-19). Covid-19 can put the human teams on our farms at risk. A very interesting review was published by Van Doremalen et al on coronavirus persistence on different materials and in aerosols can help us implement measures on swine farms to reduce the human risk of infection. Based on the knowledge we have today, we can divide the measures into two types: external and internal biosecurity measures.
