Definition: The word "anticontagion" in the Bible means not spreading disease through contact with a sick person, which is often used to describe avoiding infection. It was first mentioned in Isaiah 13:9-10 where it means you can't spread disease by coming into contact with someone who has the virus or illness. This principle was later explained in Exodus chapter 25:7 when Moses told Joshua not to bring anyone else into Egypt unless he had been tested for plague and showed signs of being ill.
