Homeostasis describes an equilibrium that has been achieved in a specific system. Under the assumption that the water was relatively calm beforehand, the sudden storm disrupts the specific system sending it out of equilibrium, with perhaps violent interactions above and below the water. A virus in a body or a computer system, interacts in such a way as to disrupt the homeostasis and cause the equilibrium to be disrupted, for a computer system this could be failure to boot or exposure to critical information. For a body, this obviously can set off a chain of events that disrupt the internal equilibrium that lead to physical manifestations like a fever, chills, slow or rapid heart beat, vomiting and other symptoms. Both the virus and the sudden storm create violent and/or unusual reactions within those systems, that are contrary with the concept of homeostasis.
