Cook them thoroughly. Raw seafood of any kind is a problem. Many parasites will be killed by pickling in lime juice, but I wouldn't risk that with a virus.
Most seafood has parasites. Not all can infect humans however. Its better to cook seafood. Places where eating raw fish is customary often has a high population of people with parasites. Lime juice is a traditional way of dealing with this, but I am unsure that the acid is sufficient. Heat permeates through any well cooked food. Viruses are vulnerable to heat.
