Last Christmas your friend, Steve, took a trip to Brazil to hang out at the beach and to visit the Amazon (the place not the online store!). A couple of days back in the states from his trip, he tells you he can’t come to your party because he isn’t feeling well. You ask him what is wrong, and he tells you he has a headache and muscle aches. The next day he has a high fever, chills and some nausea/vomiting. He isn’t eating much at this point.
