"do you want to try typhus?"

 The term typhus comes from the Greek word typhos, 'hazy', which describes the stupor that is a common symptom of the disease. Epidemics of typhus occurred in many wars, including the English Civil War, the Thirty Years' War and the Napoleonic Wars. During Napoleon's retreat from Moscow typhus killed more French soldiers than the Russian army did. Other symptoms of the disease include abdominal pains, joint pains, rashes, coughs, fever, low blood pressure and nausea and vomiting. The first typhoid vaccine was invented in the interwar period of the twentieth century by a Polish biologist, Rudolf Weigl.
