Before the attack, slight chills; headache; disturbed sleep; no appetite; cough; coryza. The attack generally begins with severe chillf followed by continued fever; patient confined to bed; heaviness and numbness in head; dizziness; flashes of light before the eyes; noises in the ears; deafness; pain in the limbs; trembling; stupor; delirium; pulse one hundred or more; temperature high; urine scanty; eruption, resembling that of measles, but not appearing on the face; thick, brown coating on the tongue.
The common name for this affection is ship-fever, which is derived from the fact that the majority of cases occurring in this country may be traced to importation through immigrants, particularly those coming from Ireland, where the disease occurs much more frequently than in this country. The symptoms of this disease are very similar to those of typhoid fever,-stupor and delirium being still more characteristic of typhus than of typhoid fever. It occurs most frequently in years of famine, when people are badly fed, and seems liable to attack persons in military camps, prisons, crowded barracks, tenement houses, and on shipboard where a large number of persons are crowded into poorly ventilated cabins. The active symptoms of the disease generally terminate quite suddenly with a profuse perspiration, after which the patient slowly recovers. The disease is very contagious.
