§ 81. Typhus contagiosus, bellicus. Hospital or jail fever.

This typhus is characterized by the symptoms of the ordinary typhus or the typhus putridus, and is propagated by a contagium. At first it is of an inflammatory character, the typhoid symptoms only setting in afterwards with tendency to exanthema, whence the fever is also termed petechial fever.

The treatment is pretty much the same as that of typhus and typhus putridus. The principal remedies in typhus petechialis are probably Bryonia, Rhus, Arsenicum.

Dietetic rules. - Every contagium being increased by excessive warmth and becoming so much more poisonous as the temperature of the sick room is kept above the proper standard-the thermometer in a sick room should never be above 67° Fahrenheit. To have this temperature in the summer season, vessels with cold water should be constantly kept in the room and the room should be frequently sprinkled. The patient should rest upon a mattress, and should be but lightly covered.

The patient must be kept clean; the room is to be frequently aired and only one patient should be in a room at a time. The contagium is increased by several patients being confined in the same room. Among the means which have been recommended for the destruction of the contagium, the best is undoubtedly a frequent renewal of air by means of a current passing through it; the patient has to be guarded against that current, of course.
