What treatment would you ordinarily pursue in the Delirium of Typhus, and in the severe Diarrhœa of Typhoid Fever ?

The delirium of typhus calls for treatment of systemic illness and careful nursing; severe diarrhoea in typhoid fever additionally demands replacement of losses and vigilance for intestinal injury. These are different infections, despite the similar names.

For an 1865 description of typhus, provide a quiet, ventilated room, continuous attentive nursing, fluid and nourishment, mouth care, and protection from falls or wandering. Examine for retention of urine, constipation, chest complications and exhaustion. A restless sleepless patient was sometimes given a cautiously selected opium preparation; wine or other alcoholic stimulants were also employed in supposed exhaustion. Such practice was contested: contemporary observations warned that recovery after a drug did not establish that the drug had caused recovery. Sedation was especially questionable with deepening stupor or respiratory impairment. Routine depletion of an already prostrate patient was not a rational substitute for support.^[ref]

Modern epidemic typhus is caused by Rickettsia prowazekii and requires prompt doxycycline, alongside management of hypoxia, dehydration, organ dysfunction and the precipitating infection. Testing should not postpone treatment when the clinical suspicion is strong. A low-stimulation environment and observation remain useful, while historical alcohol stimulation and indiscriminate opioid sedation are not disease-specific therapy. Control of the transmitting body lice is part of preventing further infection.^[ref]

In the historical treatment of severe typhoid diarrhoea, rest, readily tolerated nourishment and measured replacement of drinks were accompanied by attempts to quiet the bowel with opium, sometimes with an astringent such as chalk or a lead-containing preparation. These aimed at reducing stool frequency; they did not eliminate the cause. An apparent reduction of stools could conceal deterioration, and intestinal pain, distension, bleeding or collapse required renewed examination. Contemporary criticism of routine opium use in febrile bowel disease shows that this was never a uniformly established cure.^[ref]

Today typhoid fever requires an effective antibiotic selected with travel history and local antimicrobial resistance in mind, then refined by bacterial culture and susceptibility results. Assess fluid balance, circulation, electrolytes and kidney function, using oral or intravenous replacement as severity requires. Gastrointestinal bleeding, increasing abdominal tenderness, guarding, distension, shock or a sudden change in condition can indicate intestinal perforation or other severe complications and need urgent hospital assessment. Historical lead preparations are toxic; suppressing diarrhoea is not a substitute for treating the infection and its complications.^[ref]
