Overview
Typhus must be differentiated from other diseases that cause fever, rash, diarrhea and vomiting, such as Ebola, Typhoid fever, Malaria and Lassa fever.[1][2][3][4][5]
Differentiating Typhus from other Diseases
The table below summarizes the findings that differentiate Typhus from other conditions that cause fever, diarrhea and abdominal pain:
| Disease | Findings |
|---|---|
| Ebola | Presents with fever, chills vomiting, diarrhea, generalized pain or malaise, and sometimes internal and external bleeding, that follow an incubation period of 2-21 days. |
| Typhoid fever | Presents with fever, headache, rash, gastrointestinal symptoms, with lymphadenopathy, relative bradycardia, cough and leucopenia and sometimes sore throat. Blood and stool culture can confirm the presence of the causative bacteria. |
| Malaria | Presents with acute fever, headache and sometimes diarrhea (children). A blood smears must be examined for malaria parasites. The presence of parasites does not exclude a concurrent viral infection. An antimalarial should be prescribed as an empiric therapy. |
| Lassa fever | Disease onset is usually gradual, with fever, sore throat, cough, pharyngitis, and facial edema in the later stages. Inflammation and exudation of the pharynx and conjunctiva are common. |
| Yellow fever and other Flaviviridae | Present with hemorrhagic complications. Epidemiological investigation may reveal a pattern of disease transmission by an insect vector. Virus isolation and serological investigation serves to distinguish these viruses. Confirmed history of previous yellow fever vaccination will rule out yellow fever. |
| Shigellosis & other bacterial enteric infections | Presents with diarrhea, possibly bloody, accompanied by fever, nausea, and sometimes toxemia, vomiting, cramps, and tenesmus. Stools contain blood and mucous in a typical case. A search for possible sites of bacterial infection, together with cultures and blood smears, should be made. Presence of leucocytosis distinguishes bacterial infections from viral infections. |
| Others | Leptospirosis, viral hepatitis, rheumatic fever, and mononucleosis can produce signs and symptoms that may be confused with Ebola in the early stages of infection. |
