Overview
The majority of differential diagnoses for Rift valley fever arise from other diseases which are prevalent in travelers and present with fever. All these disease would share a similar history of recent travel to an endemic area, followed by development of fever and body aches. A few of these diseases are listed below.
Differential Diagnosis
- Malaria
- The disease presents with fever like Rift valley fever, but the major difference is the pattern of fever in malaria. The fever recurs every 3-4 days in malaria while no such patterns are seen in RVF.
- Malaria is common in African countries, so paying attention to the time and onset of fevers can be useful in distinguishing between the two diseases.
- Typhoid fever
- Typhoid usually has a pattern of step-ladder form of fever, meaning the temperature rises with each passing day.
- The patient also complaints of bowel abnormalities along with fever. Individuals report either constipation or diarrhea along with fever.
- A rash is seen on the chest, known as rose-spots in patients with Typhoid.
- Crimean-Congo hemorrhagic fever
- It is a tick-borne viral disease of both wild animals and domestic animals, affecting humans.[1]
- The virus belongs to the Bunyaviridae family, which is commonly found in Africa.
- Risk factors include handling body fluids of infected humans or animals.
- Ebola virus disease
- Dengue
- Patients with dengue also complain of fever but have greater joint pains than in Rift valley fever.[2]
- A characteristic feature of dengue fever is retro-orbital pain.
- Dengue has a longer incubation period of 7 days, followed by a week of febrile phase, 1-2 days of the critical phase and 3-5 days of the recovery phase.
- Yellow fever
- Lassa fever
- The disease is usually seen in West Africa.[4]
- It is transmitted by rats and risk factors include handling food materials infected with rat feces or contact with infected humans.
- The incubation period ranges from 2-21 days and most of the people do not report any symptoms.
- Common symptoms are fever, throat pain, headache, swelling of the face, vomiting and diarrhea.
- Chikungunya
- It is caused by the Aedes aegypti mosquito and is commonly seen in African and Asian countries.[5]
- The course of the disease is self limiting and involves fever, headaches and generalized body pain.
- Q fever
- Q fever is caused by infection by a bacteria called Coxiella burnetii.[6]
- The bacteria is usually found in domestic animals such as sheep, goats, cats and ticks also.
- Risk factors include drinking raw milk, breathing in contaminated dust or droplets.
- Acute infection is characterised by fever, pneumonia and hepatitis. Chronic infections presents with cardiac, musculoskeletal or vascular symptoms.
- Zika virus
- Marburg virus disease
