Viral Hemmorhagic Fever
The symptoms described are suggestive of viral hemorrhagic fever, particularly due to infections like Ebola or Marburg virus, which are endemic to parts of Africa. The combination of fever, hypotension, conjunctival injection, and a rash that bleeds indicates a severe viral infection that affects vascular integrity. Immediate medical attention is crucial, as these infections can be life-threatening.

The patient's symptoms, particularly following recent travel to Africa, raise suspicion for a viral illness such as Ebola or Marburg virus disease, both of which can present with fever, hypotension, and conjunctival injection. Other considerations include yellow fever or dengue fever, but the conjunctival injection is particularly notable. Immediate isolation and notification of public health authorities are crucial for management and to prevent potential outbreaks. Further diagnostic testing is necessary to confirm the specific infection.
Based on the symptoms of fever, mild hypotension, flushing, and conjunctival injection, the patient may be experiencing a viral hemorrhagic fever, with yellow fever or dengue fever being potential considerations given his recent travel to Africa. These conditions can manifest with similar presentations and require prompt diagnosis and management. Further investigation, including travel history, laboratory tests, and possibly serology, will be essential in confirming the diagnosis and providing appropriate treatment. Immediate supportive care and isolation may also be necessary to prevent potential spread.
What test is used to diagnose viral hemorrhagic fever
Viral hemorrhagic fevers which are a diverse group of animal and human illnesses in which fever and hemorrhage are caused by a viral infection. They may be caused by five distinct families of RNA viruses: the families Arenaviridae, Filoviridae, Bunyaviridae, Flaviviridae, and Rhabdoviridae (according to Wikipedia).
A patient presents to the hospital. He has been feeling ill since his return from safari in Africa a few days ago. He exhibits symptoms of fever, mild hypotension, flushing, conjunctival injection, and now a bad rash has appeared that is bleeding in spots. What type of viral infection do you suspect?

Yellow fever
Viruses of the Arenaviridae family cause the Argentinian, Brazilian, Bolivian, and Venezuelan hemorrhagic fevers. Lassa fever, which occurs in west Africa, also arises from an arenavirus.
