How to distinguish between Oropouche fever and dengue?

Question

Hello doctor,

I am concerned about some recent symptoms I have been experiencing, including a high fever, severe headaches, joint pain, and a skin rash. I recently traveled to areas where Oropouche and dengue fever are prevalent. I have read about the Oropouche orthobunyavirus and am worried I might have contracted it. Could you explain how the symptoms of Oropouche fever differ from those of dengue fever? Also, what specific tests should I request to determine which virus I might have? Lastly, I would like to know about the treatment options for both diseases. Any insights would be appreciated.

Thank you.

Hi,

Welcome to icliniq.com.

I read your query and can understand your concern.

Given the overlapping symptoms, it is essential to conduct specific tests to differentiate between Oropouche fever and dengue fever.

Oropouche fever, caused by the Oropouche orthobunyavirus, typically presents with sudden high fever, severe headaches, joint and muscle pain, and sometimes a rash. It can lead to neurological symptoms like meningitis in some cases. The intense fever and joint pain usually resolve within a week.

Dengue fever, caused by the dengue virus, also presents with high fever, severe headaches (often behind the eyes), joint and muscle pain, and a rash. Dengue is known for causing 'breakbone fever' due to the severe pain it induces. It is important to note that severe forms of dengue can include dengue hemorrhagic fever, which involves bleeding and plasma leakage, or dengue shock syndrome (a severe form of dengue fever), which can be life-threatening.

To determine which virus you might have, the following tests are recommended:

The dengue NS1 (non-structural protein 1) antigen test and dengue IgM (immunoglobulin M) and IgG (immunoglobulin G) antibodies are needed for dengue fever.
For Oropouche fever, a PCR (polymerase chain reaction) test is used to detect the virus.

Treatment for both diseases is mainly supportive, including rest, fluids, and pain relievers like Acetaminophen. Avoid Aspirin and NSAIDs or nonsteroidal anti-inflammatory drugs, especially for dengue, due to the risk of bleeding.

Please get tested to confirm the diagnosis and receive appropriate care.

I hope this helps.
