[6M] With persistent high fever and multisystem symptoms

What might be happening

Based on the symptoms you've described for your son, there are several possibilities:

• Infectious Mononucleosis: This is a viral infection that can cause fever, sore throat, fatigue, and swollen lymph nodes in the neck. It's most commonly caused by the Epstein-Barr virus.

  • Treatment typically involves rest, hydration, and over-the-counter remedies for pain and fever.

• Hepatitis: This is inflammation of the liver, which can be caused by a viral infection, alcohol use, or certain medications. The copper-colored urine and abdominal pain could be due to liver dysfunction.

  • Treatment depends on the cause and severity of the hepatitis.

• Hemolytic Uremic Syndrome: This is a condition that affects the blood and blood vessels, resulting in the destruction of blood platelets (cells involved in clotting), a low red blood cell count (anemia), and kidney injury. It's most commonly caused by a specific strain of E. coli bacteria.

  • Treatment usually involves hospitalization, and often includes blood transfusions and kidney dialysis.

What you can do

Given the severity and duration of your son's symptoms, it's important to seek immediate medical attention. His doctor will likely want to perform a variety of tests to determine the cause of his symptoms, including blood tests, a throat swab, and possibly imaging studies or a biopsy of the lymph nodes or liver.

What you should look out for

If your son's symptoms worsen or if he develops new symptoms such as severe abdominal pain, difficulty breathing, or a change in consciousness, you should seek emergency medical attention.
