There is no specific antiviral drug proven to cure Yellow Fever, so treatment is entirely supportive, focusing on maintaining organ function and preventing complications while the immune system clears the virus; this includes fluids and electrolytes, oxygen support, paracetamol for fever and pain, careful avoidance of bleeding-risk medicines like aspirin and ibuprofen, close monitoring of liver, kidney, and clotting, and escalation to ICU care with ventilators, dialysis, or blood products if organ failure develops.
