For critical Yellow Fever patients in the ICU, supportive care is essential to manage complications like liver failure, respiratory issues, and organ dysfunction. Life-support systems used may include ventilators to assist with breathing, dialysis for kidney failure, and blood transfusions for severe bleeding. IV fluids are also administered to maintain hydration and blood pressure. These treatments help stabilize the patient, as Yellow Fever has no specific cure, and support the body’s recovery during severe illness.
