The statement that there are ten manifestations of hemorrhagic fever is unscientific. The symptoms of hemorrhagic fever are divided into early symptoms, middle symptoms and late symptoms. 1. Early symptoms: Early hemorrhagic fever patients appear similar to cold symptoms, such as runny nose, cough, fever and so on. Hemorrhagic fever can be confused with cold and acute nephritis, mainly because of the incubation period of hemorrhagic fever, which is about half a month. 2. Intermediate Symptoms: Patients may experience back pain, orbital pain and nausea, vomiting, chest tightness and other symptoms. This can be treated with fluid therapy, which keeps the body’s water and electrolytes in a balanced state. 3. Late symptoms: If hantavirus enters the body, it will cause fever, back pain and even generalized pain and other symptoms of poisoning, and patients with serious conditions will also have shock. If the patient has the above symptoms, consult a doctor in time to get a good treatment effect.
