The course of treatment for hemorrhagic fever needs to be decided on a patient-by-patient basis, with most patients starting to recover gradually in 3-4 weeks, but recovery time is longer in severe cases, which may take 1-3 months or even longer. Renal syndrome hemorrhagic fever used to be also called epidemic hemorrhagic fever, or hemorrhagic fever for short, and is a common clinical infectious disease. Typical hemorrhagic fever is divided into a febrile phase, hypotensive shock phase, oliguric phase, polyuric phase and recovery phase. Therefore, for milder cases, recovery may be gradual in 2-3 weeks. For the vast majority of patients, recovery can begin in about 3-4 weeks. In addition, a few patients with severe cases have a longer recovery time and may require hospitalization for 15-30 days, with a recovery time of 1-3 months or more. Patients with hemorrhagic fever need to pay attention to strict bed rest and avoid handling to prevent shock. At the same time, a highly nutritious, vitamin-rich and easily digestible diet with mainly symptomatic treatment is given.
