The dangers of Ebola virus include severe clinical symptoms, high infectiousness, numerous sequelae and high morbidity and mortality. Ebola virus disease, once called Ebola hemorrhagic fever, is a virulent hemorrhagic infectious disease caused by the Ebola virus of the family of filoviruses, which leads to acute infection in humans. The course of the disease usually lasts for 5-15 days, with early symptoms such as rapid onset, sudden high fever, extreme malaise, severe headache, sore throat, generalized muscle and joint pain, and possibly chills and depression. The mortality rate of the disease is about 90%, usually 7-14 days after the onset of the disease, death from multiple organ failure and infectious shock and other complications. Non-serious patients generally begin to recover after 7-10 days, but their full recovery time is longer and they can develop various sequelae including deafness, arthritis, pericarditis and orchitis. Currently, an effective vaccine has been developed for the Ebola virus, and high-risk patients should be vaccinated as early as possible. After being infected with Ebola virus, one should go to the hospital in time, and standardize the treatment with the help of the doctor to alleviate the symptoms and save the life of the patient.
