About Ebola hemorrhagic fever

  • Ebola is a highly fatal infection caused by the Ebola virus.
  • When the body fluids (blood, secretions, vomit and excrement) of a patient with symptoms are touched without sufficient protection, the virus is transmitted by invading through wounds and mucous membranes.
    It is also transmitted from wild animals in endemic areas. Generally, it does not infect patients without symptoms. There is no airborne infection.
  • When infected with the Ebola virus, after an incubation period of 2 to 21 days (usually 7 to 10 days), symptoms such as sudden fever, headache, malaise, muscle pain, and sore throat appear.
    Next, symptoms such as vomiting, diarrhea, chest pain, and bleeding (hematosis, melancholy) appear.
