Ebola virus (Phylovirus family)

Route of infection

Infection is caused mainly by contact with the patient’s body fluids (blood, secretions, vomitus, and excreta). Contact with the blood, secretions, excreta, and saliva of infected monkeys and other animals can also be acquired. Entry into caves in endemic areas is one of the risks of infection because of the risk of contact with infected bats.

Latent period

2-21 days (average of approximately one week)

Diagnosis and treatment

  1. Clinical symptoms

    The onset is sudden.Symptoms include fever, malaise, loss of appetite, and headache. It is followed by gastrointestinal symptoms such as vomiting, diarrhea, and abdominal pain. In severe cases, neurologic symptoms, hemorrhagic symptoms, and hypotension are observed, leading to death. Mortality rates vary by virus but are reported to be 80-90% high. Sequelae may include arthralgia, vision loss, and hearing loss.

  2. Diagnosis

    Detection of pathogens, pathogens, antigens or genes from blood, throat swab, and urine, detection of antibodies from serum

  3. Treatment

    Symptomatic therapy


Avoid traveling to endemic areas. Do not touch wildlife or patients directly. Don’t enter the cave.
