Ebola virus disease is prevalent in the Democratic Republic of the Congo (DR Congo) and Guinea.

As of the 15th, 2 out of 4 people died in DR Congo, showing a fatality rate of 50%, and in Guinea, 3 out of 7 people died, reaching a fatality rate of 42.9%.

The fatality rate of Ebola virus disease varies depending on the type of virus and the level of health care system in each country, but it has a high fatality rate of 25 to 90% overall.

Therefore, it is important to follow precautions to prevent infection with the Ebola virus.

Ebolavirus disease is an acute febrile hemorrhagic disease caused by an Ebolavirus infection. It was first reported in South Sudan and villages near the Ebola River in DR Congo in 1976, and thereafter, a large outbreak occurred in African countries. In addition to Africa, the disease has been introduced to Italy, Spain, the United Kingdom, and the United States.

The path of infection is transmitted from animals to humans and from humans to humans. Direct contact with animals such as fruit bats, monkeys, gorillas, chimpanzees, and antelopes infected with Ebola virus in epidemic areas can cause infection, and it can also occur when contacting blood, body fluids, and injured skin or mucous membranes of Ebola virus patients. . Sexual contact with a patient recovering from Ebola virus can also cause infection, and there is also the possibility of infection by breastfeeding or aerosol.

Symptoms are usually manifested after an incubation period of 2 to 21 days, but infection can be transmitted after symptoms begin. Initial symptoms include fever, loss of appetite, weakness, weakness, general weakness, muscle pain, headache, and other non-specific symptoms, followed by gastrointestinal symptoms such as nausea, vomiting, diarrhea, and abdominal pain, and bleeding symptoms. In addition, a decrease in white blood cells, a decrease in platelets, and an increase in liver enzyme levels are confirmed in hospitals, and specific genes are detected in samples such as blood and body fluids through diagnostic tests.

Treatment includes symptomatic treatment and treatment (Inmazeb, Ebanga, etc.). In epidemics in Africa, recently developed vaccines are sometimes applied to respond to epidemics. In Korea, the Korea Centers for Disease Control and Prevention is stockpiling 100 medical treatments for the treatment of Ebola virus patients.

To prevent Ebola virus, you should refrain from visiting epidemic areas. In addition, precautions such as washing hands, avoiding contact with mucous membranes with contaminated hands, and wearing personal protective equipment during patient care should be observed.

If you visit an epidemic area under unavoidable circumstances, contact with bats, primates, and animal carcasses should be prohibited and avoid eating such animal meat. Local visits to medical institutions should be refrained from, and contact with Ebola virus patients or persons with suspicious symptoms should be prohibited. People who have died from suspected symptoms of Ebola virus should also refrain from attending the funeral.

When returning home after visiting an epidemic area, submit a health status questionnaire to the quarantine officer, and if related symptoms such as fever occur within 21 days, contact the Centers for Disease Control and Prevention call center or health center for consultation.
