Ebola is a highly infectious and often fatal disease that is caused by the Ebola virus. The disease was first discovered in 1976 when two outbreaks occurred in Sudan and the Democratic Republic of Congo (DRC).
Since then, there have been several outbreaks of Ebola in different parts of Africa, with the most recent outbreak occurring in the DRC in 2021. Understanding the basics of Ebola is crucial for preventing its spread and managing outbreaks.
What is Ebola?
Ebola is a viral infection that can cause severe hemorrhagic fever, which means that patients can experience bleeding from various parts of their body, including the eyes, ears, nose, and mouth.
The virus spreads through contact with bodily fluids of infected people or animals, such as blood, urine, saliva, and feces. The virus can also survive on surfaces and objects for several days, which means that it can be transmitted through contaminated objects. Symptoms of Ebola include fever, headache, muscle pain, fatigue, diarrhea, vomiting, and unexplained bleeding.
Where does Ebola come from?
Scientists believe that the Ebola virus is found in fruit bats that live in the rainforests of Africa. These bats can carry the virus without showing any symptoms of the disease.
When humans come into contact with infected bats or other animals that have come into contact with infected bats, they can contract the virus. Ebola can also spread from person to person through direct contact with bodily fluids or through contact with objects contaminated with infected bodily fluids.
How is Ebola treated?
There is no specific treatment for Ebola, but early and aggressive supportive care can improve the chances of survival.
This care includes fluids and electrolytes to prevent dehydration, oxygen to maintain blood oxygen levels, and medication to control fever. Patients with severe cases of Ebola may need additional treatment, such as blood transfusions, dialysis, or mechanical ventilation. Experimental treatments, such as antiviral drugs and monoclonal antibodies, have also been used to treat Ebola patients.
How can Ebola be prevented?
The best way to prevent Ebola is to avoid contact with infected people or animals.

People who live or work in areas where Ebola is present should wear protective clothing, such as gloves, masks, and gowns, when coming into contact with potentially infected bodily fluids or objects. They should also practice good hygiene, such as washing hands frequently with soap and water or using hand sanitizer.
Travelers to regions where Ebola is present should also take precautions, such as avoiding contact with animals, avoiding areas with large crowds, and avoiding contact with anyone who is sick.
What are the current Ebola outbreaks?
There are currently no active outbreaks of Ebola in the world. The most recent outbreak occurred in the DRC in 2021, but it was declared over by the World Health Organization in May of that year. The outbreak involved 12 confirmed cases and six deaths.
The DRC has experienced several Ebola outbreaks in recent years, including a major outbreak that began in 2018 and ended in 2020. That outbreak resulted in over 3400 confirmed cases and over 2200 deaths.
Why is Ebola so dangerous?
Ebola is dangerous because it is highly infectious and can cause severe hemorrhagic fever. The virus is also deadly, with a mortality rate of up to 90% in some outbreaks. This means that many people infected with Ebola die from the disease.
Ebola is also difficult to control because it can spread rapidly through contact with bodily fluids and can survive on surfaces and objects for several days. Containing an Ebola outbreak requires a coordinated effort from healthcare workers, public health officials, and the community.
Conclusion
Understanding the basics of Ebola is crucial for preventing its spread and managing outbreaks. The virus is highly infectious and can cause severe hemorrhagic fever, which can lead to death.
Ebola is transmitted through contact with bodily fluids of infected people or animals and can survive on surfaces and objects for several days. There is currently no specific treatment for Ebola, but early and aggressive supportive care can improve the chances of survival.
The best way to prevent Ebola is to avoid contact with infected people or animals through protective clothing and good hygiene practices.
