1.
Where is the Ebola outbreak most widespread?
Correct Answer
E. West Africa
Explanation
The Ebola outbreak is most widespread in West Africa. This region has been particularly affected by the virus, with countries such as Guinea, Sierra Leone, and Liberia experiencing significant outbreaks. The outbreak in West Africa started in 2014 and lasted until 2016, resulting in thousands of deaths and causing a global health emergency. The high population density, inadequate healthcare infrastructure, and cultural practices in this region contributed to the rapid spread of the virus. Efforts to contain and control the outbreak involved international aid, medical interventions, and public health campaigns.
2.
Which one of the following countries have been issued a travel warning?
Correct Answer
C. Liberia
Explanation
Liberia has been issued a travel warning.
3.
Which virus causes Ebola?
Correct Answer
A. RNA virus
Explanation
Ebola is caused by an RNA virus. RNA viruses are a type of virus that use RNA as their genetic material instead of DNA. Ebola is specifically caused by the Ebola virus, which belongs to the family Filoviridae and the genus Ebolavirus. This virus is responsible for causing severe and often fatal hemorrhagic fever in humans.
4.
Which symptom is common in the later stages of Ebola?
Correct Answer
D. Bleeding
Explanation
Bleeding is a common symptom in the later stages of Ebola. As the virus progresses, it can cause damage to blood vessels and impair the blood's ability to clot, leading to internal and external bleeding. This can manifest as bleeding from the gums, nose, eyes, or other parts of the body. It is a severe and often life-threatening symptom of the disease.
5.
Where did the first known Ebola outbreak occur in 1976?
Correct Answer
F. Democratic Republic of Congo
Explanation
The first known Ebola outbreak occurred in the Democratic Republic of Congo in 1976. This outbreak, which occurred in a village near the Ebola River, gave the virus its name. The outbreak affected both humans and animals, with a high mortality rate. The virus was initially mistaken for other diseases such as malaria and typhoid, making it difficult to identify and contain. Since then, the Democratic Republic of Congo has experienced several Ebola outbreaks, highlighting the ongoing challenge of controlling the virus in the region.
6.
Which of the following is NOT one of the symptoms of Ebola?
Correct Answer
D. Weight loss
Explanation
Weight loss is not one of the symptoms of Ebola. Ebola is characterized by symptoms such as high fever, muscle aches, headache, sore throat, and weakness. While weight loss can occur as a result of the disease, it is not considered a primary symptom.
7.
How does the Ebola virus spread?
Correct Answer
A. Close contact with skin and bodily fluids
Explanation
The Ebola virus spreads through close contact with the skin and bodily fluids of an infected person. This can occur through activities such as touching, hugging, or caring for someone who is infected, as well as through contact with contaminated objects or surfaces. It is important to note that the virus is not spread through casual contact or through the air.
8.
After how many days do Ebola symptoms start appearing?
Correct Answer
C. Two days
Explanation
Ebola symptoms typically start appearing after two days. This is the average incubation period for the virus, although it can range from 2 to 21 days. During this time, an infected person may not show any signs of illness but can still spread the virus to others. After the incubation period, symptoms such as fever, headache, muscle pain, fatigue, and sore throat may develop. As the disease progresses, more severe symptoms like vomiting, diarrhea, rash, impaired kidney and liver function, and in some cases, internal and external bleeding, may occur.
9.
There is no treatment or cure for Ebola. However, there are treatments that can make patients more comfortable. What kind of treatment does this include?
Correct Answer
B. Intravenous (IV) fluids
Explanation
The treatment for Ebola includes intravenous (IV) fluids. This means that patients are given fluids directly into their veins to help replace the fluids and electrolytes that are lost due to the illness. IV fluids can help to rehydrate the patient and maintain their blood pressure. This treatment can make patients more comfortable and help support their body's ability to fight off the virus.
10.
Which animal is considered a natural Ebola virus host?
Correct Answer
E. Fruit bat
Explanation
Fruit bats are considered a natural Ebola virus host because they are known to carry the virus without showing any symptoms. They are believed to be the primary reservoir for the virus and can transmit it to other animals or humans through their saliva, urine, or feces. Fruit bats are commonly found in Africa, where Ebola outbreaks have occurred, and their close proximity to human settlements increases the risk of transmission. Understanding the role of fruit bats in the Ebola virus transmission is crucial for preventing future outbreaks and implementing effective control measures.
