What Is Ebola?

Ebola virus disease is known by the other name Ebola hemorrhagic fever. It is a very rare disease but can cause severe complications resulting in death even. This virus gets transmitted to humans from wild animals. The mortality rate varies in different countries, but about 50 percent of the infected population is known to die. It can occur suddenly, resulting in detrimental effects. Earlier, when it occurred suddenly earlier, scientists and doctors were not able to study the virus properly. So, the disease led to uncontrollable outbreaks in 1976. This outbreak occurred in a village near the river called Ebola. That is how the disease gets this name. This virus belongs to a family called Filoviridae.

How Is the Ebola Virus Transmitted?

The specific wild animals from which the Ebola virus is transmitted are bats. These animals are the natural hosts. Once it affects an individual, it can quickly spread to others by direct contact with blood and other bodily secretions. It can also be transmitted from animals that were sick or dead.

  • When there are any open wounds or burns, then, it can get transmitted from the infected person to an uninfected one.

  • The objects that are contaminated by the affected person are called fomites. They could be anything such as the utensils, clothes, and the materials touched by the patient.

  • Unsafe sexual practices can also result in the transmission of the disease.

  • Healthcare workers are highly prone to Ebola virus disease. Patients are known to be infectious as long as the virus stays in the blood.

What Are the Risk Factors of the Ebola Virus Disease?

The risk factors of Ebola virus disease are:

  • Pregnancy- The virus continues to stay in the amniotic fluid for a long time. It can affect both the mother and fetus in the long run.

  • Breastfeeding- There is a possibility of the baby acquiring the virus from the lactating mother.

  • Medical Health Conditions- Having other health issues might reduce immunity levels in patients. This increases risk.

  • Multiple Sex Partners- The risk is relatively high in patients who are promiscuous.

What Is the Incubation Period for the Ebola Virus Disease?

The incubation period for this disease ranges from 2 days to 21 days. It is after this duration the symptoms start showing up. If a person is known to be affected by Ebola, he cannot transmit the infection until and unless the symptoms are visible.

What Are the Symptoms of the Ebola Virus Disease?

The symptoms of Ebola virus disease are:

How Is Ebola Virus Disease Diagnosed?

This disease is very difficult to diagnose because symptoms might resemble malaria, meningitis, fever, and typhoid. Ebola shows symptoms similar to the symptoms of pregnancy. The following tests are the best diagnostic methods for Ebola virus disease.

  • Serum Neutralization Test: A serum neutralization test can detect the presence of functional antibodies. This test can identify whether the virus particles have been neutralized by the medications.

  • Rapid Antigen Detection Test: This test is used only for screening purposes. Additional reactive tests should be used for confirmation.

What Are the Treatment Options for Ebola Virus Disease?

The possible treatment options are drug therapy and immunotherapy. In the recent outbreak from 2018 to 2019, a drug was identified, but the research is still under process. The treatment relies mainly on supportive care, which includes rehydration with intravenous and oral fluids. There is no proper treatment available for this disease. But it is possible to control the symptoms.

The two important aspects of treatment are:

  • Supportive Therapy: This might involve pain relief, offering comfort and counseling, and emotional support. Rehydration is constantly done and checked.

  • Intensive Care: This involves maintaining oxygenation for patients with lung disorders and maintaining ideal dialysis procedures for kidney failure patients.

What Are the Prevention Measures for Ebola?

Safeguarding pregnant women and breastfeeding mothers should take precedence over the remaining population. Vaccination should be made available to them first. Proper control of the outbreak depends on the intervention methods, proper surveillance of the cases, safe burial procedures of the dead, and isolation of the positive and suspected cases. Social distancing should be maintained, and gathering in common places should be avoided. Proper awareness is created among the public so that they will follow safe sanitation measures.

  • It is necessary to reduce the risk of transmission in animals such as monkeys, bats, apes, and porcupines.

  • Meat should be properly cooked and consumed. Fruits and vegetables should be thoroughly washed before cooking.

  • The second step is to reduce the risk of transmission among humans. This can be achieved by practicing proper protection measures. For maintaining correct hygienic practices, gloves, mouth masks, and goggles help. Regular hand washing should be practiced by the patients who are visiting the hospital. Hand Washing techniques should be followed by the persons delivering healthcare also.

  • If any of them are suspected, proper monitoring should be done by healthcare professionals for a minimum of 21 days. This is done to isolate any suspected positive case from healthy individuals.

  • Sexual contact can also be the reason for transmission. Safe sexual practices are to be followed. Contact with bodily fluids should be completely avoided.

  • In a healthcare setting, irrespective of the provisional diagnosis, all the instruments should be well sterilized. Sanitation should be followed throughout the hospital setup.

What Is the Vaccination for Ebola?

An experimental vaccine for Ebola was found to be very effective in guinea pigs during the year 2015. This vaccine showed a drastic change in the public. A vaccine called rVSV-ZEBOV was used during the last outbreak of the Ebola virus.

How Is the Prognosis?

Prognosis varies from one person to another. However, it is generally poor. If the virus has caused the destruction of the antibodies, then immunosuppression occurs. This reduces the capacity of the body to fight against the virus. But in most cases, if the infected person manages to survive, then it can indicate that the person might recover soon. Even after recovery, the person should follow up with their physician.

Conclusion:

Ebola virus disease known as Ebola hemorrhagic fever is a very rare disease. The virus gets transmitted to humans from wild animals. The disease is very difficult to diagnose because symptoms might resemble other conditions. The treatment options involve supportive therapy and intensive care. Taking proper preventive measures helps safeguard against infection.

Frequently Asked Questions

1.

What Is the Treatment for Ebola?

Ebola is a rare and deadly virus, and research is still going on to treat ebola. However, the symptoms can be managed by taking fluids and electrolytes either orally or intravenously. Medication can also reduce symptoms like vomiting, diarrhea, fever, or pain.

2.

What Are the Effects of Ebola on the Body?

The Ebola virus causes severe inflammation and tissue damage in the body. It is also known as hemorrhagic fever virus, as it can cause problems with the clotting system of the body and can cause internal bleeding.

3.

How Does Ebola Gets Transmitted?

Ebola does not spread through the air like other infections like the common cold. It can spread from one person to another when they come in contact with infected blood or body fluids. It is commonly seen in travelers, health workers, or the general public who do not care for being in close contact with the infected person.

4.

From Where Did Ebola Originate?

The Ebola virus was first discovered in the year 1976 near the Ebola river in the Democratic Republic of Congo. After that, the second outbreak occurred in South Sudan, approximately 500 miles away from the Ebola river. Since then, the ebola virus has infected people in several African countries.

5.

Can a Person Recovers From Ebola?

The recovery from ebola depends upon good supportive care and the immune system of the patient. Patients who recover can develop antibodies for ebola in the body, which can stay resistant for at least ten years or longer. However, even after recovery, some people may have complications such as joint and vision problems.

6.

What Organs Does Ebola Affect?

Ebola primarily affects the immune system of the body. In addition, it attacks the spleen and kidneys and kills the cells that regulate the fluid and chemical balance in the body. Moreover, it affects the blood clotting system of the body.
