one of the worlds deadleist viruses
It is believed that Ebola first emerged in Sudan and Zaire in 1976. Тhе name Ebola was named аftеr the Zaire River called "Ebola River". Тhе first outbreak of Ebola is sаіd tо have infected 284 people with а death rate of 53%.
The natural host of the Ebola virus remains unknown, but researchers believe that the virus is animal-borne.
The CDC recognizes that Ebola causes a lot of public worry and concern, but the CDC’s mission is to protect the health of all Americans, including those who may become ill while overseas. Ebola patients can be transported and managed safely when appropriate precautions are used.
Transmission and Risk
Because the host of Ebola viruses has not yet been identified, how the virus first appears in a human at the start of an outbreak is unknown. However, scientists believe that the patient becomes infected through contact with an infected animal.
When an infection does occur in humans, the virus can be spread in several ways to others. Ebola is spread through direct contact, for example, with:
Blood or body fluids (including urine, saliva, sweat, feces, vomit, breast milk, and semen) of a person who is sick with Ebola
Objects (like needles and syringes) that have been contaminated with the virus
One cannot be infected with Ebola through the air, water, or through food in the U.S.
Only mammals (for example, humans, bats, monkeys, and apes) have shown the ability to become infected with and spread Ebola virus.
Healthcare providers caring for Ebola patients and the family and friends in close contact with Ebola patients are at the highest risk of getting sick because they may come in contact with infected blood or body fluids of sick patients.
Exposure to Ebola can occur in healthcare settings where hospital staff are not wearing appropriate protective equipment, including masks, gowns, and gloves and eye protection.
Once someone recovers from Ebola, they can no longer spread the virus.
Symptoms of Ebola include:
Fever (greater than 38.6°C or 101.5°F)
Abdominal (stomach) pain
Unexplained hemorrhage (bleeding or bruising)
Symptoms may appear anywhere from two to 21 days after exposure to Ebola, but the average is eight to 10 days. Recovery from Ebola depends on good supportive clinical care and the patient’s immune response. People who recover from Ebola infection develop antibodies that last for at least 10 years.
There is no FDA-approved vaccine available for Ebola. If you travel to or are in an area affected by an Ebola outbreak, make sure to do the following:
Practice careful hygiene. For example, wash your hands with soap and water or an alcohol-based hand sanitizer and avoid contact with blood and body fluids.
Do not handle items that may have come in contact with an infected person’s blood or body fluids (such as clothes, bedding, needles, and medical equipment).
Avoid funeral or burial rituals that require handling the body of someone who has died from Ebola.
After you return, monitor your health for 21 days and seek medical care immediately if you develop symptoms.
