Ebola Virus Infection
Ebola
is a rare but deadly infection that causes bleeding inside and outside
the body. Although popular movies and books describe major outbreaks of
ebola-like disease in the U.S., they're just works of fiction. Ebola
strikes mainly in remote villages of Central and West Africa, but it has
spread to some African cities, too.
The disease, also known as Ebola hemorrhagic fever or Ebola virus disease, kills up to 90% of people who are infected.
Dengue Fever
Dengue
(pronounced DENgee) fever is a painful, debilitating mosquito-borne
disease caused by any one of four closely related dengue viruses. These
viruses are related to the viruses that cause West Nile infection and
yellow fever.
Each year, an estimated 100 million cases of dengue fever occur
worldwide. Most of these are in tropical areas of the world, with the
greatest risk occurring in:
The Indian subcontinent
Southeast Asia
Southern China
Taiwan
The Pacific Islands
The Caribbean... Continue reading.........
How Do You Get Ebola?
You can get Ebola by coming into contact with the blood or body fluids of an animal or person who is infected.
People
often get sick with Ebola when they care for or bury a person who has
the disease. Someone also can catch the virus by touching contaminated
needles or surfaces.
What Are the Symptoms of Ebola?
Symptoms
of the Ebola virus show up 2 to 21 days after someone is infected. As
the virus spreads through the body's cells, it damages the immune system
and organs. Ultimately, Ebola causes levels of blood-clotting cells,
called platelets, to fall, which can lead to severe bleeding.
Many of the early symptoms of Ebola look like the flu or other mild illnesses. They include:
- Fever
- Headache
- Muscle aches
- Sore throat
- Weakness
- Diarrhea
As the disease gets worse, people who are infected may develop:
- Bleeding inside and outside of the body
- Rash
- Trouble breathing
How Can You Tell if Someone Has Ebola?
Sometimes it's hard to tell if a person has Ebola from the symptoms alone.
Doctors may first test for other diseases that have the same symptoms as Ebola, such as:
- Cholera
- Hepatitis
- Malaria
- Meningitis
- Typhoid fever
Tests of the blood and tissues, such as the ELISA test, also can help diagnose Ebola.
If someone might have Ebola, they should be isolated from the public immediately to help prevent the spread of Ebola.
How Is Ebola Treated?
Right now there is no real treatment or cure for Ebola. Doctors try to manage people's symptoms by giving them:
- Fluids and electrolytes through a vein
- Nutrition
- Oxygen
How Can You Prevent Ebola?
There is no vaccine to prevent Ebola. People can avoid catching the disease by not traveling to areas where the virus is found.
Health
care workers can prevent infection by wearing masks, gloves, and
goggles whenever they come into contact with people who may have Ebola.
What Causes an Ebola outbreak?
Usually
an outbreak starts when someone comes into contact with the body fluids
or waste of infected animals, such as monkeys, chimps, or fruit bats.
Once a person is infected, he or she can then spread it to others.
There are five different types of Ebola virus that cause the disease. Four of them are known to cause the disease in humans.
The Ebola virus first appeared during two 1976 outbreaks in Africa.
Ebola
gets its name from the Ebola River, which is near one of the villages
in the Democratic Republic of Congo where the disease first appeared.
