EBOLA

What Is the Ebola Virus?

Ebola disease—also called Ebola hemorrhagic fever or Ebola fever—is a rare and often fatal illness that humans and nonhuman primates (such as monkeys and gorillas) can contract. There have been several outbreaks of Ebola fever in Africa. There has never been a reported case of Ebola fever in people in the United States.
The Ebola virus causes Ebola fever. The virus is found in Africa and the Philippines—but, the virus from the Philippines does not cause illness in humans. The virus was named after the Ebola River in the Democratic Republic of the Congo, where it was first discovered.
The Ebola virus was discovered in 1976 and has appeared in sporadic outbreaks since then. According to the Centers for Disease Control and Prevention, there have been 2,265 reported cases of Ebola fever in humans around the world since 1976. Of these, 1,531 resulted in death 
Types of Ebola Virus

There are five subtypes of Ebola virus:
  • Ebola-Zaire
  • Ebola-Sudan
  • Ebola-Ivory Coast
  • Ebola-Bundibugyo
  • Ebola-Reston

    What Are the Symptoms of Ebola Fever?

    If you are exposed to the any of the African forms of the Ebola virus, you will begin to display symptoms anywhere from two to 21 days following that exposure. The onset of the illness is rapid. The initial symptoms resemble those of a common flu infection and include:
    • fever
    • headache
    • sore throat
    • joint and muscle soreness
    • weakness
    As Ebola fever progresses, the symptoms become more severe. Late-stage symptoms of Ebola virus may include:
    • vomiting
    • diarrhea
    • redness in the eyes
    • swelling of the genitals
    • internal and external bleeding (some patients may have blood coming from their eyes,nosemouthears, or rectum)
    • a bleeding rash over the entire body

    How Is Ebola Fever Diagnosed?

    Ebola fever is diagnosed using blood tests to detect the Ebola virus in your blood. Your doctor may test you for the Ebola virus if you have symptoms of Ebola fever and have recently been in an area where the virus is found.
    How Is Ebola Fever Treated?
    There is no cure for Ebola fever. The only available treatments are those meant to help to ease your symptoms. These may include:There is no cure for Ebola fever. The only available treatments are those meant to help to ease your symptoms. These may include:
    • oxygen therapy
    • intravenous fluids
    • blood transfusions
    • medications to treat shock

FEVER



                                                        FEVER
fever -- also known as a high fever or a high temperature -- is not by itself an illness. It's usually a symptom of an underlying condition, most often an infection.
Fever is usually associated with physical discomfort, and most people feel better when a fever is treated. But depending on your age, physical condition, and the underlying cause of your fever, you may or may not require medical treatment for the fever alone. Many experts believe that fever is a natural bodily defense against infection. There are also many non-infectious causes of fever.
Fever is generally not considered dangerous, but hyperthermia can cause dangerous rises in body temperature. This can be due to an extreme temperature associated with heat injury such as heat stroke, side effects of certainmedications or illicit drugs, and stroke. With hyperthermia, the body is no longer able to control body temperature.
In children with fever, accompanying symptoms such as lethargy, fussiness, poor appetite, sore throatcough,ear pain, and diarrhea are important to relay to your doctor.
According to the American Academy of Pediatrics, if you have an infantyounger than 4 months old with a rectal temperature of 100.4 F or above, you should immediately call your doctor or go to an emergency room because it could be a sign of a potentially life-threatening infection. Also call your doctor or go to the emergency room if any child has a fever above 104 F. High fever can cause seizures in young children.
Call your doctor right away if your child has a fever and:
  • Looks very sick
  • Is drowsy or very fussy
  • Has a weakened immune system or other medical problems
  • Has a seizure
  • Has other symptoms such as rash, sore throat, headache, stiff neck, or earache
Call the doctor if the fever lasts more than 1 day in a child less than 2 years old or lasts more than 3 days in a child age 2 or older.

Causes of Fever

A part of the brain called the hypothalamus controls body temperature, which usually varies throughout the day from the normal temperature of 98.6 F.
In response to an infection, illness, or some other cause, the hypothalamus may reset the body to a higher temperature.
Although the most common causes of fever are common infections such as colds and gastroenteritis, other causes include:
  • Infections of the ear, lungskin, throat, bladder, or kidney
  • Conditions that cause inflammation
  • Side effects of drugs
  • Cancer
  • Vaccines
Other causes of fever include:

Diagnosis of Fever

Although a fever is easy to measure, determining its cause can be hard. Besides a physical exam, your doctor will ask about symptoms and conditions, medications, and if you've recently traveled to areas with infections or have other infection risks. A malaria infection, for example, may be have a fever that typically recurs. Some areas of the U.S. are hotspots for infections such as Lyme disease and Rocky Mountain spotted fever.
Sometimes, you may have a "fever of unknown origin." In such cases, the cause could be an unusual or not obvious condition such as a chronic infection, a connective tissue disorder, cancer, or another problem.
