Ebola Virus Has Health Officials Concerned of Global Outbreak

Posted: Updated:
NBC RIGHT NOW-- Staff at the Centers for Disease Control and Prevention said two Americans have now been diagnosed with the deadly virus in Africa.

Despite airport screenings in West Africa, the CDC and the State Department are concerned the next outbreak of Ebola could be just one flight away.

The World Health Organization is calling this the largest outbreak of the disease ever recorded.

Federal health officials said there is little chance the virus will spread to the United States, but they are not taking any chances.

The virus is mostly found in tropical central and West Africa.  It is introduced through contact with infected animals like gorillas, fruit bats, and monkeys.

Ebola spreads through humans by contact with broken skin, bodily fluids or mucous membranes, and a person can still be contagious after death.

It can also take up to three weeks for symptoms to appear. Symptoms include sudden onset of fever, intense weakness, muscle pain, headache and sore throat. This is then followed by vomiting, diarrhea, rash, impaired kidney and liver function.

It also has a death rate between 50 and 90-percent and there are no specific treatments for the disease.

CDC staff said once the symptoms subside, the virus may no longer be contagious.
