On Tuesday, the Centers for Disease Control and Prevention reported that Thomas E. Duncan, who traveled from Liberia to Dallas, tested positive for Ebola. Director of the C.D.C., Dr. Thomas R, Frieden, reported that the odds of contracting Ebola in the US are still extremely low. Health officials say that they are confident that the current protocol for controlling infectious diseases would contain Ebola.
Ebola is spread through direct contact with body fluids. People are only infectious if they have symptoms of the disease, and there is no risk of transmission from people who have been exposed but don’t show symptoms.
Since March, more than 7,400 people have contracted Ebola. Ebola has a fatality rate of 50 to 90 percent, and more than 3,400 people have died from the disease. The World Health Organization says this is the biggest outbreak on record since the discovery of the disease in 1976.
