The Ebola outbreak continues to spiral out of control. Near the epicenter of the epidemic in West Africa, more than 3,400 people have died and more than 7,000 people have been infected with the virus. Officials are scrambling to contain the outbreak at its source and keep it from spreading.

The World Health Organization is sending doctors to countries where the virus is most prevalent — Liberia, Guinea, Sierra Leone and Nigeria. Fusion’s Jorge Ramos spoke to one of the doctors, Dr. Aileen Marty, who recently returned home to Miami after spending 31 days in Nigeria. She says she was surprised what happened when she arrived at Miami International Airport.

“I get to the kiosk…mark the fact that I’ve been in Nigeria and nobody cares, nobody stopped me,” Marty said.

“Not a single test?” Ramos asked her, surprised.

“Nothing,” Marty answered.

The White House recently announced it would implement additional measures for screening passengers coming into the U.S. from Ebola-stricken countries. New screenings will start at five major airports across the country, including New York’s John F. Kennedy International Airport, Newark Liberty International Airport, Dulles International Airport near Washington, D.C., Chicago’s O’Hare International Airport and Hartsfield-Jackson International Airport in Atlanta.

Travelers coming from West Africa will be taken to special screening areas to be examined for symptoms and questioned about any possible exposure they might have had to Ebola.

The decision came after Thomas Eric Duncan became the first Ebola patient on American soil to be diagnosed and die as a result of the disease. Duncan, a Liberian national, was diagnosed with the deadly virus on Sept. 30 in Dallas, days after he returned to the United States from Liberia. After a weeks-long struggle with the disease, he died on Oct. 8.

Dr. Marty says she was not surprised to hear about the first case of Ebola in the United States.

“If we don’t change our entry method and this outbreak continues to get completely out of control…it’s likely to be seen in other countries,” Marty warned.
