U.S. Congressman Phil Roe is calling Ebola a lethal virus.
Ebola is only spread through bodily fluids or by using the same needles as someone with the virus, according to the Centers for Disease Control and Prevention.
The CDC also says that Ebola can travel quickly in hospitals if staff are not wearing gloves, masks and gowns.
Congressman Roe told us the outbreak makes border control even more important.
"We really have to be vigilant," said Roe. "I think certainly one of the debates we had last week in the U.S. Congress about border security is extremely important to know who's coming in and out of your country because they could be bringing this in."
The CDC says symptoms of Ebola include fever, headache, muscle aches, vomiting, and a lack of appetite. It can take up to 21 days for the symptoms to show up, according to the CDC.
