HOUSTON -- The Centers for Disease Control is asking travelers to cancel non-essential trips to Liberia, Sierra Leone and Guinea.
The Ebola outbreak in West Africa has become a health crisis. There are now more than 1,300 confirmed cases and in the last four days, more than 700 people dead.
"Everybody is concerned for their family's life," said Monigo Saygbay-Halle, who moved from Liberia to Houston. "We're kind of helpless, there's nothing we can do."
The virus, which has a 90 percent mortality rate, has Saygbay-Halle canceling her family's travel plans to Africa and telling her cousin not to visit the US.
At Bush Intercontinental Airport, customs officials say they always monitor arriving international passengers for outward signs of sickness, but say they aren't doing anything out of the ordinary.
The CDC has a quarantine center to handle infected travelers.
The CDC has also advised airlines to be on the lookout for passengers from West Africa who might have jaundice, high fever and bleeding.
Ebola has a 21-day incubation period, it could be two weeks or more before a patient starts showing symptoms.
Health experts say that Ebola wouldn't spread as quickly in the US, because it has a much more advanced healthcare system.
Bush Intercontinental has a daily flight to and from Lagos, Nigeria. Nigeria, despite having a death related to Ebola, is not included in the CDC's travel advisory.
