Through the beginning of October, there have been 7,491 probable, confirmed and suspected cases of Ebola in West Africa, according to the latest "Ebola Response Roadmap" from the World Health Organization.

But the worldwide number is higher: For the first time during the deadliest Ebola outbreak in history, the WHO has included the United States on the "Ebola Response Roadmap," including the single case from Texas in its update.

According to the WHO's update, which was released Friday, the Ebola death toll is up to 3,439 in West Africa. All but eight of the deaths came in the Ebola-ravaged nations of Liberia, Sierra Leone and Guinea. (The others were in Nigeria, where the outbreak may be coming to an end.)

The number of U.S. Ebola cases remained at one through early Friday afternoon, even as health officials in Texas said that "approximately 10 people" who had contact with the Ebola patient in Dallas are considered higher risk. Also on Friday, Howard University Hospital in Washington said that a patient was being evaluated after coming to the facility "presenting symptoms that could be associated with Ebola."
