The fifth American to catch the deadly Ebola virus arrives in the United States to receive treatment.

Ashoka Mukpo, a 33-year-old American freelance cameraman who contracted Ebola in Liberia, was taken Monday to a hospital in the Midwestern state of Nebraska.

He will be kept in a specialized containment unit built specifically for this type of disease.

The medical center previously treated a US doctor who was also infected with Ebola in Liberia.

Mukpo, who had worked on humanitarian projects in Liberia for several years, was hired by NBC News last week.

He later kept himself in quarantine as he came down with symptoms of the virus. The other crewmembers are being closely monitored.

The arrival of Mukpo in the US comes as the first person diagnosed with the deadly virus in the United States “is fighting for his life.”

Officials from Texas Health Presbyterian Hospital Dallas said Sunday that Thomas Eric Duncan’s condition had worsened from “serious” to “critical” on Saturday.

According to the World Health Organization, Ebola has claimed over 3,400 lives in West Africa including Liberia, Guinea and Sierra Leone, with Liberia accounting for about two-thirds of the deaths.

There is currently no known cure for Ebola, which is a form of hemorrhagic fever with diarrhea, vomiting and bleeding as its symptoms.

The Ebola virus spreads through direct contact with infected blood, feces or sweat. It can also be spread through sexual contact or unprotected handling of contaminated corpses.
