OMAHA, Neb. (AP) — The University of Nebraska Medical Center in Omaha has announced its dean of public health is in Sierra Leone to help the World Health Organization respond to the Ebola outbreak in West Africa.

Ali S. Khan left Tuesday for the assignment, flying first to Geneva to meet with officials at the WHO headquarters. He then flew on Sierra Leone.

Earlier this month, UNMC joined the WHO’s Global Outbreak Alert and Response Network. Khan was then directed through a medical assessment and security training. He will assist with exploring the dynamics of the disease in the country and reviewing prevention strategies in support of the WHO country office for the next four to six weeks.
