Medics treating cases of Marburg fever in Angola say a hospital at the center of the outbreak should be closed to all non-emergency patients to stop the disease from spreading.

Doctors Without Borders, a global relief organization, recommends suspending non-emergency services at the hospital in Angola's northwestern Uige province, where victims of the fatal virus are being held in isolation.

The organization's emergency coordinator in Uige says this step is necessary to reduce infection risks.

So far, Marburg fever has killed at least 192 of the more than 200 people known to be infected.

The Ebola-like hemorrhagic fever spreads through contact with bodily fluids, and can kill rapidly.

The World Health Organization has sent in teams to remove bodies and trace contacts with infected patients.
