The CDC is out with a travel warning today as the deadliest outbreak of Ebola in history continues to march across West Africa. Health officials say all non-essential travel to Liberia, Sierra Leone and Guinea should be canceled. The death toll in that region is approaching 750, which includes one American. Two more U.S. citizens are infected and a couple of Peace Corps volunteers have apparently been exposed, although there are very few details on their conditions.

In issuing the advisory against travel to affected areas, CDC director Thomas Frieden said it's becoming clear that "Ebola is worsening in West Africa." He also announced that 50 additional staffers from the Centers for Disease Control and Prevention are being sent in to help countries in the region find ways to better control the potentially-deadly virus.

Also, the U.S. has no plans to close embassies in West African nations affected by the deadly Ebola outbreak.  State Department spokesperson Marie Harf said during Thursday's briefing there's no change in the status of the American embassies in Liberia, Sierra Leone and Guinea and that staff is not being reduced.  She said the U.S. is working on getting "aviation assistance" to help get infected Americans back home and that every precaution will be taken to "maintain strict isolation" upon their arrival in the United States.  (Metro Networks Inc.)
