CDC recommends voluntary isolation for those at high risk of contracting Ebola

The US Center for Disease Control and Prevention (CDC) recommended voluntary home quarantine for people at the highest risk for Ebola infection.

CDC director Dr. Thomas Frieden said high risk individuals would include healthcare workers who tend to a patient without protective gear or suffer a needle stick while caring for a patient infected by Ebola.

Under new guidelines that spell out four risk categories, the majority of healthcare workers returning from the countries most affected by Ebola would be considered to at "some risk" for infection, while healthcare workers tending to Ebola patients at US hospitals would be seen as "low but non-zero" risk.
