Liberia investigates how latest Ebola patient got infected

MONROVIA, Liberia — Liberia is investigating how its latest Ebola patient became infected, after weeks with no cases of the disease in the country.

The West African country has seen the most deaths in the Ebola outbreak, which has killed more than 10,000 people. But since it discharged its last case on March 5, it was counting down the 42 days that a country must wait in order to be declared Ebola-free.

But on Friday, officials said a new patient tested positive. In a worrying sign, she doesn't seem to be linked to any of the people on an Ebola contacts list and says she has not traveled recently to the neighboring infected countries of Sierra Leone and Guinea.

Officials are meeting Saturday to discuss the new case and how she became infected.
