The aid agency Concern has announced that one of its Liberian workers has died showing Ebola symptoms.
Definitive results on the cause of 42-year-old Dauda Konneh's death are expected in the next few days.
Concern says it's "deeply saddened" by the news- and says it's supporting his wife and two children at this "difficult" time.
Meanwhile another Irish agency, Goal, has appealed for medical workers to join them in their Ebola treatment centres in Liberia.
It comes as new figures from the US predict the virus could infect 1.4 million people in west Africa by January.
