Thousands of Liberian health care workers are set to begin an indefinite strike at midnight on Monday that could undermine the country's effort to stop the spread of the deadly Ebola virus and leave several hundred patients without care.

Health workers in the West African nation threatened to abandon hundreds of patients in Ebola treatment units, clinics and hospitals if demands for better incentives, working conditions and protective equipment were not met.

A meeting to resolve their grievances on Oct. 10 ended in a deadlock with the government refusing the meet their demands, said George Williams, secretary general of the National Health Workers Association of Liberia.
