The infected person was moved to Monrovia, said deputy health minister Tolbert Nyenswah.
Between 100 and 200 Ebola center workers stormed the Ministry of Health in eastern Monrovia on Wednesday demanding hazard pay that they said they haven't received since the country was declared Ebola-free by the World Health Organization on May 9.
Protesters turned off the building generator, an official, who spoke on condition of anonymity for security reasons, told The Associated Press.
