Ebola Outbreak Far Larger Than Reported

The World Health Organization warned that the Ebola outbreak in the Democratic Republic of Congo could be up to four times larger than official figures, as health workers strike over unpaid wages.

The WHO's head of Health Emergencies said the organization has less than half the funding required to mount an effective response.

The United States has barred Americans from returning home from Congo, requiring a 21-day stay in a third country even if they show no symptoms.

The convergence of funding shortfalls, labor unrest, and travel restrictions threatens to undermine containment efforts at a critical juncture.
