CHARLOTTE, N.C. (AP) — Two North Carolina-based missionary groups have ordered the evacuation of their non-essential personnel from Liberia after a doctor and a missionary contracted Ebola.

SIM USA President Bruce Johnson announced Tuesday that his group and Samaritan’s Purse decided on the evacuation following an upsurge in the number of Ebola cases in Liberia. Johnson said the logistics of the evacuation are being determined.

Spokesman Palmer Holt said approximately 60 employees will be evacuated. A statement from SIM says none of the evacuees is displaying any symptoms of Ebola, but all are being monitored continually.

A Texas-trained doctor and a missionary from Charlotte have contracted the disease.
