CHARLOTTE, North Carolina (AP) -- Health officials say missionaries retuning to the United States after working with patients infected with Ebola will be put in quarantine and monitored.
The North Carolina Department of Health and Human Services says the quarantine will last at least three weeks since the missionaries were last exposed to people infected with the Ebola virus.
The missionaries are with Charlotte-based SIM USA. The aid group says none of them are sick or have shown any signs of having Ebola, but they agree with health officials that everyone should be as cautious as possible.
The aid group isn't releasing how many missionaries were in Liberia or when they will return to protect the privacy of their families.
