3 Missionaries Return to US Feeling Upbeat Three missionaries who worked with patients infected with the Ebola virus in Liberia are back in the United States and feeling upbeat. President of the SIM USA mission, at a news conference said the three are amazingly vibrant. Although they were examined upon their arrival in North Carolina and declared healthy, they are being held in quarantine for at least three weeks dating from the time the missionaries were last exposed to people infected with the virus. The people in quarantine are having meals prepared on the SIM campus and brought to them. They can sit at same table, but with gaps between them. Source: NEWS24
