This month, the state began monitoring all travelers from Guinea, Liberia or Sierra Leone by placing them into one of three groups based on their risk of contracting the virus. Health workers and others exposed to Ebola patients without wearing protective equipment could face home quarantine, while those who wore proper masks and gowns are being asked to avoid public transit and mass gatherings. All travelers from the three countries are being required to communicate frequently with state health officials and take their temperatures regularly.
