The Centers for Disease Control and Prevention issued new, tweaked guidelines for how states should handle travelers from Ebola-affected countries, but said measures taken by states such as New York and New Jersey go too far. The new guidelines separate travelers into four categories of risk, from high to low, but none suggest people should be kept forcibly quarantined unless they try to evade monitoring. Instead, those at highest risk should stay close to home and keep off public transport, and allow state or local health officials to check on them daily to make sure they are well.
