EbolaLate Friday, New York Gov. Andrew Cuomo and New Jersey Gov. Chris Christie imposed automatic, 21-day quarantines on anyone who has had contact or possible contact with infected people from Ebola-stricken countries in West Africa. And federal officials might issue formal quarantine guidelines for medical workers who treat Ebola patients in West Africa. The case of Craig Spencer, a doctor just returned to New York from Guinea in West Africa, the epicenter of the disease, spurred the newest spike in concern about the deadly virus’s potential spread in the United States. Spencer did not self-quarantine after arriving back in the country on Oct. 17. He also didn’t display any symptoms until late this week. On Wednesday, he rode the subway from Manhattan to a bowling alley in Brooklyn, then hired a car service to take him home. He woke up Thursday with a high fever and was diagnosed with Ebola that evening. New York City public-health officials are scrambling to clean up the locations Spencer has visited. They also placed his fiancée and two friends in quarantine. The hurried cleanup efforts in New York were in stark contrast with the mood in Washington. Here, public-health officials celebrated the recovery of Nina Pham, a nurse who contracted Ebola after treating Thomas Eric Duncan, the Liberian man who was the first diagnosed case on American soil and who later died; Pham even got to meet President Barack Obama on Friday before returning to Dallas. On Capitol Hill Friday morning, lawmakers held a hearing on the federal government’s response to the virus, but the tone was friendly compared to the grilling Obama administration officials received last week.
