We can applaud health workers and take the prudent steps at the same time.
President Barack Obama and Kaci Hickox, a nurse who returned from treating Ebola patients in Sierra Leone on October 24, are attacking states’ efforts to keep returning health-care workers away from the public for 21 days. Governors in New Jersey, Illinois, Maine, Connecticut, and other states say it’s a wise precaution to prevent the virus from possibly spreading. But Obama claims that these regulations are based on fear, not science. And Hickox has successfully defied Maine’s effort to restrict her to her home, bashing the quarantine as “unnecessary” and “not evidence-based.” Judge Charles C. LaVerdiere ruled on Friday that Hickox is free to travel without restrictions.
But, in fact, science is against Obama, Hickox, and the judge. Evidence shows that to protect the public, travelers from Ebola-plagued West Africa, especially doctors and nurses who battled the virus, should be quarantined for 21 days.
FEVER MONITORING Is UNRELIABLE
At least 100 people, including about five health-care workers, enter the U.S. each day from Ebola-infected countries in West Africa. At departure from there and arrival here, their temperatures are checked by airport workers. But data from over 4,000 Ebola cases (the most complete analysis ever) published October 16 in the New England Journal of Medicine show that 13 percent of patients don’t develop a fever early on.
Thomas Duncan, who brought Ebola to Texas and infected two nurses, was able to get through fever screening. It also failed to identify Craig Spencer, the physician with Doctors without Borders, who returned home to New York infected with Ebola and then went bowling, dined out, and took the subway. Now he is fighting for his life in Bellevue Hospital, and public-health officials are scrambling to identify the people who may have been exposed to him.
Spiking temperatures eventually alerted Duncan and Spencer. But the research shows that in 13 percent of Ebola cases, the patient is already quite ill and diagnosed with the virus but still does not have a fever.
ARE AMERICANS AT RISK OF CATCHING EBOLA?
For most Americans, the known risk of catching Ebola is currently small. Ebola is most contagious in the later stages of illness, when victims here presumably would be in a hospital, putting hospital workers at severe risk but not the rest of us. Better sanitation facilities here than in Africa make it less likely that Americans will be exposed to infectious bodily fluids.
