Christie’s Quarantine Over-Reaction Ignores How Ebola is Transmitted
While Chris Chrisite toasted fellow quarantine advocate Rick Scott at a fundraiser in Florida, Kaci Hickox met with her attorney to prepare a legal challenge to her quarantine.
It’s really difficult to say which poor response to Ebola has done more damage to the public health system in the United States. First, we had the series of unforgivable errors at Texas Health Presbyterian Dallas that resulted in Thomas Duncan being sent home with Tylenol and antibiotics when he first presented with Ebola symptoms. This was followed up after he was admitted by Nina Pham and Amber Vinson coming down with the disease after they treated him. Now, we have Kaci Hickox, who treated Ebola patients in West Africa, confined to an unheated tent in a New Jersey hospital for 21 days even though she is asymptomatic and has tested negative for Ebola. Twice.
The hysteria over retracing the steps of Craig Spencer in New York City just before he developed his fever illustrates the way the US press has misled the public about when and where Ebola risk exists. Abundant evidence from this and previous Ebola outbreaks demonstrates clearly that there simply is no risk of transmission from asymptomatic patients and that transmission risk grows through the course of the infection.
We see that principle demonstrated very clearly in Duncan’s case history. See this terrific ABC timeline for relevant dates quoted below. Duncan arrived in Dallas September 20. No passengers on any of the flights he took have developed Ebola. The incubation period has elapsed, so we know that no transmission of the virus occurred during any of his flights. Duncan had symptoms on his first hospital visit on September 26 but was sent home. He was later admitted on September 28. No patients or personnel from the hospital became infected from his visit September 26. The incubation period has expired, so we know for certain that transmission did not occur for anyone near Duncan that day. Similarly, even though they were in the apartment with him for days after he developed symptoms, none of the residents of or visitors to the apartment where Duncan was staying in Dallas became infected. The incubation period for that exposure also has expired. From this timeline developed by the New York Times, it appears that Pham and Vinson treated Duncan on the day before he died, which would be at the time when the amount of virus being produced by his body was nearing its maximum.
The load of virus in a patient’s blood over the course of Ebola infection has been studied. In this CDC review, we have a graph showing the amount of virus over time: Read more →
