Patient #2 in Dallas

The math just got worse:

A second health care worker at a Dallas hospital who provided care for the first Ebola patient diagnosed in the U.S. has tested positive for the disease, the Texas Department of State Health Services said Wednesday. The department said in a statement that the worker reported a fever Tuesday and was immediately isolated at Texas Health Presbyterian Hospital in Dallas. Health officials said the worker was among those who took care of Thomas Eric Duncan, who was diagnosed with Ebola after coming to the U.S. from Liberia. Duncan died Oct. 8.

The department said a preliminary Ebola test was conducted late Tuesday at a state public health laboratory in Austin, Texas, and came back positive during the night. Confirmatory testing was being conducted at the federal Centers for Disease Control and Prevention in Atlanta…. Officials have said they don’t know how the first health worker, a nurse, became infected. But the second case pointed to lapses beyond how one individual may have donned and removed personal protective garb.

Two patients in the USA in Spain, two deaths, three health care worker infections. This is not reassuring. As I, and every other sane Westerner said at the time, infected aid workers should have been left to their fates in Africa, where they were infected.

UPDATE: The news just gets better:

 The CDC has announced that the second healthcare worker diagnosed with Ebola — now identified as Amber Joy Vinson of Dallas — traveled by air Oct. 13, the day before she first reported symptoms. The CDC is now reaching out to all passengers who flew on Frontier Airlines flight 1143 Cleveland to Dallas/Fort Worth. The flight landed at 8:16 p.m. CT. The CDC is asking all 132 passengers on the flight to call 1 800-CDC INFO.
