CDC confirmed on September 30, 2014, through laboratory tests, the first case of Ebola to be diagnosed in the United States in a person who had traveled to Dallas, Texas from West Africa. The patient did not have symptoms when leaving West Africa, but developed symptoms approximately four days after arriving in the United States.
The person sought medical care at Texas Health Presbyterian Hospital of Dallas after developing symptoms consistent with Ebola. Based on the person’s travel history and symptoms, CDC recommended testing for Ebola. The medical facility isolated the patient and sent specimens for testing at CDC and at a Texas lab participating in CDC’s Laboratory Response Network. CDC and the Texas Health Department reported the laboratory test results to the medical center to inform the patient. Local public health officials have identified all close contacts of the person for further daily monitoring for 21 days after exposure. He died of Ebola on October 8 and was cremated.
The patient did not exhibit symptoms of Ebola during the flights from West Africa and CDC does not recommend that people on the same commercial airline flights undergo monitoring, as Ebola is only contagious if the person is experiencing active symptoms. The person reported developing symptoms several days after the return flight.
CDC recognizes that even a single case of Ebola diagnosed in the United States raises concerns, and even one death is too many. Medical and public health professionals across the country have been preparing to respond. CDC and public health officials in Texas are taking precautions to identify people who had close personal contact with the patient and health care professionals have been reminded to use meticulous infection control at all times.
We know how to stop Ebola’s further spread: thorough case finding, isolation of ill people, contacting people exposed to the ill person, and further isolation of contacts if they develop symptoms. The U.S. public health and medical systems have had prior experience with sporadic cases of diseases such as Ebola. In the past decade, the United States had 5 imported cases of Viral Hemorrhagic Fever (VHF) diseases similar to Ebola (1 Marburg, 4 Lassa). None resulted in any transmission in the United States.
