Thomas Eric Duncan was a 42-year-old Liberian man who traveled to the United States in September 2014. Upon arrival in Dallas, Texas, he began to show symptoms of Ebola after having come into contact with another Ebola patient in Liberia. He sought medical attention but was initially sent home with antibiotics. As his condition worsened, he was eventually admitted to Texas Health Presbyterian Hospital, where he was diagnosed with Ebola on September 30, 2014, becoming the first confirmed case of the virus in the U.S. His diagnosis prompted a significant public health response, including contact tracing and monitoring for potential cases among those who had interacted with him.Despite receiving aggressive treatment, Thomas Duncan succumbed to the illness on October 8, 2014. His death raised concerns about the preparedness of U.S. healthcare facilities to handle infectious diseases, particularly in the context of the ongoing Ebola outbreak in West Africa. The hospital faced scrutiny over its initial handling of Duncan's case, which included a delay in diagnosis and the adequacy of their protocols for dealing with highly contagious diseases. This situation accelerated discussions involving federal and state health agencies about Ebola preparedness and response mechanisms.
