daDALLAS — More than a week after a Liberian man fell ill with Ebola and four days after he was placed in isolation at a hospital in Dallas, the apartment where he was staying with four other people had not been cleaned and the sheets and dirty towels he used while sick remained in the home, health officials acknowledged on Thursday afternoon. Even as the authorities were reaching out to at least 80 people who may have had contact — either directly or indirectly — with the patient, Thomas E. Duncan, while he was contagious, they were scrambling to find medical workers to safely clean the apartment. The four family members who are living there are among a handful who have been directed by the authorities to remain in isolation, following what officials said was a failure to comply with an order to stay home. Texas health officials hand-delivered orders to residents of the apartment requiring them not to leave their home and not to allow any visitors inside until their roughly three-week incubation periods have passed.
