No additional Ebola cases have been diagnosed in Texas in connection with a small outbreak earlier this fall, state health officials announced Thursday. The Texas Department of State Health Services touted the good news as the last person being monitored approached the end of the Ebola virus's 21-day incubation period. That person was not identified by name, but the health department said he or she was a hospital worker who handled potentially hazardous medical waste on Oct. 17. A total of 177 people were monitored due to contact with one of the state's three Ebola patients: Thomas Eric Duncan, a Liberian man who died of the disease; and nurses Nina Pham and Amber Vinson, who treated Duncan and have recovered.
