In the United States, the Centers for Disease Control and Prevention has unveiled new protocols for healthcare workers treating patients with Ebola. The guidelines include training for staff and supervision for workers as they remove their protective gear. The steps come after two nurses became infected with Ebola while treating a patient in Dallas. On Monday, 43 people who had been in contact with the initial patient, Thomas Eric Duncan, were cleared from Ebola monitoring after the 21-day incubation period. About 75 healthcare workers involved in Duncan’s care are still being monitored.
