Aguirre said that she and others had not received proper training or personal protective equipment, and that the hospital had not provided consistent protocols for handling potential Ebola patients into the second week of the crisis.[66] A report indicated that healthcare workers did not wear hazmat suits until Duncan's test results confirmed his infection due to Ebola, two days after his admission to the hospital.[67] Frieden later said that the CDC could have been more aggressive in the management and control of the virus at the hospital.[68]
