CDC and Texas health officials said the nurse who became infected had been wearing the recommended personal protective gear for Ebola, which consists of gloves, a gown, a mask, and a shield to protect the eyes from possible splatters from the patient. According to experts, that gear offers
the minimum level of protection. When an Ebola patient enters the latter stages of the disease, as Duncan did, they become so-called fluid producers. Towards of end of the illness, the virus is trying to live and thrive. It's trying to get out of the person's body. It's producing massive amounts of fluid. At that point, caregivers need to add more layers of protective gear, such as double gloves and a respirator or a full bodysuit. Those kinds of decisions need to be made by managers who are constantly assessing the risk to healthcare workers.
