Which intervention is NOT required when dealing with hemorrhagic fever viruses?

The intervention that is not required when dealing with hemorrhagic fever viruses is respiratory isolation with positive-pressure rooms. Hemorrhagic fever viruses, such as Ebola or Marburg, primarily spread through direct contact with infected bodily fluids, such as blood, saliva, or other secretions, rather than through respiratory droplets. Therefore, the primary focus in managing care for patients with these viruses revolves around contact and droplet precautions rather than airborne precautions that would necessitate positive-pressure rooms.

Given this context, other measures, such as strict hand hygiene, protective eyewear, and contact isolation with double-gloving, are essential in preventing transmission of the virus when providing care to infected individuals. These protocols help to reduce the risk of exposure for healthcare workers and prevent the further spread of the virus to other patients and staff.
