The ones who might already have an infection or have a low immune level.
A nosocomial infection is one that a patient contracts while in the hospital.
A hospital-acquired infection is usually one that first appears three days after a patient is admitted to a hospital or other health care facility. Infections acquired in a hospital are also called nosocomial infections.
Nosocomial Infections are those that are hospital acquired, one which a patient catches during a hospital visit
Because the patient's immune system is suppressed, he or she is at an increased risk for infection.
I've never heard of a nos-comical infection, but I do know of nosocomial infections. Nosocomial infections are those acquired in a hospital during a hospital stay. For example, a patient spends a few days in a hospital for an appendectomy and acquires a MRSA or pseudomonas infection, thus making the stay longer. That is a nosocomial or hospital-acquired infection.
A person with AIDS is treated with antiviral drugs to control the viral infection. In addition, they require treatment or preventive medication for opportunistic infections.
Source isolation is stoping staff receiving an infection from a infected patient and protective isolation is to stop the patient receiving an infection from pathogens brought from outside the hospital via visitors etc...
Antibiotics kill bacteria. Antivirals kill viruses. However, a patient with a viral infection might sometimes be given antibiotics to reduce the work the patient's defenses have to do or to stop opportunistic infections.
The cilia prevent things from getting into the lungs, such as bacteria, so if they are paralyzed, they can't do that.
Inpatient services benefit a hospital the most.
Under the right conditions, yes, a hospital can keep you from seeing a patient. If the patient is contagious, is undergoing surgery, or is in ICU (which is the most probable reason), a hospital can keep you from seeing a patient.
Hospital confinement is preventing a patient from leaving the hospital.
