Patient care
The sharing of body fluids and blood with another person constitutes close contact, as does the bathing, clothing, and toileting of the sick person. Close contacts with contagious people may need prophylactic treatment, quarantine, or observation to ensure their health and the health of others. Those who have casual contact with a sick person typically do not require these measures.
