Contact 传染的病毒， 太多了；
病人的排泄物（ patients with norovirus, rotavirus, or Clostridium difficile）
伤口流出物 Draining wounds,
分泌物 Uncontrolled secretions
任何其他体液血液（Pressure ulcers, or presence of ostomy tubes and/or bags draining body fluids）
等等， 都可以导致传染：
预防：
Wear gloves -- when touching the patient and the patient’s immediate environment or belongings
Wear a gown --- if substantial contact with the patient or their environment is anticipated
Hand wash —— befor and after
。。。。。
