1. Patients suffering from infectious diseases should be quarantined in case of cross - infection .

2. Trichomonas vaginitis due to cross - infection is very high, it can easily relapse.

3. Much of this success can be attributed to sustained cattle controls reducing cross-infection and breaking the disease cycle.

4. These studies, as well as the reduction in the risk of cross-infection, encouraged the use of paper cups in hospitals.

5. The circular plan was derived from the hospital tents of the Crimea, where improved ventilation helped reduce the risk of cross-infection.

6. Cross infection between patients and nurses in a pediatric intensive care unit (PICU) provided clear evidence that PICU HCWs risk acquiring serious herpetic infections, i.e. acute pharyngitis or whitlow from patients and vice-versa unless careful attention to infection prevention and control is practised(163).
