The key difference between cross infection and secondary infection is that cross infection refers to the transfer of harmful microorganisms from another person, medical equipment or tools while secondary infection is an infection that occurs during or after treatment for another infection.
Infections can be prevented via maintaining clean and thoroughly sanitized areas around patients. Hence, doctors wash their hands frequently. Moreover, sterile environments are maintained inside the hospitals. Cross infection and secondary infection are two types of infections from which patients should be saved.
