How to interrupt the Chain of Infection | The essential part of patient care and self protection |
How to interrupt: Infectious Agent | Identification of infection and appropriate treatment |
How to interrupt: Reservoir | Asepsis and hygiene |
How to interrupt: Control of Portal to Exit | Healthcare personal must practice standard precautions |
How to interrupt: Prevent of Transmission | Proper hand washing |
How to interrupt: Protect Portal of Entry | Healthcare workers must make sure parts of entry sure not subjected to pathogens |
How to interrupt: Recognition of Susceptible Host | Health professionals must recognize and protect high-risk patients |
