Objectives We will discuss on State the concept of Infection prevention and control State the definition of Infection Prevention and control Outline the importance of IPC Describe the disease transmission cycle State the scope of IPC Explain health care associated infections
Definition of IPC Infection prevention and control is scientific approach and practice designed to prevent harm caused by infection to patients and healthcare workers. It focuses on evidence-based practices and procedures that can prevent or reduce the risk of transmission of microorganisms

To prevent the spread of infections from patient-to-patient patients to health care providers health care providers to patients health care providers to health care providers and to visitors and others in the health care environment
Healthcare associated infection (HCAI) It is the infection acquired by patient after 48 hours of hospitalization, or during the course of receiving treatment within a healthcare settings and was not present or incubating at the time of admission. Associated with the devices used in medical procedures such as ventilators or catheters. Formerly known as N osocomial infection.
