![]() ![]() ![]() Method of transmission There are three mechanismsġ. Before an infection can establish itself in a host, the microorganisms must leave the reservoir.Ĥ.Reservoir There are many reservoirs, or sources of microorganisms, common sources are other humans, the client's, plants, animals, or general environment. Major sites for these infections are the respiratory and urinary tracts, the bloodstream, and wounds.įactors that contribute to nosocomial infection risks are invasive procedures, medical therapies, the existence of a large number of susceptible persons, inappropriate use of antibiotics, and insufficient hand washing after client contact and after contact with body substances.ġ.Etiologic agent The any microorganism is capable of producing an infectious process depends on the number of microorganisms present.Ģ. The incidence of nosocomial infections is significant. Nosocomial infections can either develop during a client's stay in a facility or manifest after discharge. classified as infections that are associated with the delivery of health care services in a health care facility.A chronic infection may occur slowly, over a very long period, and may last months or years. When bacteremia results in systemic infection, it is referred to as septicemia.Īcute infections generally appear suddenly or last a short time.When a culture of the person's blood reveals microorganisms, the condition is called bacteremia. If the microorganisms spread and damage different parts of the body, it is a systemic infection.ParasitesThey include protozoa such as the that causes malaria.Ī local infection is limited to the specific part of the body where the microorganisms remain. Viruses(causes the common cold) hepatitis, herpes, and human immunodeficiency virus. Bacteriacan live and be transported through air, water, food, soil, body tissues and fluids, and inanimate objects. Types of microorganisms causing infectionsġ. Sepsis is the state of infection and can take many forms, including septic shock. Surgical asepsis is used for all procedures involving the sterile areas of the body. Surgical asepsis or sterile Technique, refers to keep an area or object free of all microorganism, it includes practices that destroy all microorganisms and spores. In medical asepsis, objects are referred to as clean, which means the absence of almost all microorganisms, or dirty (soiled, contaminated, which means likely to have microorganisms, some of which may be capable of causing infection.Ģ. Medical asepsis Includes all practicesintended to confine a specific microorganism to a specific area, limiting the number, growth, and transmission of microorganisms. ![]() There are two basic types of asepsis Medical & Surgical asepsis.ġ. To decrease the possibility of transferring microorganisms from one place to another, asepsis is used. Identify measures that break each link in the chin of infection.Īsepsis Asepsis is the freedom from disease-causing microorganisms.Identify factors influencing a microorganism's capability to produce an infectious process.Identify risks for nosocomial infections.
