kryssinfeksjon

Kryssinfeksjon, also known as cross-infection, refers to the unintended transfer of pathogenic microorganisms from one person or place to another. This can occur directly, such as through physical contact between an infected individual and a susceptible one, or indirectly, via contaminated surfaces, objects, or even airborne particles. Healthcare settings are particularly susceptible to kryssinfeksjon, where patients with weakened immune systems or existing infections can be exposed to new pathogens from other patients, staff, or medical equipment.

Preventing kryssinfeksjon relies on stringent hygiene practices. Handwashing is a cornerstone of infection control, as is the proper cleaning and sterilization of medical instruments and equipment. Environmental disinfection of surfaces and isolation of infectious individuals also play crucial roles. Understanding the routes of transmission is essential for implementing effective control measures. Common examples include the spread of bacteria like Staphylococcus aureus or viruses such as influenza. Public health initiatives often focus on educating the public about basic hygiene to mitigate the spread of infections in the wider community.
