infektionstyp

Infektionstyp is a German term meaning "type of infection" and is used to categorize infections according to their cause, location, transmission, course, and host factors. Classifications help clinicians, microbiologists, and public health professionals communicate about disease etiology, prognosis, and control measures.

Common classification schemes include pathogen-based types (bacterial, viral, fungal, parasitic), anatomical site (respiratory, gastrointestinal, urinary, skin and soft tissue, central nervous system), transmission route (contact, droplet, airborne, vector-borne, food- or waterborne), and temporal pattern (acute, chronic, latent, recurrent). Other distinctions recognize community-acquired versus healthcare-associated infections and primary versus opportunistic infections based on host immunity.

Examples illustrate the utility of the concept: influenza is an acute viral respiratory infektionstyp transmitted by droplets, urinary tract infection is typically a localized bacterial infektionstyp, and tuberculosis is a chronic bacterial infektionstyp that may be latent. Severity-based descriptors (mild, severe, systemic, life-threatening) further guide management priorities.

Determination of an infektionstyp relies on history, physical examination, laboratory testing, imaging, and microbiological identification. Classification informs treatment choices, infection control precautions, vaccination strategies, and public health responses. Understanding different infektionstypen also supports surveillance, outbreak investigation, and antimicrobial stewardship.
