A community infection is an infection occurring outside a health facility, as opposed to a nosocomial infection. This type of infection is the most common. The causative organisms can be viruses, bacteria, fungi or parasites. These germs are characterized by a relatively low probability of resistance, compared with those of nosocomial infections. This is particularly the case with regard to bacterial resistance.
