Pathogen

A pathogen is any biological agent — including bacteria, viruses, fungi, protozoa and prions — that can cause infection or illness in a host. Pathogens vary widely in how they spread, how long they survive on surfaces and how susceptible they are to different disinfectants and contact times.

Disinfection protocols are designed around the pathogens of concern in a given setting. Understanding which pathogens are relevant helps organisations choose the right disinfectant chemistry, concentration and contact time.

Healthcare, food production, veterinary care and water treatment settings all target specific pathogen groups when validating cleaning and disinfection programmes.
