Associate – Infection Prevention And Control (a-IPC) Practice Exam

The key point is that Mycobacterium marinum causes a localized skin infection acquired from aquatic environments and is not spread from person to person. Because of this, standard infection prevention measures apply to the wound itself, but there is no need for isolation precautions aimed at preventing transmission to others, such as airborne or contact precautions, and no routine public health reporting or contact tracing is required in typical cases. A positive culture with acid-fast bacilli confirms the presence of a mycobacterial infection, but it does not change the fact that M. marinum is not considered contagious between people. Therefore, after confirming the diagnosis, the follow-up is focused on appropriate wound care and management of the infection rather than implementing isolation or reporting steps. If the patient develops disseminated disease, has extensive infection, or is immunocompromised, different actions may be needed, but in standard wound infections from aquatic exposure, no further infection-control follow-up is usually necessary.
