Listeria monocytogenes Infection (cont.)
IN THIS ARTICLE
Most individuals who ingest food products contaminated with Listeria monocytogenes will experience no symptoms (asymptomatic) and have an excellent prognosis.
For high-risk individuals (and the rare healthy individual) who develop listeriosis, the prognosis depends on many factors, such as the underlying state of health when infected and the severity of illness upon presentation to a health care professional. The prompt recognition and diagnosis of the illness is also important, as the timely initiation of intravenous antibiotics can also affect the prognosis and outcome. Nonetheless, even with prompt diagnosis and treatment, some cases of listeriosis will be fatal. The overall mortality rate for clinical infections with Listeria monocytogenes is 20%-30%.
