Silent celebration
In medicine, silent celebration is an immune response of the body in the context of a symptom-free (asymptomatic, inapparent or silent) infection with a pathogen .
Mark
In immunology , this expression means that an organism or a person becomes immune to the pathogen of an infectious disease after a silent - also called inapparent or asymptomatic - infection . The pathogens in the body are completely killed by the immune system without this person having ever been immunized against this type of pathogen and any signs of illness being observed after the infection. After a silent celebration, just like after a vaccination , this person can no longer fall ill with a renewed infection with the same type of pathogen, since protective antibodies are left behind from the silent argument between pathogen and host . Such a noisy or signless immunization is usually not noticed by the person concerned. However, a slight indisposition, exhaustion or tiredness may occur, each of which is not assigned any disease value.
Occurrence
In humans, there is often a silent celebration in the event of infections with pathogens that are already very well adapted to humans as their reservoir host. As a result, only with pathogens that have been adapted in this way does a healthy and strong immune system have the chance to successfully fight these pathogens and protect the organism from further infections of the same pathogen without the person affected developing any symptoms.
Word origin
The noun Feiung is derived from the transitive verb feien , which means something like "protect" (to be immune to something). It comes from the mhd. Word Fei (e) for a " fairy ", a goddess of fate; Feiung originally means "protection given by fate".
