Thank you. That is very interesting, not only because it is new to me, and guessing to most others here. Also because it goes with my decision, couple of days ago, to ask the dr. to take a swab, skin sample whatever to determine exactly, if possible, which virus, or whatever, i have. As mentioned before, as a kid i had the worst case of athletes foot my dr. dad said he had ever seen. Don't seem to have fluid filled (but could be) and definitely have "red raised" bumps. Iodine fixed that by puncturing to release the fluid then applying iodine.
An id reaction, also known as autoeczematization, is a secondary skin eruption that occurs at a site distant from an initial inflammatory or infectious skin condition. It's essentially the body's immune system reacting to a primary skin issue by producing a new rash elsewhere on the body.
Here's a more detailed explanation:
What causes it?
Id reactions are often triggered by fungal infections (like tinea pedis or athlete's foot) or bacterial infections.
They can also be caused by other inflammatory skin conditions, such as scabies, eczema, or contact dermatitis. In some cases, they can be associated with conditions like molluscum contagiosum, pediculosis capitis, or even arthropod bites.
How does it look?
The rash associated with an id reaction can vary, but it often includes:
Small, fluid-filled blisters or bumps. Red, raised patches. Eczematous (itchy, inflamed, and possibly scaly) areas. Sometimes, the rash may resemble target-like lesions or hives.
It can appear on various parts of the body, not just near the initial infection site.
What happens?
The primary skin condition triggers an immune response in the body. This immune response leads to the release of substances that cause inflammation and the development of a new rash at a different location. This new rash is essentially the body's immune system reacting to the primary condition.
Important points:
The rash associated with an id reaction is not contagious.
It won't show signs of the original infection (e.g., fungal spores if it's related to a fungal infection).
Treating the underlying condition (the initial infection or inflammation) is the key to resolving the id reaction.
"ID reaction" in the context of tularemia refers to an immune-mediated skin reaction that can occur as a secondary response to the infection, particularly in cases of orf. It's characterized by a generalized, symmetrical rash of small, raised bumps (papules) or sometimes blisters (vesicles), often remote from the primary tularemia lesion. This rash can be intensely itchy and can occur in response to various infections, including those caused by the tularemia bacteria (Francisella tularensis) or the orf virus (a parapoxvirus).

"You might want to Google an "id reaction " it can be resultant from bacterial or viral situations. I only know about it from having contracted tularemia as a kid from rabbits.
Thanks heaps, always good to learn something totally new about present dangers. To be "woke" more like in the original, real cultural sense, i mean.
Hope the dr. gp is familiar with "id reaction." They can't be expected to be up on everything.
