There’s another type of rash that is not associated with the immune system. Instead, it is caused by delayed clotting and repair of tissues. The body continuously undergoes microscopic injuries, and clotting contributes to healing them before the blood starts leaking to the interstitial tissue. Hemorrhagic skin rash appears when blood clotting is not fast enough. We will often see red spots or red areas in the skin, and they are sometimes associated with a traumatic event. When not associated with trauma, hemorrhagic manifestations in adults are by far the more worrying type of rash.
