Rash-associated diseases are infectious diseases that present with skin manifestations. Measles, rubella, chickenpox, shingles, hand-foot-mouth disease, and various viral exanthems are included in this group. The character, distribution of the rash, and accompanying findings are guiding in diagnosis.
Differential diagnosis of these diseases is important because they can be confused with drug reactions, autoimmune diseases, and other dermatological conditions. Careful clinical evaluation and laboratory tests when necessary help reach a diagnosis.
Raising awareness about vaccine-preventable diseases and vaccination recommendations form an important component of this field. Rash infections may have a more severe course in immunocompromised patients.
