Typhus Symptoms & Signs
While there are many different types, rashes may basically be divided into two types: infectious or noninfectious.
Noninfectious rashes include eczema, contact dermatitis, psoriasis, seborrheic dermatitis, drug eruptions, rosacea, hives (urticaria), dry skin (xerosis), and allergic dermatitis. Many noninfectious rashes are typically treated with corticosteroid creams and/or pills. Even a noncontagious, noninfectious rash can cause discomfort and anxiety.
Infection-associated rashes, such as ringworm (tinea), impetigo, Staphylococcus, scabies, herpes, chickenpox, and shingles, are treated by treating the underlying cause. Infectious agents that can cause a rash include viruses, bacteria, fungi, and parasites.
