What Causes Guttate Psoriasis?
Guttate psoriasis often erupts quite suddenly. It may be triggered by an injury or infection. In fact it is often associated with strep throat, a bacterial infection of the throat. Other illnesses that may trigger an attack of guttate psoriasis include tonsillitis, a common cold, or chicken pox. Vaccinations, physical trauma, psychological stress, and antimalarial drugs have also been associated with the onset of guttate psoriasis.
