Anything that can affect the immune system can affect psoriasis. In particular, streptococcus infection (strep throat) is associated with guttate psoriasis. Strep throat often is associated with the first onset of guttate psoriasis in children. You may experience a flare-up following an earache, bronchitis, tonsillitis or a respiratory infection, too.
It's not unusual for someone to have an active psoriasis flare with no strep throat symptoms. Talk with your doctor about getting a strep throat test if your psoriasis flares.
