Answer

P ovale is present on 90-100% of the surface of healthy skin; higher numbers of the yeast are present on the chest and back. Certain climates influence the percentage of people with P ovale and the number of people with Pityrosporum folliculitis. People living in warm and humid climates have a higher incidence of Pityrosporum folliculitis. One clinic in the Philippines documented that 16% of all patient visits were a result of Pityrosporum folliculitis. [16] A 2008 report from China cites that 1.5% off all dermatology patients were diagnosed with Pityrosporum folliculitis, most of them healthy, middle-aged males. [17]
