California State Board Barber Practice Exam

Ringworm is a skin infection that is caused by fungi and is highly contagious. This infection can easily spread from person to person or through contact with infected objects, such as towels or clothes. Because it is contagious, it can be dangerous if not treated properly as it can easily spread and lead to more serious complications. Options A and B, which suggest the infection is non-contagious or non-infectious, are incorrect as ringworm is indeed highly contagious. Option D, benign, is also incorrect as although ringworm is not life-threatening, it can still cause discomfort and need to be treated.
