7. INCIDENCE
Tinea Capitis Infection may infect individuals of
any age, gender, race, or ethnicity; if factors for
fungus growth on the head, are conducive
The condition rarely affects adults, but it is most
commonly seen in young children (between 5 and
10 years)
It is also generally seen with a higher incidence in
boys, than girls (in a 5:1 ratio)
8. RISK FACTORS
Children, who are exposed to other infected
children, particularly at schools, daycare
centers for children, theme parks etc.
Individuals residing in overcrowded
neighborhoods (that are warm and humid)
Children with sweaty (wet) scalp conditions
Those having superficial (on the surface) and
minor head injuries
The potential risk factors for Tinea Capitis
9. Sharing items like combs, brushes or hats with
individuals having the fungal condition
If the individual has a weak immune system or
diabetes, there is a greater susceptibility to fungal
infections,
Those, who were infected with fungal infections in
the past, have an elevated risk
Do not bathe or wash your hair often
