What is Tinea Capitis?
One of a number of fungal skin infections that commonly affects children, Tinea Capitas is the name of a condition also known as scalp ringworm.
During this condition, the scalp becomes infected with dermatophyte fungus. This type of fungus grows on surfaces such as skin, hair and nails, and causes ringworm and other diseases. Tinea Capitas can be caused by a number of zoophilic fungi, often originated from animals such as cats, cattle, pigs and horses.
What are the symptoms of Tinea Capitis?
A few of the symptoms associated with this type of infection include scaling that can dandruff-like residue, and black dots appearing on the scalp where the hair has been scaled away.
A kerion may form, which is an abscess caused by fungal skin infections. Favus is name given to tinea capitis in it’s most severe stage, and is characterized by yellow crusts appearing in the hair. If left untreated, both of these symptoms can result in permanent scarring and hair loss/bald spots.
What causes Tinea Capitis?
Fungal skin infections often occur as a result of people living in close proximity to each other, as the fungus can easily spread from person to person, and tinea capitis is no different. Furthermore, fungus can live on things like clothing, towels, sheets and other surfaces for months at a time, meaning people can become infected long after the initial contamination took place. When Tinea Capitis is caused by zoophilic infection, this is due to direct contact with an infected animal rather than an item.
Who is at risk of Tinea Capitis?
Children are at highest risk of the condition, as it most prevalently affects children aged between three and seven, infecting boys more commonly than girls. Adults living in crowded spaces may come into contact with the trichophyton tonsurans fungus and, while rare, the infection may develop.
How does a Dermatologist diagnose Tinea Capitis?
Symptoms such as scarring, scaling and bald patches may lead a dermatologist to suspect Tinea Capitis.
To confirm a diagnosis, a dermatologist may scape skin from the affected area along with hair removed at the roots, and examine them under a microscope. In more serious cases, a skin biopsy may be performed.
How does a Dermatologist treat Tinea Capitis?
Antifungal medicines are prescribed to treat Tinea Capitis, with successful treatment normally curing the condition with four to six weeks. If a kerion is present and it has become infected and swollen, a dermatologist may also prescribe further medicines to alleviate pain and reduce the inflammation.
