Epidemiology of dermatophyte infections among school children in Menoufia Governorate, Egypt

Abstract

Most superficial mycotic infections of human skin are due to dermatophytes. Children are frequently affected due to different predisposing factors, particularly overcrowding in classrooms. This study aimed to estimate the prevalence of dermatophytes infections and their related risk factors among school children in Menoufia Governorate, Egypt. Six public primary and preparatory schools were randomly selected and their pupils (n = 3464) were asked to complete a predesigned questionnaire covering both personal data and suspected risk factors for superficial dermatophyte infections. The children were also examined for dermatological diseases. Any suspected lesions were biopsied for mycological examination. The prevalence of clinically suspected dermatophytes infections was 1.41%, whereas the prevalence of culture confirmed cases was 0.98%. The most common clinical type was tinea capitis with a prevalence of 1.01%. Microsporum canis was the only isolated organism from the suspicious lesions with a 69.4% positivity rate. A higher prevalence was observed among boys, low socio-economic pupils and those with a family history of dermatophyte infections. Pet contact and sharing towels and caps among pupils were significant risk factors. Dermatophyte infection is still prevalent among basic school pupils. Fortunately, it is related to preventable risk factors. We recommend regular screening and use of educational health programmes for kids to control it.

Species distribution and epidemiological characteristics of superficial fungal infections in Southeastern Serbia

“…Excessive foot sweating (hyperhidrosis) can also be predisposing condition for the development of SFI, and it was confirmed by our results as well. Another risk factor, established in patients with t. corporis, is keeping pets, also found in a new study involving Egyptian children …”

Analysis on the pathogenic fungi in patients with superficial mycosis in the Northeastern China during 10 years

“…Superficial mycosis is a common disease in dermatology, which is characterized by common occurrence, multiple occurrence and recurrence, with a prevalence rate of about 20% worldwide (14,15). In recent years, the incidence rate of individual superficial mycosis has increased year by year, and the types of pathogenic fungi are also diversified (16). In 5,743 cases of superficial mycosis collected in this subject, tinea pedis was the most common disease, followed by tinea cruris and onychomycosis.…”

Clinico-mycological profile of tinea capitis and its comparative response to griseofulvin versus terbinafine

“…Our findings revealed sport (37.7%) and contact with an infected animal (20.3%) as the most common risk factors for TC. These factors, along with other factors, such as high-risk jobs, use of public swimming pool, and nonpractice of personal hygiene (e.g., sharing hairbrushes, hat, headrest, and bed) are effective not only in the induction of TC but also in the determination of the disease clinical type and location of lesions [22, 24, 25].…”
