According to global health data, fungal skin diseases were the single most prevalent skin condition worldwide in 2017, affecting roughly one in ten people, and more than <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC11686433\/\" target=\"_blank\" rel=\"noreferrer noopener\">1.65 billion people<\/a> were living with some form of fungal skin disease as of 2019.<sup>2<\/sup>\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A fungal infection develops when microscopic fungi\u2014organisms that thrive in warm, moist environments\u2014multiply on the skin, hair, or nails faster than the body&#8217;s immune system can clear them.

It is a fungal skin infection <a href=\"https:\/\/www.cdc.gov\/ringworm\/hcp\/clinical-overview\/index.html\" target=\"_blank\" rel=\"noreferrer noopener\">caused by dermatophytes<\/a>, a group of fungi that feed on keratin, the protein found in skin, hair, and nails.<sup>4<\/sup>\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ringworm typically appears as a red or pink, scaly patch with a raised, ring-like border and a clearer center, though its appearance can vary depending on skin tone. It is contagious and may spread through direct skin contact, shared clothing or towels, or contact with an infected animal.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Jock Itch (Tinea Cruris)<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Jock itch is caused by the <a href=\"https:\/\/my.clevelandclinic.org\/health\/diseases\/22141-jock-itch-tinea-cruris\" target=\"_blank\" rel=\"noreferrer noopener\">same family of fungi<\/a> responsible for athlete&#8217;s foot and ringworm, but it affects the groin, inner thighs, and buttocks.<sup>5<\/sup> It tends to develop in warm, humid conditions and is more common in people who sweat heavily or wear tight-fitting clothing. Typical signs of jock itch include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A red or reddish-brown rash with a defined border<\/li>\n\n\n\n<li>Itching or burning that worsens with activity<\/li>\n\n\n\n<li>Flaking, peeling, or cracking skin in the groin folds<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Yeast Infections of the Skin (Cutaneous Candidiasis)<\/strong><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Not all fungal infections are caused by dermatophytes.

However, patients should generally schedule an appointment with a dermatologist if:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The rash does not improve after a few weeks of over-the-counter treatment<\/li>\n\n\n\n<li>The infection is widespread, painful, or affects the scalp or nails<\/li>\n\n\n\n<li>Symptoms keep returning after treatment appears to work<\/li>\n\n\n\n<li>There are signs of a secondary bacterial infection, such as increasing redness, warmth, swelling, or drainage<\/li>\n\n\n\n<li>The diagnosis is uncertain, since several skin conditions can resemble a fungal skin infection<a name=\"Schedule An Appointment Today\"><\/a><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.robertmrogersmd.com\/about\/\">Trained dermatologists<\/a> have access to prescription-strength topical and oral antifungal medications not available over the counter, along with tools such as dermoscopy for cases where the diagnosis is not straightforward.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Schedule An Appointment Today<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Fungal skin infections vary widely in appearance, location, and severity, but they share several common threads: the fungi involved thrive in warm, moist environments, many strains are contagious, and accurate diagnosis is the foundation of effective treatment. Patients who notice a rash that will not clear, keeps returning, or affects the nails or scalp should not rely on trial and error with over-the-counter products alone, but rather on the expertise of a trained dermatologist.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you are searching for a dermatologist in Greenville to evaluate a stubborn rash or nail changes that you suspect may be a fungal infection, do not delay. The providers at Rogers Dermatology offer in-office diagnostic testing, including skin scrapings and, when appropriate, fungal cultures, to help confirm a diagnosis before starting treatment.<a name=\"FAQ\"><\/a> You can expect a thorough evaluation and a treatment plan suited to the specific type of fungus involved. <a href=\"https:\/\/www.robertmrogersmd.com\/contact\/\">Contact us today<\/a> to schedule an appointment.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading has-vivid-cyan-blue-color has-text-color has-link-color wp-elements-1\">Is a fungal skin infection the same as a bacterial infection?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">No, fungal and bacterial skin infections can look similar but generally require different treatments. A dermatologist can help determine the underlying cause through a physical examination and, when needed, laboratory testing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-vivid-cyan-blue-color has-text-color has-link-color wp-elements-2\">Are fungal skin infections contagious?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Many are. Ringworm, athlete&#8217;s foot, and jock itch may spread through direct skin contact, shared personal items such as towels or razors, and contact with contaminated surfaces like locker room floors. Tinea versicolor and candidiasis are generally considered less contagious, since the fungi involved already live naturally on most people&#8217;s skin.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-vivid-cyan-blue-color has-text-color has-link-color wp-elements-3\">Can a fungal infection go away on its own?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Some mild cases may improve with consistent hygiene and over-the-counter antifungal treatment, but fungal infections do not typically resolve completely without treatment and can persist or worsen if left unaddressed, particularly on the nails or scalp.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-vivid-cyan-blue-color has-text-color has-link-color wp-elements-4\">How long does it take to treat a fungal skin infection?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Treatment duration depends on the type and severity of the infection. <a name=\"References\"><\/a>Many skin infections tend to improve within a few weeks of consistent topical treatment, while nail infections often require several months of treatment due to the slow rate of nail growth.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">References<\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Deng Li, Siqi Fan, Haochen Zhao, et al., \u201cWorldwide trends and future projections of fungal skin disease burden: a comprehensive analysis from the Global Burden of Diseases study 2021,\u201d <em>Frontiers in Public Health<\/em>, June 2025, <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC12174046\/\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC12174046\/<\/a>.\u00a0<\/li>\n\n\n\n<li>Hongping Wang, Fengjun Sun, Changquan Wang, et al., \u201cA systematic analysis of the global, regional, and national burden of fungal skin diseases from 1990 to 2021,\u201d <em>Frontiers in Epidemiology<\/em>, December 2024, <a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC11686433\/\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC11686433\/<\/a>.\u00a0<\/li>\n\n\n\n<li>\u201cAthlete\u2019s Foot,\u201d Mayo Clinic, January 2026, <a href=\"https:\/\/www.mayoclinic.org\/diseases-conditions\/athletes-foot\/symptoms-causes\/syc-20353841\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/www.mayoclinic.org\/diseases-conditions\/athletes-foot\/symptoms-causes\/syc-20353841<\/a>.\u00a0<\/li>\n\n\n\n<li>\u201cRingworm,\u201d U.S. Centers for Disease Control and Prevention, July 2024, <a href=\"https:\/\/www.cdc.gov\/ringworm\/hcp\/clinical-overview\/index.html\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/www.cdc.gov\/ringworm\/hcp\/clinical-overview\/index.html<\/a>.\u00a0<\/li>\n\n\n\n<li>\u201cJock Itch (Tinea Cruris),\u201d Cleveland Clinic, December 2021, <a href=\"https:\/\/my.clevelandclinic.org\/health\/diseases\/22141-jock-itch-tinea-cruris\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/my.clevelandclinic.org\/health\/diseases\/22141-jock-itch-tinea-cruris<\/a>.\u00a0<\/li>\n\n\n\n<li>E.H.
