What Is The Most Common Nail Infection?

Onychomycosis is a common fungal infection affecting the nail plate and the bed. Its symptoms include deformed and discolored nails. Treatment is usually oral terbinafine. About 10% of the population is affected by this infection. There are several other types of nail infections, and they all cause pain and discomfort. Some are fungal, and some are dermatophytes. To understand the differences between each type, let’s define the terms. If you are experiencing these infections, you should visit the best chiropodist near me.

Onychomycosis:

There are several different types of onychomycosis. The most common form is distal subungual onychomycosis caused by a dermatophyte fungus. It usually starts in the nail bed and spreads from the edges to the center. In some cases, the disease can cause the nail to crumble.

Dermatophyte infections cause 60 to 80% of the infections. Nondermatophytemoulds cause the other types. The fungus may also cause a disease known as candidal onychomycosis in immune-compromised patients. Onychomycosis can also increase the risk of lower extremity cellulitis.

Dermatophytosis:

Dermatophysis is an infection of the nails caused by fungi. The fungi involved in the infection include epidermophyton, trichophytonrubrum, and microsporum. These fungi cause 90% of all cases of onychomycosis in the toenails and fingernails.

In general, dermatophyte nail infection presents in the form of discoloration of the nail plate, with the toenail being more commonly affected than fingernails. Symptoms typically begin in the proximal nail fold and extend to the lateral margins. The periungual area becomes swollen and erythematous, and the nail is discolored or thickened. In severe cases, the nail may become detached from the nail bed.

Staphylococcus aureus:

Paronychia is an infection of the skin surrounding the nail, usually caused by Staphylococcus aureus. The condition is typically characterized by red, erythematous inflammation, pain, and tenderness in the nail folds. In severe cases, an abscess may be present. In the early stages of infection, treatment includes an incision and drainage. In severe cases, antibiotics may be necessary.

Although the skin is usually a barrier against infection, skin injuries and viral infections can allow S. aureus to access underlying tissue or even the bloodstream. This bacteria is particularly harmful to people with weakened immune systems and those who use invasive medical devices such as intravenous catheters or stents. Methicillin-resistant strains of S. aureus are particularly dangerous because they can cause life-threatening infections.
