What is Nail Infection?
A nail infection is an infection of the skin beneath a fingernail or toenail. Common signs and symptoms of nail infection include swelling, redness, pain, and thickening or discoloration of the nail. A nail infection is usually caused by a bacteria or fungus, and can be treated with oral medications or topical creams. It is important to see a doctor if you suspect you have a nail infection, as it can spread to other parts of the body if it is not treated promptly.
Types of Nail Infections
Nail infections can be caused by a variety of bacteria and fungi. The most common type of nail infection is onychomycosis, which is caused by a fungus. Fungal nail infections are more common in toenails than fingernails, and can cause the nail to become yellow, thick, and brittle. Other types of nail infections include bacterial infections, such as paronychia, which can cause the skin around the nails to become red and swollen.
Causes of Nail Infections
Nail infections are most commonly caused by bacteria and fungi, although they can also be caused by other organisms or by physical trauma to the nail. Fungal nail infections are usually caused by dermatophytes, a type of fungus that is found in warm, moist environments such as shower stalls. Bacterial infections are usually caused by staphylococcus or streptococcus bacteria, which are found in warm, moist environments as well.
Risk Factors for Nail Infections
Certain risk factors increase your chances of having a nail infection. These include:
- Poor hygiene: Not washing your hands and feet regularly can increase your risk of infection.
- Too much moisture: Wearing shoes and socks that keep feet moist can increase your risk of infection.
- A minor skin injury: A scratch or cut in the skin around the nail can provide an entry point for bacteria and fungi.
- A weakened immune system: Having a weakened immune system can make it harder for your body to fight off infections.
- Frequent manicures and pedicures: Having frequent manicures and pedicures can increase your risk of getting a nail infection.
Prevention of Nail Infections

- Wash your hands and feet regularly with soap and water.
- Keep your feet dry by wearing breathable shoes and socks.
- Avoid going barefoot in public areas such as swimming pools and locker rooms.
