Nail infections

Nail infection, as the name suggests, is an infection affecting the fingernails or toenails. It can be caused by the growth of bacteria, fungus or virus in these areas. Fungal nail infection is more commonly seen to affect toenails, while bacterial nail infection is more likely to occur following an injury to the surrounding skin.

Nail infection, particularly fungal nail infection or onychomycosis, is commonly seen. It is estimated that about 10% of the general population, 20% of the population older than 60 years, and 50% of the population older than 70 years suffer from nail infection of any one or the other type.

Nail infection is common in the elderly population and those who suffer from immunocompromised conditions such as HIV (human immunodeficiency virus)infection. The risk of nail infection increases if the feet or hands are constantly exposed to moisture and proper hygiene is not maintained.

The symptoms of nail infection range from whitish spots or patchy discoloration of the nails to changes in the shape of the nail and the nails turning brittle or crumbly. Treatment consists of oral and topical antibacterial or antifungal agents. Surgery may be required in severe cases.
