ABSTRACT
The human nail, chemically similar to horn and hoof, is not essential to the survival of Homo sapiens, but it has many important functions that are crucial for the efficient use of the hands and feet. It is also a prime route for the transmission of organisms (both macro-and microscopic), toxins, irritants and allergens. Maintaining nail cleanliness is essential to many aspects of health. Nails of nurses may be the vehicle of transmission of severe and fatal infections, especially in neonatal or intensive care units. Nurses should keep their nails short and avoid wearing artificial nails and nail varnishes.
