3.4.5 Fingernail and toenail hygiene (nail care)
A nail is hard tissue that constantly grows. Long fingernails tend to accumulate or trap dirt on the underside. The dirt could be as a result of defecation or touching infected and contaminated surfaces. Keeping nails trimmed and in good shape weekly is important in maintaining good health. Clip nails short along their shape but do not cut them so close that it damages the skin. Razor blades and fingernail cutters or scissors are used to cut nails. Nail cutters should not be shared with others.
Why is it inadvisable to share nail cutters?
Because some diseases, such as fungal infections, can be transmitted easily from person to person in this way.
