Bacterial infections occur when the bacteria that already exist naturally in the skin multiply in excess or when there is infection by other different bacteria.
Locations of the skin such as: nostrils, ears, navel, genitals, armpits, under the fingernails, present larger amounts of bacteria and should be particularly careful. A common infection is impetigo, particularly in children. Another is the boil, which can be repeated many times in the same person and in others nearby. In this case, in addition to treating the patient, it is important to treat areas of the skin that naturally have more bacteria, in people who live in the same house or who have intimate physical contact with the affected patient, as they may be asymptomatic carriers of bacteria and function As the focus of infection transmission.
