Impetigo is a contagious skin infection caused by bacteria. It is most common in children, but can occur in people of all ages. The bacteria that cause impetigo are usually found on the skin, but they can enter the body through a break in the skin, such as a cut or scratch. Impetigo is usually caused by either staphylococcal or streptococcal bacteria and presents as small blisters or crusty lesions on the skin.
Impetigo typically begins as small, red spots that develop into fluid-filled blisters. These blisters rupture and form a yellow or honey-colored crust, which is a characteristic feature of impetigo. The infection usually appears around the nose, mouth, and other areas of the face but can spread to other parts of the body. Impetigo may cause itching and discomfort, and in some cases, it can lead to more severe complications, such as cellulitis or kidney inflammation, if left untreated.
Impetigo is highly contagious and spreads easily through direct skin-to-skin contact, contaminated objects, or even through the air via respiratory droplets. The bacteria can enter the skin through cuts, insect bites, or other minor injuries, making it essential for beauty professionals and estheticians to be vigilant about preventing the spread of impetigo in their work environment.
There are two main types of impetigo:
- Nonbullous impetigo: This is the most common type of impetigo. It starts as a small red bump or blister that oozes fluid and crusts over.
- Bullous impetigo: This type of impetigo is less common. It starts as a large blister that is filled with fluid. The blister may burst, leaving a raw, red area of skin.
Impetigo is usually treated with antibiotics. The antibiotics may be taken by mouth or applied to the skin. It is important to finish all of the antibiotics, even if the sores start to look better. If the antibiotics are not taken completely, the infection may come back.
Impetigo typically falls outside the scope of practice of skincare and beauty specialists, and it is advisable to consult a qualified healthcare professional for its treatment. As a highly contagious condition, skincare experts encountering a case of impetigo should exercise extreme caution to prevent transmission to their families or clients.
