Impetigo Contagiosa, also known as impetigo, is a highly contagious skin infection caused by bacteria. It is most commonly seen in children, though adults can also be affected. Symptoms of impetigo contagiosa include red, itchy sores that form on the arms, legs, and face. These sores are filled with fluid and may leak pus or blood. They eventually form a yellowish crust, which is a sign of the infection.
The most common cause of impetigo contagiosa is the bacteria Streptococcus pyogenes, but it can also be caused by Staphylococcus aureus. The infection is spread through direct contact with an infected person, or by touching an infected object, such as a towel or toy. People with weakened immune systems, such as those with HIV or cancer, are more likely to develop impetigo contagiosa.
Treatment for impetigo contagiosa typically involves antibiotics in the form of a pill or cream. The infection should clear up in 7 to 10 days, but if it does not, a doctor may prescribe a stronger antibiotic or a steroid cream. In some cases, impetigo contagiosa can cause serious complications, such as cellulitis, abscesses, and scarring.
It is important to prevent the spread of impetigo contagiosa by washing hands regularly, keeping wounds clean and covered with sterile bandages, and avoiding contact with people who have the infection. If someone in your household has impetigo contagiosa, take extra precautions to keep the infection from spreading.
