Yellow sores usually heal completely in about two weeks after regular treatment. Yellow sores, also known as impetigo, are mainly caused by bacterial infections, with common causative agents including Staphylococcus aureus and Streptococcus hemolyticus type B. Triggering factors include hot and humid environments, low immunity, and impaired skin barrier function. The most common type is common impetigo, which is usually treated with topical antibiotics, such as mupirocin ointment and fusidic acid cream, etc. In severe cases, sensitive antibiotics can be used systematically. After a regular course of antibiotic treatment, most patients are usually completely cured within two weeks. Yellow water sores are highly contagious and tend to occur in children. Therefore, when yellow water sores appear, it is important to avoid crowds, especially in daycare centers and kindergartens, etc. Patients should be treated actively to avoid scratching and spreading the disease themselves, which will help them heal as soon as possible.
