Dermatological infections are skin conditions caused by various pathogens, including bacteria, viruses, fungi, and parasites. Common examples include bacterial infections like impetigo, viral infections such as herpes simplex, and fungal infections like athlete's foot. These infections can lead to symptoms like redness, swelling, itching, and sometimes pus formation. Treatment for dermatological infections often involves topical or oral medications, depending on the severity and type of infection. Maintaining good hygiene and avoiding contact with infected individuals can help prevent the spread of these conditions. In some cases, a healthcare professional may need to perform a skin culture to identify the specific pathogen involved.
