Final answer:
A skin infection called furuncles is commonly known as boils, caused primarily by Staphylococcus bacteria, and good skin care can help in prevention.
Step-by-step explanation:
The skin infection referred to as furuncles is more commonly known as boils. Boils are essentially infections that go deeper into the skin and are mostly caused by Staphylococcus bacteria. They can be common among teenagers and young adults, particularly those in contact sports, those with compromised immune systems, or living in closely packed environments. Maintaining good skin care and hygiene can prevent furuncles from getting worse, but medical attention is required if they spread or are accompanied by systemic symptoms like fever.
