The most common type of staphylococcal infection is a localized purulent infection of the skin. This type of infection typically manifests as abscesses, boils, or other types of localized pus formations due to the presence of staphylococcus bacteria, particularly Staphylococcus aureus. These infections arise primarily from the bacteria invading hair follicles or skin damaged through cuts or abrasions.

Localized infections are widespread because of the bacteria’s ability to colonize the skin easily and the commonality of minor skin injuries that can allow these bacteria to enter and infect the tissue. This contrasts with more diffuse infections, which tend to be more severe and can affect larger areas of the skin, and are less common compared to localized infections. Additionally, conditions like staphylococcal osteomyelitis and impetigo are comparatively less prevalent, with osteomyelitis being a deeper and more severe bone infection, while impetigo, although common in children, is often related to other pathogens and presents differently than typical localized staphylococcal infections. Thus, the localized purulent infection of the skin stands out as the most frequent presentation among staphylococcal infections.
