Prognosis and Complications
- Direct person-to-person transmission of group A strep can occur through contact with skin lesions or exposure to respiratory droplets.3 People with active infection are more likely to transmit group A strep compared to asymptomatic carriers. Local dermatophyte infection (e.g., athlete’s foot) may serve as portal of entry for group A strep.1
Prevention
- Disruption of the cutaneous barrier, such as presence of ulcers, wounds, or fungal skin infections (e.g., athlete’s foot), is a risk factor for developing cellulitis.1,4,5 Previous history of cellulitis; venous insufficiency, presence of chronic edema, or impaired lymphatic drainage of the limbs; obesity; and injection drug use have also been identified as risk factors for cellulitis.1,4,6
