About MRSA skin infection
Methicillin-resistant Staphylococcus aureus (MRSA) is a Staphylococcus aureus strain resistant to beta-lactam antibiotics. Community-associated MRSA frequently presents as skin and soft-tissue infections — boils, abscesses, or cellulitis that often resemble spider bites. Risk factors include skin breaks, athletic contact, crowded living, and prior MRSA. Drainage of abscesses is the most important intervention; oral antibiotic options include trimethoprim-sulfamethoxazole, doxycycline, or clindamycin based on local resistance. Decolonization and household hygiene measures are considered for recurrent infections.
