A new study by the Centers for Disease Control and Prevention (CDC) estimates that methicillin-resistant staphyloccus aureus (MRSA), also known as the superbug, strikes 31.8 out of every 100,000 Americans, making it more common than flesh-eating strep infections, bacterial pneumonia and meningitis combined. 94,000 serious infections and 19,000 deaths each year can be attributed to the disease, making it more deadly than AIDS. MRSA is most prevalent among African Americans and the elderly, and is also common with very young children under one year of age.
