In fact, new strains have recently emerged in the community that are capable of causing severe infections in otherwise healthy individuals. These MRSA infections are known as community-associated MRSA. MRSA infections that are first acquired in the hospitals and healthcare facilities are known as healthcare-associated MRSA.
