How does community-associated MRSA differ from MRSA seen inside healthcare facilities?

1. MRSA infections are common among people in healthcare facilities, where the average age of those affected is 68. 2. MRSA has also appeared in healthy people who were never hospitalized. 3. Those cases arise where people live or work in tight populations, such as military personnel and prisoners. 4. Community-associated MRSA, or CA-MRSA, affects people whose average age is 23. 5. Researchers are concerned precisely because this source targets a much younger population. 6. The trap is reversing the two averages, so 68 belongs to healthcare facilities, not to the community strain. 7. CA-MRSA is still MRSA, so it remains resistant to methicillin. _Source: OpenStax Biology (1st ed., CC BY 4.0), Ch 22 "Prokaryotes: Bacteria and Archaea", section 22.4 Bacterial Diseases in Humans_
