To determine:
How Jason and Julie possibly got infected, why CA-MRSA is considered as an evolving disease, given that MRSA has been around for years, and why the map does not display more countries in South America and Africa with cases of CA-MRSA.
Case summary:
Julie was surprised and feels very proud that her boyfriend bought her a tattoo as an 18th birthday gift. After a week, Julie and Jason are affected by an evolving disease, which is referred to as community-associated, methicillin-resistant Staphylococcus aureus (CA-MRSA) diseases. Julie’s leg and arm are layered with swollen, red, and painful lesions (containing pus); soon, she developed fever. Jason misunderstood that he suffered a spider bite (Wednesday). On the next day, he is unable to walk, and he noticed a red-color line going up from his ankle to his groin. Soon, his health condition became worse and he was hospitalized for 10 days.
He was severely affected by bacteremia (blood) and osteomyelitis (his bones are affected). For many years, the health center workers fought to control healthcare-associated MRSA (HA-MRSA). Usually, the HA-MRSA infects hospitalized patients, but in recent years, common people (other than hospitalized patients) are also affected; for example, risky tattooists, school students, and athletes. It is spread by sharing clothes, fomites, razors, and towels.
Julie is suggested oral antimicrobials such as doxycycline, trimethoprim-sulfamethoxazole, and clindamycin) and she was given vancomycin (intravenous).

- Gram positive case on the first day back to class at the local university, a student noticed a small abscess on his right elbow but didn't think much about it. Over the next couple days, however the abscess became more swollen and painful. The student decided to visit the health centet he told the doctor it looked like a spider bite but didn't recall being bitten. The doctor took a swab of the lesion and prescribed an antibiotic cream as it looked infected. The swab was sent to the lab for testing within a few days of treatment, the student lesion was healed.

How else does this organism spread to cause this disease?arrow_forwardGram positive case on the first day back to class at the local university, a student noticed a small abscess on his right elbow but didn't think much about it.
