Dr. Jeff Parks, an Ormond Beach dermatologist, said he has treated at least eight patients in the last two months with the painful and contagious crater-like lesions that start as small pustules and can expand to the size of silver dollars within days. He said his patients with methicillin-resistant staphylococcus aureus, better known as MRSA, ranged in age from 3 to 40 years old. While the cause is difficult to pinpoint, Parks said each patient had swum in the ocean right before contracting the illness.
Bacterial infections are common among commercial fishermen and others who handle fish. But Parks and others are perplexed about why and how so many people are contracting this particular strain of bacteria, which is believed to be acquired only on land.
Until this year, Parks said he hadn't seen a single case of MRSA in "people who have casual contact in the water."
"Normally, it's land-borne. But I think it is in the water, or on an organism in the water," he said. "It's happening to people who are not exposed on land."
The bacterial infection usually affects people with weakened immune systems, including cigarette smokers, often in hospitals, nursing homes and other medical facilities. Left untreated, it can result in massive infection, amputation and even death.
"All my patients were otherwise healthy. They had no obvious traumatic cuts," he said. "Traditionally, there needs to be an opening" for the bacteria to enter.
Gary Hill, the 36-year-old kitchen manager at Our Deck Down Under, works next to the Port Orange Marina where at least 10 offshore commercial fishermen have contracted the bacterial infection in recent months.
A twice-a-week surfer, he went to Halifax Medical Center in Daytona Beach on Sunday, concerned about two suspicious lesions on his right leg, after reading a News-Journal story about the bacterial infection.
Hill immediately was admitted and placed on intravenous antibiotics.
He said a doctor about two weeks ago misdiagnosed "the little pimple" as an infected hair follicle. Subsequently, the lesions spread, developing into half dollar-sized open sores on his thigh and armpit.
Hill said he last surfed about three weeks ago. Recently, he said he went out on a one-day charter-fishing trip, but no one else aboard became infected.
