That appears to be changing. Today, the BBC's Radio 4 broadcast a documentary, "The Bug That Can Kill Within Hours," that focuses on fears of a dramatic rise in the UK of cases of serious community MRSA. According to the UK's Health Protection Agency, lab-confirmed cases of community MRSA strains hit 1,361 in 2007, three times what they were the year before. (Soundfile here, starts automatically.)
The documentary refers to CA-MRSA as "PVL-MRSA," a recognition of the fact that most of the community strains produce the toxin Panton-Valentine leukocidin, or PVL. (PVL is known to destroy white blood cells, but whether it is responsible for the virulence of CA-MRSA is a hotly disputed question in MRSA research.) Aside from the difference in terminology, any of the statements from the accompanying BBC website story could have been said here any time in the past 10 years:
Professor Brian Duerdan, the Inspector of Infection Control at the Department of Health, admits however that many aspects of this virulent bug are a mystery.People who have been tracking the relentless expansion of CA-MRSA, espeially its dominant clone USA 300, are likely to find some of the statements in the documentary both troubling and poignant. The UK is beginning to deal with some of the wuestiosn that the US has struggled with: how much surveillance to do, how to spend scarce research dollars, and what the consequences may be if CA-MRSA is not focused on now.
"We do know that it spreads in the community amongst close contacts, families, people who share the same sporting events. But we still need to know a lot more about its exact prevalence in the community," he said.
Hugh Pennington, Emeritus Professor at the University of Aberdeen, and President of MRSA Action, told the BBC that the HPA lacks the resources to keep proper surveillance on outbreaks of infection from this strain of bugs.Indeed.
"The scandal here is that we know what to do, the technology's there to spot these things as they are appearing and we know how to react to them.
"It would be quite wrong if we allow these things to develop and of course history tells us that it we do neglect these bugs, we neglect them at our peril."
