This has been brewing for several years now but it is sadly becoming a frequent problem.  Severe skin infections caused by MRSA (Methicillian Resistant Staph Aureus.)
MRSA is a Staph A. bacteria.  MRSA is a form of this bacteria that has developed resistants to several classes of antibiotics.  What has made this Bacteria scary in the community is it's production of potent toxens that make it an increasing cause of skin infections.  These infections have been frequently misdiagnosed (often attributed to spider bites, which are very rare!)  The poor Brown Recluse spider is also frequently blamed but is rarely the cause.
All should be aware and vigilant of severe (often blistering) skin infections and should seek medical attention to have them treated.  Of note: the community form of MRSA is different from the Hospital aquired form of MRSA.  Confusing, but the distinction is important because they are treated differently.
