OK, so this one is pretty lame, but here goes:
Apparently, boxer Clinton Woods was suffering from aseptic meningitis during his world title defeat to Antonio Tarver. After consulting Medline Plus (I'm a little rusty, okay?!), I remembered that nearly half of the cases of aseptic meningitis are due to coxsackie and echoviruses (both picornaviruses). Other possible viral causes listed include HIV acute retroviral syndrome, herpes viruses, mumps, and West Nile. Also, he should be tested for certain fungi and mycobacteria and it should be determined which meds he was recently taking, because these, too, can cause meningitis.
