What does "in the midst of a rash" mean?
Thanks a bunch.
A rash is a scattered occurrence of something unwelcome. Originally it referred to a medical sign; here's a rash in this physical sense: http://upload.wikimedia.org/wikipedi..._17th_dose.JPG
But there is a perhaps more widely used metaphorical use; there could, for example, be 'a rash of burglaries'; this is nothing to do with itchy criminals.
Returning to your question, something might happen 'in the midst' [=right in the middle] of this kind of rash. So that in a possible TV crime drama a detective might say to a sceptical colleague:
There has been an outbreak of dozens of crimes using exactly the same MO [=modus operandi='way of working']. And you're asking me to believe that the latest burglary - the same sort of target, the same MO, the same ... everything - ... that in the midst of a rash of similar break-ins, this one heist was pulled off by a new 'perp' [=perpetrator, culprit]? I don't buy it.
