On the news tonight, there was a report about the Zika virus.  We were assured that those in the St. Louis area who have contracted the disease were infected as a result of traveling to areas in which Zika is endemic.  In St. Louis, Zika is a concern, however, partly because, as the reporter said, “At least one mosquito native to this area is a known carrier of Zika.”

One mosquito???!!!  There’s one mosquito to worry about???!!!
