This is a breaking story. A kid in Sacramento coming back from Cancun has experienced flu-like symptoms, and swabs are being sent to CDC for further testing. Seven of his classmates also came down with flu-like symptoms.

“A seventh-grader at St. Mel who recently returned from a family vacation to Cancun, Mexico, felt ill last Monday and went home. On Wednesday, a classmate also missed school with flulike symptoms, and by Friday seven students were out, including four who complained of flulike symptoms, said Kevin Eckery, a spokesman for the Catholic Diocese of Sacramento. ”

Note that this does not prove there is flu in Cancun. The kid might have gone thru Mexico City, or be infected in some other way. We will be monitoring the situation closely and will report it here.
