Like Free Tally said, if hundreds or thousands come down with the disease in the next few days, then there will be something to worry about; we can assume that tyhere has been a bio attack.

If I remember my Army CBR/NBC training, the incubatiuon period is seven-10 days.
Sorry to stutter. No excuse.
"Coincedences" should read "Coincidences".
