Through 1 December 2012

So What Happened in 2010 and So What Happened in 2010 and 2012?2012?

• Climate? Very hot and very dry leads to reduced availability of water.

• Reduction in routine mosquito control? Kept WNV in check before?

• Role of volunteer blood donor positives

• Had 19 volunteer donor positives—more than all other years combined.

• Most not symptomatic or unknown.

• Initially thought test may be flawed, but better reporting

• Surveillance system worked in identifying WNV

Lyme disease 2012 vs. 2011 (reported cases through 12/4 each year)
