The WSLH thanks you for your cooperation and assistance in influenza surveillance and the response to 2009 H1N1 Influenza A.

Laboratories are asked to submit the following specimens for influenza surveillance:

  • All specimens that are positive for influenza by any test
  • Up to five specimens each week that were received with a request for influenza testing
  • Up to ten specimens each week from laboratories that were recruited and enrolled in influenza surveillance last fall
  • Specimens from healthcare providers who were recruited and enrolled in influenza surveillance last fall
