3. SENTINEL PROVIDER SURVEILLANCE:
Thirty-eight (29%) of 129 New York State and New York City sentinel providers for influenza surveillance
submitted 102 respiratory specimens to the NYSDOH Wadsworth Center for testing. Two specimens were
positive for respiratory viruses other than influenza, as noted in the table below. Fifty-three specimens (52%)
tested positive for influenza: 36 (68%) were influenza type A and 17 (32%) were influenza type B. Of
the 36 influenza type A positives, 18 (50%) were A(H1N1), 15 (42%) were A(H3N2), and 3 (8%) were A,
not subtyped. One influenza A(H1N1) specimen was also positive for adenovirus type 4.
