Hawaii's Influenza Surveillance Program
Influenza Surveillance Report
Latest Update: April 29-May 5, 2012: Week 18, 2012
During week 18 of the 2011–12 influenza year, 3.1% (95% CI 2.0–4.3%) of outpatient visits to Hawaii sentinel providers were attributable to influenza-like illness (ILI). Outpatient ILI reported during week 18 of 2012 was lower than the historical baseline in Hawaii (p<0.05) , but was comparable to the national baseline (2.4%) and higher than the national ILI (1.4%).
The chart below displays the total volume of specimens tested for influenza by MMWR week during the 2011-12 influenza season, as well as the sub-set receiving confirmatory testing. Proportion of specimens positive for influenza viruses by type and sub-type is only presented for specimens tested by confirmatory tests (i.e., RT-PCR or viral culture).
